How to Run a 40-Yard Dash: Setup, Technique & Timing
Master the setup, form, and timing secrets that separate average sprinters from elite 40-yard dash performers.
Use a laser-based 40 yard dash timer for accurate, reproducible splits. Set gates at hip height, measure exactly 40 yards from start line edge to finish line edge, and run the same stance every session. Hand timing introduces 0.10 to 0.20 seconds of variability; electronic systems eliminate that entirely.
- 0.10 to 0.20 second hand-timing gap: Manual timing introduces 0.10 to 0.20 seconds of variability between timers, and NFL Combine data shows hand times running about 0.24 seconds faster than electronic times on the same athletes.
- Gate height at hips: Timing gates belong at hip height so the beam crosses where the torso breaks the plane, because a beam set too low can be triggered by a leaning arm before the athlete actually moves.
- 60 to 70 percent forward weight: In a three-point stance, loading 60 to 70 percent of your weight over the front foot sets up a more explosive first step, but the stance you pick must stay consistent across all testing sessions.
- Five minutes between attempts: Rest at least five minutes between maximum-effort runs, and enforce a standardized 15-minute warm-up every time, because protocol differences are just as damaging to data quality as a loose measuring tape.
- Speed and agility are distinct: Athletes who test well on the 40 do not automatically test well on agility drills, so programs relying only on straight-line speed are missing a significant part of the picture for most field sport athletes.

Why the 40-Yard Dash Still Sets the Standard
Few drills carry as much weight in athletic evaluation as the 40-yard dash. It started as an NFL Scouting Combine staple, chosen because 40 yards roughly matches the distance a punter's hang time gives a coverage player to run downfield. That origin stuck, and the drill has since become the default measure of straight-line speed across football, lacrosse, soccer, track, and strength and conditioning programs at every level.
The reason it endures is that it captures something genuinely useful: explosive acceleration out of a static start, combined with top-end velocity maintenance. A 10-meter split tells you about first-step quickness. A flying 40 tells you about pure speed. The standard 40-yard dash tells you both in a single effort, which is why coaches still rely on it when they want one number that summarizes an athlete's linear speed profile.
The problem is that getting an accurate, reproducible time requires more care than most programs give it. Hand-timing introduces meaningful variability, course setup errors can invalidate comparisons, and technique mistakes leave time on the ground. Each of those variables is fixable, and fixing them turns a rough estimate into a real performance metric.
Course Setup: Surface, Distance, and Gate Placement
A 40-yard dash is only as reliable as the ground it is run on. Grass, turf, and hardwood track differently, and while you cannot always choose the surface, you can control where the gates go and how the course is marked. Measure from the front edge of the start line to the front edge of the finish line, not from cone to cone or gate post to gate post. That 40 yards is precise, and a foot of drift compounds across many athletes and testing sessions.
Timing gates should sit at hip height for a standard tall-gate configuration, which keeps the beam crossing at roughly the point where an athlete's torso breaks the plane. Too low and a leaning arm triggers the start gate prematurely; too high and the system misses athletes of shorter stature. Most multi-gate setups include adjustable tripods that allow you to dial in consistent beam height across all gate positions, which matters especially when you add intermediate split points at 10 yards or 20 yards.
For outdoor testing, surface reflectivity and direct sunlight can interfere with laser-based systems. The Dashr systems address this with optional heat shields and reflectors designed to reduce interference from ambient light. If you are running tests on a bright turf field in summer, those shields are not optional equipment, they are part of getting clean data. Indoor tracks and fieldhouses eliminate most of that interference, which is one practical reason programs with access to indoor facilities tend to produce more consistent test-to-test numbers.
Hand Timing vs. Laser Timing: What the Difference Means
Hand timing is still common in high school programs and smaller college programs, mostly because it requires no equipment investment. The trade-off is real, though. Research on reaction-time variability in manual timing consistently documents differences of 0.10 to 0.20 seconds between timers watching the same run, and average hand times tend to run faster than fully automatic times partly because a human timer often starts the watch slightly after the athlete moves. Aggregated NFL Combine data has shown hand times running roughly 0.24 seconds faster than electronic times on the same athletes.
That gap matters if you are trying to compare your athletes to published norms or scholarship-level benchmarks. A running back who runs a 4.55 hand time might be recording a 4.75 or 4.80 under a laser system, which puts him in a very different category. None of that is a criticism of hand timing as a rough tool; it is just a reason to be careful about which benchmarks you compare to and to use the same timing method consistently within your program.
