Swimming 20:00 [2] 0.5 km (40:00 / km)
The swim didn't go so well. Was having trouble with foot cramps almost from the beginning, and when I started to get calf cramps as well it was a worry - one particularly sharp one was enough to convince me enough was enough. Not sure what the problem was - there was no sign of trouble on the run, I don't think my diet this week has been unusually salt-deficient, and lack of hydration certainly hasn't been an issue. To add to the mystery, no sign of feeling untoward through the rest of the day, either.
