I found it tough too but had a hard week with IRL and Zwift rides. I did it on the last couple of days of this training block so was pretty fatigued. As a punishment for finding it hard i did AdZ the next day to really finish my legs off!!
I got a week of easy riding now so no workouts planned. Then i’ll be trying to fit in ZA with WTRL Tuesday night races and some IRL stuff. The next few weeks is going to be interesting.
