4th postgrad run today and severe pain in right calf around 26 mins. Not a particularly different route or speed than usual. Slowed to a walk as soon as it happened but still sore on walking 10 hours later and tender mid calf. No bruise/swelling and Achilles seems ok.
Will be taking it easy over the weekend but is it best to wait until completely back to normal before heading out again, or reduce to shorter runs for a while?
