What this guy (David Roche) did is absolutely amazing and counterintuitive. He's not an ultramarathoner, yet he demolished the record for running the Leadville 100 race on 18 Aug 2024. He touches on so many aspects we've all talked about WRT training. They even refer to cycling and the TdF during this interview.

It' a very long interview, so you may want to cut it up and view it in sections, but it's very interesting and much of it is out-of-the-box thinking.

BTW, he employed a very high amount of speed training to prepare for this race.
