Thanks @steevc, I was disappointed initially, but starting to feel better about it now. I think that was because I physically doing ok, but at the first sign of legs/feet being sore, I gave up mentally... deep down, I know I could have done more the following morning.

But it is what it is.

It is something I can learn from... and something I can practice, for example by doing back-to-back long runs, so I can get used to moving on tired legs.

But yes, rest now... some more !Pizza will help too I'm sure! 🍕🍕
