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.

resistance

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.

After that KOM, Course Record or a new PB?

Everyone wants to be the best athlete that they can be and get the fastest times they can possibly achieve.

But do you ever feel that you’d perform so much better if you didn’t have to battle a headwind?

Well… what if i told you, you don’t have to battle that pesky headwind!

With segment windsocks, you can choose a Strava segment that you would like to target and be informed when is the ultimate time to attack.

 

So how do you do this?

  1. Simply set the bell on the segment windsock

Almost late for work

I ride back and fourth between work and home quite regularly. On paper, the way out should be easiest with only 97m elevation compared to the way home being 108m elevation. So why did the way out feel so hard??

On the way there I had 89% headwind!!! This gave me a feels like elevation of 170m. Without knowing it, I had climbed up mow cop, our local climb (150m).
On the way home I had only 14% headwind, meaning 86% tailwind making the 108m elevation only feel like 93m elevation!

Looking at the wind impact is quite amazing on out and back journeys because if you’re going straight into headwind it has a massive effect! I’ve done the journey before and it’s taking me 33 minutes with a relatively easy effort but it took me 50 minutes with the headwind as it was today!

Luckily I wasn’t late to work but I did cut it close!
