Not today but yesterday saw me take a spin on my fixer from my place to Tooting, so they could take some of my platelets. 30 miles which, if Strava is to be believed, took me 2:09 elapsed. That's surprisinly fast for me, given there's an amount of suburban traffic involved too.
"Have you done anything strenuous today?" they ask when I check in, with a similar warning when I leave. I didn't think it was strenuous, but I was bollocksed on the way back. I tried to get to Epsom in time for a train for the latter part of the ride but missed it by a few minutes. I waited the next, which got me to Dorking, then I cycled the last 20km. Stuff me, they were full value, crawling up the hills like an old git, swearing at the close passing cars on the A24, happier on the lanes, even happier to get home.
