Estimate only — real results depend on course, weather, terrain, fatigue, transitions, equipment, nutrition and event rules. Not medical or coaching advice.
How to use this calculator
- Pick a brick preset (or Custom).
- Enter your bike speed and run pace to get the total workout time and splits.
How it works
A brick is a bike leg followed immediately by a run. Bike = (distance ÷ speed) × 3600; run = distance × pace per km; plus the transition.
Worked example
Sprint brick. 20 km bike @ 32 km/h + 5 km run @ 5:30/km + transition.
Tips
- Times are estimates only — not medical or coaching advice. Always train safely and follow event rules.
- Distances are editable: choose “Custom…” to enter your own course lengths.
