Evver have those rides...
...that make you realise you're actually not a cyclist, just a guy with a nice bike? Had one this morning, climbing up the steepest hill I've seen for a long time, at the mid-point I got a horrible cramp in the right hamstring. I had to get off the bike to stretch it out and found myself sitting in the gutter, trying not to vomit.
Not my most dignified day. Awesome with hindsight, but not at the time.
