Summary

First up, Matt talks with Kaʻeo Kruse from Stryd about how running data can help HYROX athletes race smarter. Kruse explains his background as a runner at Harvard and UVA before transitioning to triathlon and training with USA Triathlon in Boulder.

Using Matt's race at HYROX Phoenix as a case study, they break down pacing, cadence, stride length, and running power. The data showed how maintaining consistent effort led to a five-minute improvement and why even small efficiency gains can make a big difference in HYROX racing.

In the second half of the episode, Matt catches up with Chad Trammell and Lars Arneson from Anchorage, Alaska. Trammell reflects on winning World's Toughest Mudder and the early days of obstacle racing, while Arneson talks about his background as a Nordic skier and mountain runner.

The pair recently finished fourth in Pro Doubles at HYROX Phoenix with a time of 50:41, despite only doing a handful of strength workouts together. They break down their race strategy, where they lost time, and whether they'll pursue the Elite 15 Doubles races moving forward.