Laser timing systems eliminate timer reaction time entirely. The gate starts on athlete movement and stops on crossing, with no human in the loop for either event. The Dashr 4-Gate system, for example, captures real-time data and sends it directly to the Dashr app, so the coach sees the split and final time immediately without writing anything down. That eliminates transcription errors along with the timing variability, which compounds into more reliable longitudinal data across a training cycle.
For programs that track athletes over months or years, the consistency of electronic timing is worth more than the raw accuracy on any single day. A 0.03-second improvement from week four to week eight only means something if the measurement tool is stable enough to detect it. Hand timing rarely is. Laser timing, reliably set up, generally is.
Start Position Mechanics: Three-Point vs. Two-Point
The NFL Combine uses a three-point stance, and that is what most football programs test in. Athletes from other sports, and many youth programs, run from a two-point ready stance. Both are valid, but they are not interchangeable for comparison purposes. You need to pick one for your program and stick with it, because the stance changes the first-step mechanics enough to shift the time by several hundredths of a second.
In a three-point stance, the dominant hand is down just behind the start line, with the opposite foot forward and the back foot roughly hip-width back. Weight should be distributed forward, somewhere around 60 to 70 percent on the front foot. The hips stay slightly higher than the shoulders, which allows a more horizontal drive angle out of the stance rather than a vertical pop. Athletes who stand up too quickly in the first three steps lose ground contact time and sacrifice acceleration.
In a two-point stance, the technique is closer to a track-style acceleration start. Feet staggered, hips low, weight forward over the balls of the feet. The arm opposite the lead foot should be forward, ready to drive back on the first step. Many athletes default to an upright ready position here, which produces a slow first step and early transition to upright running before they have built any real speed.
The First Three Steps
Regardless of stance, the first three steps determine the quality of the run more than any other phase. Each step should be short and powerful, driving back and down rather than reaching forward. A reaching first step puts the foot in front of the center of mass, which creates a brief braking force rather than propulsion. The goal is ground contact behind or directly under the hips for as long as possible during the acceleration phase.
Most athletes who run disappointing 40 times are not slow at the top end. They are slow in the first 10 yards. Video analysis on a phone, shot from the side, will show you whether an athlete is accelerating efficiently or popping upright in the first few steps. That is a correctable mechanical problem, and fixing it with focused drills is usually faster than building raw speed.
The Acceleration Phase: Yards 1 Through 20
The acceleration phase runs from the start through roughly the 20-yard mark for most athletes. During this phase, stride length is shorter than at top speed, ground contact time is longer, and the body angle is more forward-leaning than it will be once the athlete reaches full velocity. Fighting the urge to stand up is the central technical challenge of this phase.
Arm mechanics contribute significantly here. Short, compact arm drives at the start allow the legs to cycle faster. As speed builds, the arms extend more fully, but they should stay in a relatively tight arc, not swinging across the body. Cross-body arm swing wastes energy in rotation, which the lower body then has to counteract, and it disrupts the linear drive pattern that straight-line speed requires.
Many programs add a 10-yard split to their 40-yard dash testing protocol precisely because it isolates the acceleration phase. If an athlete has a strong 10-yard time but the full 40 is slower than expected, the problem is in the transition to top speed or in top-speed mechanics. If the 10-yard time is poor, the start and initial acceleration are the priority. The Dashr 5-Gate system supports exactly this kind of multi-split setup, with five gate positions that can be configured to capture as many intermediate splits as the drill design requires.
Top Speed and the Final 20 Yards
Most athletes hit peak velocity somewhere between 20 and 35 yards, depending on their training background and the quality of their acceleration. The final segment of the 40 is less about accelerating and more about holding what has been built. Deceleration in the final 10 yards is common, especially in untrained athletes, and it can cost several hundredths of a second off the final time.
At top speed, the body angle is much more upright than during acceleration, hip extension is longer, and stride length reaches its maximum. Ground contact time is short, and the focus should be on cycling the legs quickly rather than driving back hard. Relaxation through the upper body becomes important here; tension in the shoulders and neck transfers down the kinetic chain and tightens the hip flexors, reducing stride frequency.
A simple cue that works for most athletes is to run through the finish line rather than to it. Athletes who anticipate the finish line often decelerate before they cross it, which is a measurable and preventable loss. With laser timing, you can see this clearly when you have a split at 30 or 35 yards and the time to 40 is disproportionately slow relative to earlier splits. That pattern in the data points directly to a premature deceleration habit.
Choosing the Right 40-Yard Dash Timer for Your Program
The right setup depends on how many athletes you test, how often you test them, and what you plan to do with the data. A system that fits a single personal trainer working with a handful of clients looks very different from one running combine-style evaluations for a high school football roster.
