Rise and shine.
Get up at least three hours before the start so you have time to eat, drink, and use the bathroom. Aim to be at the starting area at least an hour in advance – earlier if it’s a large race – to get your bearings and use the bathroom again.
Get in line.
Once at the race, line up for a portaloo, even if you don’t need to go. Nature may call by the time you get to the front. Head into the starting pen 15 minutes before go-time – you may be required to line up sooner at a large event.
