One platform. One bill. All yours.

Your training stack, finally under one roof.

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.

  • Everything in one place. Live GPS recorder, Garmin sync, training plan generator, AI coach, strength log, route builder, friend feed, challenges, race predictor. No more tab-switching mid-workout.
  • Less than any single tool you’re paying for. Premium is $8/month (or $80/year). That’s below the monthly price of almost any single piece of the stack you’re probably running today. 60-day full-feature trial. No card required.
  • Your data belongs to you. Hosted on European servers. Full bulk export to CSV/JSON whenever you want. No upsells that lock historical data behind a paywall. Delete your account and everything goes with it.
  • Plans that read your training, not just the calendar. The plan builder adjusts to your VDOT / FTP / CSS, your recovery trend, your A-race taper, and your registered B-races. Running, cycling, swimming, triathlon, and strength each have their own engine — not a running plan with a different label.

What you get

SPLIT is built for runners and endurance athletes who want real data, real coaching, and a platform that actually helps them improve.

Tracking

Live GPS recorder on the phone plus unlimited Garmin sync. Follow a planned workout with audio cues, or just press start.

Analyze

VDOT, lactate threshold, HR zones, pace trends, race predictions. Every session auto-analysed with rules-based coaching feedback.

Connect

Follow other athletes, see their runs, comment on routes, drop a kudos. Unlimited feed on the free tier — the engagement loop is frictionless by design.

Challenge

Weekly distance or elevation challenges, group streaks, leaderboards. Create your own for Premium; join any at no cost.

AI Coach

Ask training questions in plain English, get narrative answers tied to your actual data. Premium unlocks deep narrative on every run.

Planning

Pick a sport. Pick a race. The plan builder generates a periodised schedule and pushes it to your Garmin calendar.

Built for athletes

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.

Simple pricing

Core tracking stays free forever. Unlock the coach, full history, and cross-device push with Premium.
