High school relays is where most athletes get serious. The training schedule is real, the coaching is variable, and the form habits formed now follow you to college if you keep going. Here's the high school relays stack, phases that match HS competition, the form patterns coaches see most often, and AI tools that fit a HS practice.
Don't measure your high school relays only by the number on the scoreboard. Each phase has a HS-level standard, takeoff angle, approach speed, release timing. AI grades against those standards, not against pros.
Sprint coaches don't always know pole vault. relays coaches don't always have time for every athlete every day. AI fills the gap, a phase-by-phase read on every rep, available between practices.
HS athletes change a lot in a season. Form drifts, peaks, fatigues. Filming once a month and checking against AI keeps you honest about which way the form is actually trending.
Free first analysis, no account, works on any phone. The AI was built for the kind of side-on phone video a high schooler actually shoots at practice. No tripod, no pro camera, no editing software.
Follow up in chat and ask questions. The AI remembers your analysis and speaks the language of relays coaching.
Progression is non-linear. The ladder below maps marker behavior, typical relays performance, approach length, and last-5m approach speed to the technical focus that should dominate your training block.
| Level | Marker | Performance | Approach | Speed | Training focus |
|---|---|---|---|---|---|
| Beginner | First exposure to relay. | n/a | n/a | n/a | Hand position, baton grip, basic exchange in stationary. |
| HS Developing | Can complete a 4x100 without dropping. | 4x100: 50+ s (M), 56+ s (W) | n/a | n/a | Verbal timing, jogging exchanges, basic go-mark. |
| HS Top / Club | State-meet caliber. | 4x100: 42-46 s (M), 48-53 s (W) | n/a | n/a | Race-pace exchanges, speed retention, drive-out. |
| College | D1 / national-meet caliber. | 4x100: 39-42 s (M), 44-48 s (W) | n/a | n/a | Sub-0.05s exchange loss, leg-order optimization. |
| Elite | World-level relay teams. | 4x100: < 39 s (M), < 44 s (W) | n/a | n/a | Marginal exchange gains, world-record execution. |
This is the schedule a typical HS or club program uses during the in-season. Wednesday's drill focus rotates based on what AI form check flagged from the weekend's tape.
Individual sprint training (each leg works own distance).
Relay technique: stationary, walking, jogging exchanges. Go-mark calibration.
Race-pace exchanges in zone. 4-6 full-speed reps per pair.
Recovery / mobility.
Full 4x100 simulation if pre-meet. Or meet day.
Off.
Tape review of exchanges. Identify pair that needs adjustment.
