When we run Photon Sports sprint profiles on youth athletes at Alexander Stadium, overstriding shows up in the majority of cases — across all sports, all ability levels, all age groups. It is not a niche problem. It is the default.
What Is Overstriding?
Overstriding happens when a runner lands with their foot significantly in front of their centre of mass. The foot contacts the ground ahead of the hips, and instead of propelling the athlete forward, the impact creates a braking force — essentially hitting the brakes with every stride.
In our data: Athletes who overstride show, on average, 12–18% longer ground contact times than efficient sprinters at the same speed. Every millisecond of unnecessary ground contact is speed left on the pitch.
The mechanism matters. When the foot lands ahead of the hips, the leg angle creates a net deceleration vector. The athlete's own momentum is working against them. This is why we regularly see players with excellent squat strength and good general fitness who are significantly slower than their physical profile would predict.
Why It's So Common in Youth Athletes
Overstriding develops early and goes uncorrected. Most coaches watching a young athlete sprint are focused on the ball, tactical position, or effort level — not stride mechanics. Without high-speed camera analysis or timing gates, the flaw is essentially invisible to the naked eye.
There's also a counterintuitive belief at play: longer stride = faster running. Coaches sometimes encourage athletes to "reach" or "stretch out" in sprints, inadvertently reinforcing the fault.
In our assessments, we see overstriding most severely in U12–U14 athletes who have been in sport for three to five years — old enough to have developed patterned movement habits, young enough that those habits haven't been formally coached.
What Our Camera Data Actually Shows
A Photon Sports sprint profile captures foot strike position relative to the centre of mass on every stride across a 30–40m sprint. Here's what a typical overstriding profile looks like vs. an efficient profile at the same velocity:
That 0.3 second penalty is decisive in sport. The difference between a centre-back winning a foot race to a through-ball and conceding a goal. Between a winger breaking past a defender and being caught.
The 3-Drill Fix
Drill 1: Wall Drill (2 × 10 reps each side)
Stand facing a wall, hands on the wall at shoulder height, body at a slight forward lean. Drive one knee up to 90 degrees, then actively pull the foot down and back — striking the ground under the hip. The cue is down and back, not forward and down. This retrains the foot strike position without the complexity of full sprinting.
Drill 2: A-Skip with Constraint (3 × 20m)
Standard A-skip mechanics but with a focus on dorsiflexion (pulling the toes up) and landing the foot directly under the hip. Placing a resistance band around the ankles at very low tension gives proprioceptive feedback about foot position. Perform at 60% effort — this is a mechanics drill, not a conditioning drill.
Drill 3: Wicket Runs (3 × 30m)
Place flat ground markers (or hurdle wickets) at consistent intervals calculated for a slightly shorter-than-natural stride length. Force the athlete to shorten their stride by constraining it physically. After 3–4 reps at the constrained length, remove the markers — most athletes will self-organise into improved mechanics. We use this in every EPP assessment follow-up session.
Important: These drills address the symptom. A full Photon Sports profile also tells you whether the overstriding has a force production cause (the athlete lacks the hip extension power to drive off efficiently) or a learned mechanics cause. The training response is different for each.
How Long to See Results
In our 12-week intervention data, athletes who present with significant overstriding and complete a mechanics-focused programme show measurable improvement in stride efficiency within 4–6 weeks. Sprint times typically improve by 0.1–0.3 seconds over 30–40m within a single 8–12 week block.
The key is measuring. Without a baseline sprint profile, you're guessing. With it, you know exactly what the fault is, how severe it is, and whether the intervention is working.
