Worked example

Worked example

A 21097m time of 1:45:00 is an average split of 2:29.3, which is 105.1 watts at an even pace.

How it is worked out

The average split is the time scaled to a 500m split: split = time × 500 ÷ 21097. Watts then come from that average split: watts equal 2.80 divided by (split ÷ 500) cubed. The figures assume the same pace over the whole distance. They show what a time needs, not a pacing plan.
