I had the pleasure of being the guest on the latest episode of Mikael Eriksson’s That Triathlon Show, a podcast focused on the science of everything endurance-related. Regular listeners will remember that I went on this same podcast back in June to chat about the intersection of physiology and training, and it was great to come back on the show.
This time, Mikael and I went in-depth on the modern approach to marathon training that I lay out in my new book, Marathon Excellence for Everyone. We talk about periodization, mileage, workout progression, structuring your weekly schedule, and what most runners get wrong about marathon training.
We also do some Q&A from listeners on LT1 (the first lactate threshold), double threshold vs. special blocks, heat training, and more. I love doing technical deep-dives like this, so this show was incredibly fun.

As always, it is very helpful for podcasters if you leave a review on Apple or Spotify, and share the episode with friends who might enjoy it.
Hope you enjoy the show!

Hey John - any timeline on the Kindle and Metric versions of the book?
Metric version should be done by late October / early November! I'm done with basically everything except the training plans already. Kindle version I'm less certain - depends how easy or hard it is to convert the physical layout book into an ebook. Some of the figures/tables could be tricky, we'll see!