At the entry level, a single-gate system gives you a finish-line timer that starts manually or from a contact mat. It captures final time but no splits, which is limiting if you want to diagnose where in the run an athlete is gaining or losing time. The Dashr 1-Gate system, priced at $375, fits programs that need a reliable, consistent time for one distance and are not yet focused on split analysis. It works for the 40-yard dash as a single-point measurement.
The step up to a two-gate or three-gate configuration opens split timing, which transforms the data you collect. A 10-yard split and a 40-yard finish time together tell you something actionable. The Dashr 2-Gate system at $690 supports dash and flying drills along with pro-agility and T-test configurations, so the same system handles multiple evaluation protocols across a training week. The Dashr 3-Gate system at $990 adds one more position, which can sit at 20 yards for a cleaner picture of the full acceleration and top-speed phases.
For programs running combine-style multi-drill evaluations, the Dashr 4-Gate system at $1,300 and the Dashr 5-Gate system at $1,600 offer the most flexibility. The 4-Gate system includes an optional vertical jump testing feature and supports a customizable athlete roster with real-time app integration. The 5-Gate system adds a fifth gate position, which allows more granular splits or simultaneous lane setups for some drill configurations. Both include aluminum carrying cases, which matters more than it sounds when a system travels between facilities or fields.
Dashr System Comparison: Gates, Price, and Drill Support
The table below covers the full Dashr lineup available through Peak Primal Wellness, including the standalone modules. Gate count drives most of the capability difference, but the Blue Laser upgrades and add-on gates give existing owners a path to expand without replacing the whole system.

5 | $1,600 | Five-position flexibility, up to 5 tall or 2 short gates |
 Dashr Blue Laser Module |
1 module | $315 | 100m Bluetooth range, heat-resistant, standalone upgrade |
 Dashr Blue Laser Upgrade 2.0 |
1 module | $250 | Enhanced Bluetooth, 100+ yards range, modular expansion |
The Blue Laser Upgrade 2.0 is worth noting for programs already running an older Dashr system. The enhanced Bluetooth protocol extends range to over 100 yards and speeds up the connection process, which adds up to meaningful time savings across a full testing day. The improved reflector design on the upgrade also reduces interference from external light sources, a practical benefit for outdoor testing at any time of year. If your existing lasers are a generation behind, the $250 upgrade is a more cost-effective path than replacing the full system.
Building a Repeatable Testing Protocol
The technical side of running a clean 40-yard dash test is only half the picture. The other half is protocol consistency, and it matters just as much for getting data you can actually use. If athletes warm up differently, rest differently, or run on different surfaces across testing sessions, the numbers become difficult to interpret. You cannot separate a real improvement from a protocol difference.
Standardize the warm-up and enforce it. A 15-minute progressive movement routine followed by three build-up runs at increasing intensity gives most athletes reliable readiness without accumulating fatigue. Rest between attempts should be at least five minutes for a maximum-effort 40-yard dash. Some programs allow only two timed attempts per session to protect data quality and reduce injury risk, taking the faster of the two.
The Dashr app handles athlete management and data storage, which removes the paper trail problem. Coaches can run full sprint testing batteries across a roster and have every split and final time stored against each athlete's profile by the end of the session. That longitudinal record is where the real value of electronic timing shows up: you can pull any athlete's progression over a full training cycle and see exactly which phase of the sprint has improved and which has not.
Testing frequency is a genuine question. Monthly testing gives enough time for meaningful physical adaptation to occur between sessions. More frequent testing can be useful when you are specifically trying to evaluate a technical change, but it becomes noise if the athlete has not had time to adapt. Most strength and conditioning programs settle on testing at the start of a training block, at the midpoint, and at the end, which gives three data points per cycle and a clear picture of training effect.
Expanding Beyond the 40: Agility and Multi-Drill Testing
Once you have a reliable 40-yard dash setup, the natural next step is adding agility drills to your testing battery. Speed and change-of-direction ability are related but distinct qualities, and athletes who score well on one do not always score well on the other. Programs that test only straight-line speed are missing half the picture for most field sport athletes.
The Dashr systems support pro-agility (the 5-10-5 shuttle), T-test, and lane agility configurations using the same hardware as the 40-yard dash. Repositioning the gates takes a few minutes, and the app handles drill selection automatically. For youth athletes in particular, the combination of a sprint time and an agility score gives coaches a much more useful developmental profile than either metric alone.
Reaction training is a logical complement to speed testing. An athlete who runs a 4.5 but reacts slowly to a visual or auditory cue may be functionally slower on the field than a 4.6 athlete with sharp first-step reaction. If you are building out a full performance testing and training setup, browsing the reaction training collection alongside your timing system selection gives you a more complete picture of what the training environment can support.
