Bike speed to finish-time calculator
Turn an average speed into a bike split — or find the speed you need to hit a target.
Average speed is an output, not a plan
On a flat, calm course your average speed tracks your effort closely. Add hills and your average drops even at the same power; add a headwind and it drops further. That is why pacing by power or perceived effort beats pacing by speed. To see how a specific course bends your average — and what it does to your run — build a Race Blueprint.
