This week on the InnerFight Endurance Podcast, Rob and Dan Bagley dive into the latest running news and training insights. They break down Adidas’ ambitious 100K project and the attempt to crack six hours, the addition of Kipchoge and Sifan Hassan to the 2025 New York City Marathon, and new Strava–UTMB data showing the rapid growth of trail running worldwide.

Dan also shares his buildup to the Berlin Marathon, including how he’s adapted training in Dubai’s summer heat, the role of treadmill sessions, and the mental lessons he’s learned along the way. Finally, in their “Clear It Up” series, Rob and Dan unpack one of the most misunderstood training terms in running: tempo running. What it really means, how it differs from threshold training, and how everyday runners can use it to improve.

Whether you’re chasing a PB, exploring trail running, or just trying to understand the science behind the jargon, this episode has you covered.
