I'd been somewhat concerned for some time about the state of the bike frame mounted on my Tacx Neo trainer - many years of heavy sweating had corroded it really badly. I had joked recently about it collapsing, and had obtained a replacement. But of course as I awaited parts to arrive, I hadn't set it up.
I completed a decent 40 minute warmup pretty well, though I'd noticed that the gears were sounding a bit rough, and occasionally the rear mech seemed to want to change on its own accord. Oh well, I thought, I have a look tomorrow. A few minutes before my scheduled start ay 19:04, I moved to the start pen and waited a few minutes to start.
