Rim brakes are working well! But, I have worn the brake tracks down a fair bit. I bought a new rear wheel last week.
I swapped Wednesday & Friday this week because of time constraints on Wednesday, so I did VO2 instead. It was Very Hard.
Edit to add: Thursday morning was raining so instead of the bike workout I went to the gym on the way to work for weights, then got home & didn’t feel like a bike workout. Stayed up too late (was probably on here 
), too tired Friday morning, brain-fried from work on Friday afternoon. Tsk tsk. So skipping on Friday was my own fault.
