Just as I was falling asleep last night I woke myself (and my husband) up with the worst cramp ever, all down the back of one thigh. It took what felt like a lifetime of sweating and whimpering in pain before I could straighten the leg and stop the cramp springing up again & the leg's still pretty tender now.
In retrospect this may be due to a week of unaccustomed fine weather leading to too much digging in the garden, as well as my usual cycling (I'd done about 20 miles - which is a bit more than usual but nothing out of the ordinary) and probably a bit of dehydration. I tend to cycle for transport, in my normal clothes, averaging about 10mph so I've never thought of what I do as exercise requiring stretching, isotonic drinks and all that malarkey but I suppose my leg muscles don't know that...
Assuming this is a (literal) wake up call from my body what would you say is the cut-off between just getting somewhere on a bike and the sort of exercise that requires taking it seriously enough to rehydrate, stretch, warm up and all of that stuff? And are there any good 'normal' drinks for rehydration? I don't want to spend huge amounts on some nasty-looking sports drink if it turns out lemon squash (or Guinness) will do as well.
