We have been working on controlling the controllables and not getting stressed about the things you can’t control. What if it pours with rain on race day? There is NOTHING you can do to prevent that, but you can control your reaction to the conditions – think about your clothing choices, test out all the potential kit you might use so you are comfortable with whatever you need on the big day.
What if you get a puncture? Bloody annoying. Easy to allow something like that to derail your race, but there is no point getting stressed about the possibility. Much better to think about how you would react in a race situation and, if needs be, practice.
