Each animal has HP. Beat it enough times to deplete its health and unlock the next — faster — creature. Can you reach the Dragon?
Sprinting does more than build speed. Leg It! tracks 6 science-backed health dimensions and rolls them into a single Health Score — from 0 to 100 — so you can see exactly what your training is doing to your body.
Three GPS-tracked interval presets guide you from warmup through timed sprints and measured rest — with a per-rep speed reading, peak, and a fade score at the end so you know exactly how you performed.
Every week you're placed in a competitive pool. Sprint your hardest, earn ranking points, and try to top your pool. Rankings reset every Monday and Thursday — no lead is permanent.
31 of the most celebrated athletes — from basketball stars to sprint champions. Match their recorded top speed to advance. Beat them all to conquer The Gauntlet.

Relay races bring your crew together. Each runner contributes their leg of the race — combined efforts determine the team's result. Every member matters.
Pick any friend and challenge them directly. Your best sprint in the session goes up against theirs — the faster runner wins. Streaks track your winning record.
Every sprint you run earns weekly points that go toward your school's ranking. K-12 students and college alumni each compete on their own leaderboard.
Pick a speed you want to hit — 12 mph, 15 mph, your first sub-10-second sprint — and the app tracks your progress every time you run. When you hit it, you'll know.
XP, levels, badges, mastery tiers — Leg It! turns running into a progression system. The faster and more consistent you are, the more you unlock.
After every 3 sprints, your AI Coach analyses your data and writes personalised coaching cards — each with a specific diagnosis and a concrete drill prescription for your next session.
Leg It! gives coaches a dedicated dashboard to build rosters, assign sessions from a 17-drill library, set speed goals with deadlines, and track every athlete's progress in real time — all without leaving the app athletes already use to sprint.
Coaches build rosters, assign sessions and goals, track athlete progress, and watch sprint data as it comes in — all inside Leg It!. Athletes get everything in one tab, with push notifications the moment anything is assigned.
