I wouldn't even bother to get changed for 15km haha.
Moving time was an hour and ten minutes, I had waterproof overshoes, waterproof trousers, OG winter jersey and RCC brevet gilet. Oh, and some Fox gloves. Felt about right tbh, and the piece of cake was nice.
Smashed out another 15km today, I think I've got this DNF locked in.
