Achilles heel

This week our Sunday run took as along the Yarra river.  The conditions were quite humid so I started sweating earlier than normal and by the time I had finished I was completed drenched.  I've been quite tight in the achilles for the last week or so and that tightness turned into soreness on the way home.  I don't think it's too serious so with a bit of ice and stretching I'll should be fine.
