Sure, he figured out the for success (it's the if you're curious) and he credits his with saving him time on navigation, but we wanted to know what the special sauce was that powered him through the 35-day adventure so we sat down to find out how he did it, and what he learned along the way. No one would be surprised if running the equivalent of Everest 12 and a half times over the course of a month brought about a few weird side effects, but Catterall says thanks to his training and preparation, there were no nasty surprises.
