Not at all as 'thorough' as this guy, but when I was back home in March for the Ballycotton 10 (miles), I very stupidly went out for a feed of pints the night before. I lost track after about 6 pints of Beamish [i:2d0eylf9](king of Irish Stouts, long live the king...) [/i:2d0eylf9]and didn't get to bed before 4am.
Luckily, the race meet was the next afternoon, but somehow, I still made my target time and a personal best for the distance.
Fuel in the tank, I say. Who knows, one of these days discovery will be made that hops-derived alpha-acids put a bounce in your step.
