Quarantine fitness

Nah, I only had 3 cans and two of those were probably sweated out on the turbo. I think it's much more likely a case of the watts used in the Zwift race. The only time in the last 10 years I'd see >450W on my PM is a badly paced 10mi TT where I have the energy for a finish 'sprint' or the 1000W spikes when dogs would suddenly appear in Kentucky (TABR) or Romania (TCR).

I have a sore lower back and that's almost certainly from the Zwift race. I get the same kind of dull ache when wrestling too high a gear up steeper climbs.
