PaceProof

PaceProof is a mobile + web app (traditional + AI) that builds realistic pacing and fueling plans for both sprints and marathons, then stress-tests them against real conditions. Users import recent runs from Garmin/Strava, enter a goal race, and the app generates a plan with target splits, cadence ranges, and “if-then” adjustments for hills, heat, wind, and crowded starts. During training, it flags when your workouts suggest your goal is too aggressive (or too conservative) and suggests a revised target with confidence bands rather than a single fantasy pace. On race day it provides an audio/visual pacing guide and a simple “I’m fading / I feel great” input to adapt the next segments. It’s not a coaching replacement; it’s a practical pacing copilot that reduces blow-ups caused by unrealistic split plans and poor mid-race decisions.
