It's always a gamble, entering a big endurance event. Months of work and build up, all for one day. It is all consuming, every weekend gets taken up with a training epic or practise race. Holidays get planned around good training locations. Toenails gradually disappear. Life becomes divided in "before and after", where "after" is really the only suitable time for hardcore socials as it won't interfere with training. Money gets spent fine-tuning your bike (okay, getting bar tape that matches your frame and helmet..) whilst your car gets abandoned and no matter which bag you go to, there will be some sort of energy bar in it, just in case.
