Store description excerpt
YOUR RACE DAY, WORKED OUT IN ADVANCE Training is hard enough. MarathonOS keeps the countdown, travel details, checklists, pacing, fueling, weather, race-day updates, and post-race notes in one place. TODAY'S BRIEF Open the app and see what needs attention now: days to go, key dates, preparation progress, race-day weather, your next checklist item, fuel plan, and goal verdict. KNOW WHERE YOU STAND Import runs automatically from Strava, Garmin, or Apple Health. MarathonOS turns them into a clear readiness score, training-load trends, heart-rate zones, a training heatmap, route history, and race predictions. Set a goal time to see an honest range, your late-run fade, and what could move the verdict. PLAN YOUR PACE AND FUEL Build a mile-by-mile or kilometer-by-kilometer pace band from your goal, distance, and strategy. Add a fueling timeline so every gel, drink, and timing cue is decided before the start. KEEP EVERY DETAIL TOGETHER Track flights, hotels, parking, bib pickup, expo hours, start-line directions, and other key dates. Build reusable checklists for gear, nutrition, travel, and race morning, with due dates that keep preparation moving. RACE DAY ON YOUR HOME AND LOCK SCREEN See your next race in a Home Screen widget. Follow the final countdown from the Lock Screen, Live Activity, and Dynamic Island, with weather, checklist progress, and a start-line wearable reminder visible when you need them. REMEMBER THE WHOLE RACE Save your result, splits, route, race-day conditions, notes, and what you would change next time. Race history keeps every finish and reflection together across seasons. YOUR FIRST RACE, FULLY UNLOCKED Creating races and connecting wearables are free. For the first race you add, unlimited checklists, travel and logistics, and that race's report are all included at no cost. Premium adds fueling, pace bands, goal analysis, advanced readiness analytics, and unlimited checklists, logistics and race reports across every race. Choose $5.99 monthly or $39.99 annually, each with a 7-day free trial. Prefer one race cycle? Race Block provides 20 weeks of premium access for $24.99. Readiness scores, predictions, and goal analysis are informational and are not medical advice or a substitute for a coach.
