Spent a lot of time working on the calf beforehand, including taking some mineral supplements as recommended by Colm. Still hurt before I started but amazingly was pretty much OK while running, though quite sore again as soon as I stopped.
Wasn't really prepared to actually be able to run today, and kept expecting to have to stop, but surprisingly managed to pretty much hold it together. But very, very slow. Think it was a combination of the heat and the usual jetlag issues, but I felt worse at the end of this than I can remember feeling at the end of a race for a long time, and I wasn't even making any attempt to race - just plodding round. Lost 20sec at 19 (didn't see the pit as I ran down the spur) but otherwise clean.
The calf injury appears to be a combination of ongoing cramps having lead to one or more tears.
