Perhaps I ran a too early

I feel worse today than I did yesterday. Could last night’s run be the reason?

As a result I skipped my planned run and swim today. Instead I used my stairs for theie alternate purpose and did a set of chin-ups:

1,2,3,4,5,6,7,6,5,4,3,2,2,1

Why the 2,2,1 at the end? To reach 50 of course!
