Tiredness

[El Gordo]

It's common to feel that way the day after a long run, less so after a rest day. Apart from 'a night on the grog', the usual explanations for me are lack of sleep or eating badly. After a cornish pastie and chips for lunch and a few bars of chocolate through the afternoon, I rarely feel like a good run in the evening....

More seriously, yes, it does happen Miss C. Just one of those inexplicables, though certainly your afternoon in the pub may well have taken a day or two to work its way through the system.
