How to you recover from a 20k steps + walk

[Cloud44]

Over the weekend I went for a really long walk, I regularly do 12k+ steps a day but this was over 20k+ and I still feel knackered!
AIBU to think I should feel ok now or is it normal for it to take a couple of days for feet / legs to stop aching and to have energy back?! Any tips of what I should be doing?

I do between 15 - 20 a day- I do find on the 20 days, that's my hips and lower back hurt at the end of the day. I'm 31 so not to do with age necessarily. But yeah just eat some cottage cheese and get a good sleep!

Well gosh op, I regularly walk 50 miles a day, do 3 spin classes and finish off with weight lifting and all I get is a teeny ache in my little toe.

You must be so unfit. Poor you.
