The World Indoor Track & Field League 2026
The TrackFIT 40 Yard Dash Challenge. Discover How Much Faster You Can Run.
Powered by TrackFIT 3D Intelligence™
Motion DNA™ Signature Tracking
A stopwatch tells you your time. TrackFIT tells you why.
Across 11 intervals of 40 yards each, we measure what impacts your speed, power, explosiveness, and technique — and how to get faster instantly.

The Questions You've Been Asking
If You Want More Speed, Power, And Explosiveness — This Is Where You Find Out Why.
Every athlete wants to know what makes them fast, what is costing them speed, and how much more they are capable of. TrackFIT 3D Intelligence™ answers it with real data — outside of a lab, for the first time ever.
Speed + Power
⚡
Am I explosive enough?
TrackFIT 3D Intelligence™ measures usable force output, acceleration profile, and how much power you produce rep after rep.
💥
Why do some athletes look more powerful even when the times are close?
Pounds of effort force, pounds of impact force, and pound-for-pound output show who is producing more real power — not just a similar time.
🚀
Why am I not accelerating better?
TrackFIT measures early-run force production, velocity build, and mechanical efficiency so you can see whether the gap is power, mechanics, or both.
🏋️
Do I need more strength — or do I just need to use it better?
Pound-for-pound scoring shows whether your issue is force production itself or how efficiently your body converts force into speed.
🦵
Am I creating force into the ground the right way?
Impact and effort force per step show how you load, strike, and push — and whether that pattern is helping or costing you speed.
🔥
Why do I lose pop after a few reps?
Repeat-speed data shows exactly when force output, efficiency, and explosiveness start to fall off across the 11 runs.
Mechanics + Speed
⏱
Where am I losing speed?
Rep-by-rep times, velocity curves, stride length, stride rate, and efficiency reveal exactly where speed leaks out of your run.
📏
Is my stride length helping me or hurting me?
TrackFIT measures step length relative to height and shows how your stride changes as you run faster and as fatigue builds.
🔁
Can I repeat speed — or am I just fast once?
The 11 x 40 format shows whether you can hold output, mechanics, and speed across reps — not just hit one good run.
🧠
What is my body actually doing when I run?
TrackFIT captures your Motion DNA™ Signature — the compensation patterns, mechanics, and force behaviors unique to you.
🏃
Are my mechanics making me slower?
Execution scoring separates mechanics from raw performance so you can see if your technique is costing you speed even when effort is high.
📉
Why does my form change when I get tired?
TrackFIT shows the exact rep where step pattern, force output, and efficiency shift so breakdown is measured, not guessed.
Potential + Progress
📈
How fast can I become?
TrackFIT uses your actual output, efficiency, and repeat-speed data to define potential based on what your body is showing right now.
🏆
What separates me from the next level?
Performance, Execution, and Pound-for-Pound scores show whether the next jump comes from more output, cleaner mechanics, or better force efficiency.
🎯
What should I train first?
Your lowest scoring variable tells you the biggest opportunity first, so you can stop guessing and attack the right thing.
🔬
I feel good. I just want objective data.
TrackFIT gives you pounds of force, speed data, mechanical scores, repeat-speed breakdown, and your TrackFIT Score. Numbers. Not opinions.
🎓
How do I prove my value beyond a stopwatch?
A time tells what happened once. TrackFIT shows how you produced it, how repeatable it is, and what your ceiling says about where you are headed.
🌟
Where do I actually stand?
Your TrackFIT Score combines Performance, Execution, and Pound-for-Pound into an objective measure of how complete you are as an athlete.
Every One Of These Questions Has An Answer
And It Starts With Data You Have Never Had Before.
Speed is not just about time. Power is not just about effort. Explosiveness is not just how it looks.
TrackFIT measures what makes you fast — and shows where more speed is still available.

How The TrackFIT 440 Protocol Works
11 Sprints. 40 Yards Each.
Every Rep Reveals More.
Every Rep Reveals More.
This is not just one sprint. TrackFIT measures how you produce speed, power, and explosiveness across all 11 sprints — not just your best time. The 440 Yard Dash Protocol reveals your output, mechanics, efficiency, fatigue pattern, and Motion DNA™ Signature.
