Mikael Eriksson and Jack Hutchens answer listener questions, starting with a long look at how to fit a marathon into a triathlon year: when to do it, how much running it takes, what happens to the swim and the bike, and how far the long run really should be. Then questions on racing a 70.3 inside a base phase, coming back from overtraining syndrome, and whether you have to dig a hole to get supercompensation.We do listener Q&As monthly, the last Thursday every month.
