A week 'aff, or a weak calf?

Things took a turn for the worse on my run to the gym last night, while over-protecting my knee with a support I seemed to have strained my calf. I finished the run but was hobbling last night. This morning is better, but Sunday's Whinlatter Extreme Duathlon looks like it's not to be taken lightly, especially with run 1 being a 9km climb up to the summit of Grizedale Pike (629m) via the Sleet How Ridge. I shall travel, but may not compete. It'll be a nice trip to the Lakes anyway for a bit of camping with Nick, if nothing else.
