Went to get a gait analysis and new trainers (graduation present to myself).
Jumped on the treadmill - tried on different trainers, and while I was on the fourth pair - snap - something happened in my right calf muscle. And it hurt. Like hell. Ouch!
Didn't tell the nice sales person about it - just bought the best trainers (same as yours, Pushing60, nice ones!) and hurried home on my bicycle and iced the muscle for a while.
It's been 9 hours now, and it's still bloody painful, but it's getting better.
Perhaps my vacation in Greece won't be a running adventure after all.
Right now I'm feeling really stupid and sorry for myself but I'm sure tomorrow when I see Greece from above, I'll be alright again.
