So you're feeling like 61 more so than 16? I know that feeling What I used to do all day long now takes me all day long to do! Hard as it probably is to believe today, this too shall pass!
I know it will but I really wish I had started doing mud runs in my teens or twentys, not waited till my late 40's. I bounced back a lot faster back then...
The good/bad news is I have 2 more mud runs scheduled in the next month or so....I think I can extend the pain all the way till May.
