PRDay
Track Training That Adapts
Free · Designed for iPad. Not verified for macOS.
Make every meet a PR Day. Heat-adaptive workouts, 12-week plans for your event group, AI form checks, and parent weekly reports - built for American track athletes.
No coach can check the heat index, your event group, your level, and your race countdown every single morning. PRDay can.
PRDay is the track and field training app that adapts to YOU. Athletes set up in under a minute - open the app and today's workout is already there, adjusted for today's weather, your event group (sprints, mid-distance, jumps, or throws), your level, and how close your goal race is.
KEY FEATURES:
- Heat-adaptive training: WBGT heat flags (built on NATA/ACSM public heat-safety standards) automatically adjust your session. On orange-flag days, hard sessions move to the morning or swap to technique work. On red-flag days, you get an indoor plan instead of a heat casualty.
- Today's workout, zero planning: one recommended session per day with sets, reps, and target paces. A built-in interval timer with a screen that stays awake, big scoreboard-style numbers, and haptic feedback.
- 12-week periodized plans: full plan library for sprints and hurdles, mid-distance and cross country (xc) runners, jumps, and throws - build, peak, and taper phases included. Target paces are calculated from your own personal records using proven running math (Riegel/VDOT style equivalencies).
- PR tracking that never resets your streak: log marks for every event from the 100m to the 1600m and field events, rate each session 1-10 (RPE) in seconds, see your personal best progress curve, and celebrate with a full-screen confetti PR card you can share to Instagram. Missed a day? The makeup window repairs your streak - it never silently zeroes out.
- AI running-form analysis: film a short clip from the side and get a diagnosis - on-device skeleton tracking measures your knee angle, trunk lean, and hip drop, then cloud AI returns 3 strengths and 3 fixes. If the network fails, the on-device report still answers. Free users get 1 analysis per week.
- Ask a coach: ask anything about your training - pacing, heat, recovery, your plan. Answers are unlimited.
- Parent weekly reports: every Sunday at 7 PM, parents get a read-only report card - workouts completed, new PRs, and streak - shared via iCloud family sharing with zero setup. Heart-rate details stay private.
- Meet-day checklist: nutrition, sleep, equipment, and warm-up lists that appear automatically in race week.
- Syncs across devices with iCloud. Optional resting heart rate from Apple Health via HealthKit. Daily plan reminders. Contact support right from the app.
BRING YOUR OWN AI KEY (optional): add an API key from any compatible provider in Settings and every AI feature becomes unlimited.
