Tracking
Live GPS recorder, 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.
Most athletes pay for a tracker, then a calendar, then a coach, then a social feed, then a strength app. Four tabs, four subscriptions, none of them talking to each other. SPLIT replaces the whole stack with a single account that actually plans your week off your real data.
The platform is built for runners and endurance athletes who want real data, real coaching, and a tool that helps them improve — not another dashboard that looks handsome and ships nothing to the watch. Every number has a mechanism behind it; every chart has a calculation you can audit.
Live GPS recorder, Garmin sync, plan builder, AI coach, strength log, route builder, friend feed, challenges, race predictor.
Premium is $8 a month, or $80 a year. Below the monthly price of almost any single piece of the stack you’re probably running today.
European servers. Bulk export to CSV and JSON. No upsells that lock your history.
Adjusted for VDOT, FTP, or CSS. Recovery-aware. Sport-specific engines, not a running plan under a different label.
Live GPS recorder, unlimited Garmin sync. Follow a planned workout with audio cues, or just press start.

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.

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.
