Episode Description from the Publisher

You’ve finished 50 miles, and now you can’t stop thinking about 100. But doubling the distance brings a whole new level of uncertainty. Do you need to run a 100K first? Are you really ready for 100 miles? And how do you prepare for a distance you’ve never experienced before?In this episode, I’m sharing the five things I would focus on if I were making my own leap from 50 to 100 miles again. I show you how to prepare for the challenges ahead so you can make strong decisions, adapt when things don’t go to plan, and give yourself the best chance of running a race you’re proud of. You only get one first 100, and the goal is to make it a triumphant adventure while laying a strong foundation for the 100s still to come.For full show notes, transcript PDF, and more information, visit https://susanidonnelly.com/78Connect with Susan:Instagram: instagram.com/susanidonnellyFacebook: facebook.com/susanidonnellyMentioned in this episode:Get The Ultrarunner’s Mastery Debrief Template Today!Every race gives you experience.
