Power Requirements
Based on calculations from the Bicycle Power Calculator
Table 1 shows the power (watts) required to climb a 6% grade at various speeds (mph).
The riders weight = rider + bike + gear. The same standard drags and zero wind are used in all calculations.

Table 2 shows the power (watts) required to ride on a flat course at an average of 20mph and 25mph.
The riders weight = rider + bike + gear. The same standard drags and zero wind are used in all calculations.
Wind drag was calculated based on a full crouch position as this was closest
to aero-position, actual drag and therefore actual watts required,
will be less for smaller more aero riders.
