How to use
- Enter the inputs.
- Sanity-check the outputs.
- Use the result as a planning anchor, not a promise.

Quick answers
The 60-second version
Snippet-ready answers to common questions. Use the calculator above for the numbers.
What should I optimize first?
Consistency on the run segments and one station weak point. Small station improvements compound across 8 stations.
How should I pace the first half?
Conservatively. The first 2–3 stations should feel controlled so you can execute late under fatigue.
Why do predictions miss?
Stations degrade under fatigue and transitions expand with crowding. Use the estimate as a planning baseline, not a promise.
Assumptions
What this tool assumes
- • Your average station time is a realistic in-race number (fatigue increases station variance).
- • Transitions are consistent (crowding can change this dramatically).
Limitations
What can break it
- • Does not model station-specific weak points (sled push/pull often dominates outcomes).
- • Race flow (heat size, venue layout) can add unexpected transition time.