The modular design of the Dashr line means you are not locked into the gate count you start with. A program that begins with a 3-Gate system and grows to need five gates can add the 1-Gate Add-On rather than replacing everything. That scalability is a real practical advantage for programs with growing athlete rosters or expanding testing protocols, and it is one of the clearer reasons to invest in a platform-based system rather than a fixed-configuration timer.
For programs evaluating the full Dashr lineup before committing to a gate count, a closer look at how each configuration performs across different drill types is worth the time. The differences between a 3-Gate and a 4-Gate setup are not always obvious from a spec sheet, and the right choice depends on which drills your program actually runs. Similarly, coaches who are weighing Dashr against other wireless systems will find the connectivity and app integration features are where the practical day-to-day differences show up most clearly.
The full range of timing systems covers entry-level single-gate setups through multi-gate wireless configurations, so the scale of your program and your testing goals will point you toward the right starting point. The 40-yard dash is where most programs begin, but the system you choose should be capable of growing with you as your testing battery expands.

Frequently asked questions
Does a laser timing system actually make a meaningful difference for a 40-yard dash, or is hand timing good enough?▾
Hand timing introduces 0.10 to 0.20 seconds of variability between timers watching the same run, and aggregated NFL Combine data shows hand times running roughly 0.24 seconds faster than electronic times on the same athletes. That gap is large enough to put a running back in a completely different speed category. For any program tracking improvement over a training cycle, a laser system is the more reliable tool because a 0.03-second gain only means something if your measurement instrument is stable enough to detect it.
What is a 40 yard dash timer and how do laser gate systems work?▾
A 40 yard dash timer is an electronic timing system that uses laser beams stretched across the course to record splits and finish times automatically, with no human starting or stopping a watch. The athlete breaks the first beam to start the clock and breaks the finish beam to stop it. Systems like the Dashr 4-Gate capture that data in real time and send it directly to a companion app, so the coach sees the result immediately without any manual transcription.
How should timing gates be positioned for accurate 40-yard dash results?▾
Gates should sit at hip height in a standard tall-gate configuration so the beam crosses at roughly the point where the athlete's torso breaks the plane. Too low and a swinging arm can trigger the start gate early; too high and shorter athletes may not reliably interrupt the beam. Measure from the front edge of the start line to the front edge of the finish line, not from cone to cone, since even a foot of drift compounds across a full testing day.
What does a quality wireless timing system cost, and what does that price actually include?▾
Entry-level wireless gate systems start well below four figures, while multi-gate setups designed for comprehensive speed and agility testing run higher. The Dashr 4-Gate system is priced at $1,300 and includes four timing gates, laser modules, tripods, heat shields for outdoor use, and a portable aluminum carrying case. The Dashr 5-Gate system is $1,600 and supports up to five tall or two short gates, includes 10 free roster spots, and also ships with an aluminum case for storage and transport.
Can one timing system handle drills beyond the 40-yard dash?▾
Yes, and this is one of the stronger arguments for investing in a multi-gate setup rather than a single-beam finish-line timer. The Dashr 4-Gate and 5-Gate systems both support pro-agility, T-tests, flying drills, and lane agility in addition to standard dash testing. The modular design also means you can reposition gates to create 10-yard or 20-yard split points within a 40-yard run, which gives you acceleration and top-speed data from a single effort.
How do you expand a timing system as a program grows?▾
Dashr systems are built with expansion in mind. The Dashr 1-Gate Add-On ($375) upgrades an existing setup by adding one tall timing gate, complete with two tripods, a laser module, and a reflector, effectively converting a 2-Gate system into a 3-Gate configuration. Individual Dashr Blue Laser modules ($250 each) can also be added; they feature an enhanced Bluetooth protocol with a range of 100 or more yards and are backward-compatible with existing Dashr hardware.
What are the most common setup mistakes that produce bad 40-yard dash times?▾
The biggest one is imprecise measurement. Marking the course from cone center to cone center instead of front-edge to front-edge can shift the distance by several inches, which matters when you are comparing athletes to published norms. Outdoors, skipping heat shields on a laser system is another frequent error; direct sunlight and surface reflectivity genuinely interfere with beam consistency. Inside, the problem mostly disappears, which is one practical reason indoor testing tends to produce tighter numbers across a full group.
Does stance choice affect 40-yard dash times, and how should a program handle it?▾
Stance choice shifts the time by several hundredths of a second because it changes first-step mechanics, so a three-point stance and a two-point ready stance are not interchangeable for comparison purposes. The NFL Combine uses a three-point stance, and most football programs follow that standard. The key rule is consistency: pick one stance for your program and keep it across every testing session, because mixing stances within a dataset makes longitudinal tracking unreliable regardless of how good your timing equipment is.
