I'm in the early stages of thinking about doing a round next year. I reckon I've got a good base to build on, having run ultras for the past few years, so am not too worried about the physical challenge, but am concerned by the amount of time I'm going to need to spend away from the family in what is essentially a selfish pursuit of my goals. How much time is realistically required to reccie the route, help support others in order to get experience and build a network of potential supporters, and get the necessary climbing and time on feet in that will be needed? How have others negotiated this with their non-running families?
