Oh dear that was horrible.
I held on for lap one, then fell off as soon as I tried to drink. ftp boost to 329 so was putting the effort in at least.
Finding pace was really awkward. I’d be in the pack at 300-350w then suddenly leap off the front and stay there at 250w before being spat out the back at 400.
Then I’d end up getting the wrong draft as we passed someone and needing to pull 600w to get back on.
Could barely hold 200w going into lap two. About half way round put my head down to take a deep breath thinking of getting off and spotted my axle was completely undone so the bike was wobbling everywhere. Got a lot easier to hold a normal effort after I tightened that 🙁.
