MarathonOS: For All Runners

Train. Plan. Race. Remember.

Features & Capabilities

Now you can view all training runs for an upcoming or finished race in one place, along with an improved onboarding experience — so you can start preparing even sooner!

YOUR MARATHON COMMAND CENTER

From registration to finish line to years of racing memories.

MarathonOS is the only app built for the full marathon (and any race really) experience. It's not a training app or a run tracker. It's the home for your entire racing life.

RACE DAY COMMAND CENTER: Countdown to race day. Upcoming race details, recent activity, weekly stats -- all on one dashboard. Open the app and know exactly where you stand.

RACE DAY LOGISTICS: Flights, hotels, parking, bib pickup, start line directions -- everything in one place. No more digging through emails the night before. Never show up unprepared again.

SMART CHECKLISTS: Gear, nutrition, travel, mental prep. Customizable lists with due dates so nothing gets left behind. Never forget your race belt again.

YOUR MARATHON MEMORY: Pre-race notes. Post-race reflections with mood, effort, and weather. Mile splits. What worked, what didn't. Build your personal marathon knowledge base that grows with every race you run.

PROVEN TRAINING PLANS: Four battle-tested methodologies built in -- Fatigue First and Build Then Sharpen. Link plans directly to your race with calendar sync.

TRAINING ANALYTICS: Race predictions, readiness score, heart rate zone analysis, training load tracking, workout grades, split consistency grading, and an activity heatmap -- all in a swipeable analytics carousel.

CONNECT YOUR WEARABLES: Strava, Garmin, and Apple Health. More options to come. Auto-import your runs. New activities sync within minutes.

Built for the long run. Free to use. Premium unlocks advanced plans, full analytics, unlimited checklists, and complete race logistics for the price of 2 gels or $5.99/month or $39.99/year.
