Well, the dreaded calf leg cramp in the middle of the night struck me again last night. Not so frightening for me, but when you share a bed with someone and wake up basically screaming, I imagine that is quite frightening. Any way after that happened I reset my alarm for 7:30am as I knew my leg would be too sore to run the 10k this morning (from experience) How common is this sleeping cramp and what causes it? I don’t know but my leg is sure sore this morning and I have been doing a few stretches to try and get it right for another evening run…not after a big dinner though. Will post again after that.
