Yes, the podcast is geared towards ultra runners, however, there are a tonne of podcasts on there suitable for anyone doing Iron distance races as well. I went through 20 of them on a recent trip and can't wait to hear the rest of them.

I have 0 affiliation with the podcast, just thought this would be great for lots of folks here who may need a little more science in their training.
