Train smarter. Run faster. Speed Lab is the science-backed youth athletic training app built by coaches in Fairfield, Connecticut — designed specifically for athletes ages 11–18 who want real results. Whether your athlete is chasing a faster 400m, building the aerobic engine for cross country, or developing explosive speed for lacrosse and football, Speed Lab builds a personalized training plan around their unique physiology — not a generic one-size-fits-all program. TWO PROGRAMS. ONE MISSION. Distance Program — Built for middle and long-distance runners competing at the 400m through 3200m. Every workout is calibrated to your athlete's training zones, anchored to their actual race times. No guesswork. No wasted miles. Speed & Agility Program — Designed for multi-sport athletes who need to get faster on the field, in the gym, and off the line. Sprint mechanics, agility ladders, explosive starts, and power development — structured into a progressive training block. HOW IT WORKS 1. Athlete Intake — Complete a short survey with current race times, sport, and training availability. The app calculates five personalized training zones from your data. 2. Know Your Zones — Every workout is built around your zones: Recovery, Aerobic Base, Tempo, Threshold, and VO2 Max. Each zone has a specific pace range tuned to your athlete, not population averages. 3. Daily Workouts — Open the app and see today's workout. Each session includes full set-by-set breakdowns with distance, pace target, zone color, and rest. 4. Race Predictions — Based on your training data, Speed Lab generates realistic race time predictions for 400m, 800m, 1600m, and 3200m — updated as your athlete improves. 5. Track Your PRs — Log personal records directly in the app. Every PR is stored with date and meet name. FOR PARENTS — Speed Lab keeps parents informed and in control. You'll see your athlete's training plan, zone assignments, workout history, and progress — all in one place.
