Why wear WHOOP 4.0

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.

Training on a non-electric cargo bike! The kids love it! No need for fancy GARMIN head units: WHOOP can track your workouts on any vehicle.

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!

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

... as a trained cyclist this ride data is not good: heart rate of 180BPM at an average speed of 22KM/h - this is 'the COVID effect' on my body - MISERABLE DELUXE
