Race Planner
Stop guessing on race day. Build a precise, crew-ready strategy for every mile: aid station splits, drop bag contents, crew windows, and pacer handoffs, all in one place.
Upload your Garmin activity export and the planner predicts your aid station arrival times based on your real VO₂ max, training load, elevation history, and HR zone distribution — not a generic pace estimate.
- Personalized splits based on your race data
- Personalized drop bag recommendations based on your race data
