Spoke too soon

Because today's run was horrible. I did have a hangover which didn't help - I am going to have to massively cut back on the alcohol if I want to make this work. I did 1 x 20 min run with a short walk break (and loo break - note to self, the Crown and Greyhound only has hot water in the ladies, disgusting to drink) then another 10 minutes - it was meant to be 20 but I just ran out of energy. I think it's also partly in my head - my chest wasn't aching and my legs felt fine, I just felt blergh. I also then had a mammoth walk home from North Dulwich as I'd run so far out of the way. Better luck next time...
