This week's question was emailed by Martin, who's just realised that his first marathon of the year is six days after St George's Day. Which involves loads of beer. Any thoughts?
Advice from coaches and medical types especially welcome...
"How much harm will a skinful of ale a week before a marathon do me? I'm running my first full marathon of the year on Sunday 29 April, six days after St George's Day. St George's Day means a pressing engagement with a succession of public houses, and drinking loads of beer is a really key part of it. I won't be training much in the week before a marathon anyway, and the alcohol should be gone from my system by mid-week, so will my skinful do my marathon prep serious harm?"
