Muscle memory. I would go through the same thing transitioning to the next seasons sport in high school. I thought because I played basketball for 2 hours a day that lacrosse practice would be easy because I was already in shape. Nope. First week I was destroyed. If you ran regularly outside and then did the 10k it will be easier.
Btw you’re in great shape already. Please be kind to yourself 😀
