A Deep Dive into My WHOOP Data During the Fietselfstedentocht 2023

May 31, 2023 - Willem L. Middelkoop

This Monday I completed 235KM on my fixed gear bike during the Fietselfstedentocht 2023. It was a nice ride with fair weather and favourable wind conditions. Yet, I took the challenge seriously and prepared myself with some proper training. In this post I'll have a look at the trend data from my WHOOP in preparation for the Elfstedentocht.

The morning after WHOOP calculates the readiness of my body to take on (new) training strain - you can clearly see my body didn't recover overnight: just a 7% recovery score!

Testing positive for COVID, you don't want this when picking up the training regiment...

Training has its effects: my average HRV is trending upwards again!

Smile and keep on cycling! Eventually things DO get BETTER.

I have gained weight as I lost fitness: confirming that WHOOP is on to something: there seems to be an inverse correlation between my weight and HRV trends

My (early morning) resting heart rate is going down, too! It inversely correlates with my HRV going up. Some nights dip into the low 50's, high 40's - I am getting back into shape!
