The last time I competed, I carried two bottles of fresh water.
The night before the race, Mom did a big steak and kidney pie, mash and peas; with trifle to follow.
The morning before the race, I had two weetabix, some toast and marmalade; and the remains of the trifle.
It was a fantastic day. I didn't win. The winner's Mom knew how to make Bolognaise sauce.
