As training for the MoonWalk on June 16th, my teammates and I walked from Cramond to Musselburgh on Saturday. It took just over three hours and afterwards we treated ourselves a delicious lunch of cheeseburgers and ice cream sundaes at Luca's in Musselburgh. Surprisingly, it wasn't all that difficult and, although I was knackered on Saturday evening, I'm not even sore today. Fantastic! More long-distance walking to come in a couple of weeks.
Addendum: Oddly enough, I got sunburnt only on the right side of my face and neck. We were walking more or less directly west to east along the coast, so my right side was directed south for three hours from 11am to 2pm, but I never realised it would make such a noticeable difference when it came to UV exposure. Weird.
