The question I’ve been asked most about running the 10in10 (apart from ‘why?’) is, ‘How do you train for something like that?’. It’s a great question, and it seems there is no simple answer. As the 10in10 is so different from anything else I’ve attempted, I have been keen to test myself by running marathons over multiple days and incorporating more hills into my training. The last ten days have provided the opportunity to test both of these elements out. I have run my first fell race, and then completed 3 marathons in 3 days.
