CdA or Power? Where should I attack?

When attacking in a race, you need every Watt possible optimized to create maximum distance between you and your competitors.

The myWindsock resistance chart shows you each force acting against you and it’s proportions when moving forward.

On a ride, the limiting factor on your speed is the fact that your power is equal to resistances against you. Choosing areas in yellow means high acceleration opportunity, so this is a good place to attack as other resistances are lower here and not a limiting factor.

Areas with high proportions of blue show that wind and air resistance is a strong limiting factor so CdA is particularly important here. The reverse goes for areas with low amounts of blue – CdA isn’t as important here as air resistance is lower, so it might be better for you to get out of the saddle here and just focus on getting the power out.
