TRACKING
Live GPS recorder on the phone plus 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 open, 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.
Live GPS recorder, Garmin sync, training plan generator, 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.
European servers. Full bulk export to CSV/JSON. No upsells that lock historical data behind a paywall.
Periodised by your VDOT / FTP / CSS, your recovery trend, your A-race taper, your registered B-races. Sport-specific engines, not a running plan with a different label.
Live GPS recorder on the phone plus 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 coaching 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. Premium unlocks deep narrative on every 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.
