I skipped a run midweek, had fish and chips last night, washed down with beer and followed by ice-cream. Then I ran a Parkrun PB this morning, 26:13. Madness!
Of course, that't not the entire story. I faithfully followed the C25K programme and I've really been pushing myself since week 7. It was a small fish and chips and 3 small beers plus a small scoop of ice-cream. The midweek run was only skipped due to sore knees and I've been eating a lot more healthily for weeks. Just goes to show that if you stick at it then it's okay to ease off a bit sometimes. .
Good luck if you're running this weekend. Onward and upward.
