Live GPS recorder on the phone, unlimited Garmin sync. Follow a planned workout with audio cues, or just press start.
One platform for runners and endurance athletes. GPS recorder, Garmin sync, plan builder, AI coach, strength log, social feed — in a single account. Designed with restraint, so the only thing asking for your attention is the next run.
Most athletes pay for a tracker, a calendar, a coach, a social feed, a strength app. Four tabs, four logins, four subscriptions — and not one of them aware of the others. SPLIT replaces that stack with a single account whose only job is to understand your week.
Live GPS recorder, Garmin sync, plan builder, AI coach, strength log, route builder, friend feed, challenges, race predictor.
Premium is $8/month (or $80/year). Below the monthly price of almost any single piece of the stack you’re probably running today.
Held on European servers. Bulk export to CSV or JSON whenever you ask. No upsells that lock your history.
Periodised by VDOT, FTP, or CSS. Recovery-aware. Sport-specific engines — not a running plan with a different label.
Live GPS recorder on the phone, unlimited Garmin sync. Follow a planned workout with audio cues, or just press start.
VDOT, lactate threshold, HR zones, pace trends, race predictions. Every session auto-analysed with rules-based feedback.
Follow other athletes, see their runs, comment on routes, drop a kudos. Unlimited feed on the free tier.
Weekly distance or elevation challenges, group streaks, leaderboards. Create your own for Premium; join any at no cost.
Ask training questions in plain English, get narrative answers tied to your actual data. Deep narrative on every Premium run.
Pick a sport. Pick a race. The plan builder generates a periodised schedule and pushes it to your Garmin calendar.
SPLIT started as Mark’s personal training dashboard on the road to a sub-80 Copenhagen Half Marathon. It grew into a full platform once the core engine proved it could actually help someone hit a real race goal.
