Spent most of yesterday (Friday) in bed. The highest outside temperature for the whole day was 8°C but with 15 kph winds the chill factor was nasty. I got up for meal/toilet breaks. Much of my trouble was from major leg cramps, some episodes going for five minutes at a time. My thigh and calf muscles are still quite tense afterwards. It's now 8:30 am on Saturday and I've been cramp-free for about 10 hours.
