My Grandmother-in law found out that I'm cycling from Bilbao to San Sebastian tomorrow and prepared a potato salad big enough for about six people. She said that "that's what they used to eat years ago".
Maybe in the fifties.
I showed her the dazzling array of electrolyte tablets and other brightly-coloured supplements that I'd be consuming over the course of the day, but she was having none of it. I think I might have just ruptured something getting into bed.
I hope you have fun Paul!
