Thank you to Runna for sponsoring this series! Try Runna for FREE for two weeks: https://tr.ee/icWqec2daq In this video, I recap my recent finish at the Crazy Mountain 100-mile ultramarathon. I also discuss my next running goal: running a 2:39 at the Chicago Marathon! I'll also be running the Berlin Marathon for fun, a few weeks before Chicago. I'll be using the Runna training app to prep for these marathons, so I go over how to build a custom plan in the app. Hope you enjoy! Welcome to the 2:39 marathon prep series! On October 12, 2025 I'll be running my 14th marathon at the Chicago Marathon and aiming to run a new personal best of 2 hours and 39 minutes. In this series, I'm going to give you an inside look at my training block. From my training plan, my diet, speed workouts, strength training, training gear, how to fuel for running, and so much more. New episodes will be uploaded every Sunday at 10am CST. 💸 Discounts and Deals on Running Products: https://linktr.ee/jeremy.miller ⚡️ My electrolytes https://bit.ly/47Kyiyc 🫐 $10 off 2Before https://2before.com?sca_ref=3530967.1YZdFFfnuW 🥩 Get 15% off Frank’s Butcher Shop (JMILLER) https://franksbutchershop.com/ Follow Me Strava: https://www.strava.com/athletes/49516157 Instagram: https://www.instagram.com/jeremymille.r/ Tiktok: https://www.tiktok.com/@jeremymillerfit Website: https://www.jeremymiller.io
