Can you imagine visiting all 59 US national parks in the span of just over a year? Now how about running a full marathon in each one of them? When I first heard about Bill Sycalik's Running the Parks project, where he will run 59 marathons in 59 national parks, I knew he was the kind of guy I'd want to talk to. Bill set off last June to run in each national park in the United States. Eleven months later and he's already checked off 41 marathons. In today's episode of Trail Talk, Bill shares the motivation behind his project, how to logistically plan such a massive trip, and what all that running has taught him about gear, locating trails, safety, and rapid recovery.
