Podcast 626 - IM Wales Champion Darbi Roberts and Big Swimming with Mike Derksen

(Photo credit:

Join me for a detailed chat with pro triathlete Darbi Roberts on how she used better fat metabolism to win Ironman Wales on just 100 calories per hour!  We discuss her daily diet, training and racing strategies, and how she handles racing while working full time as an Assistant Dean at Columbia University.

Joining in for the second interview of the show is Michael Derksen.  We talk about strategies for his (and maybe your) next big open water swimming race.

Then we dive into some audio from a kids triathlon in Galveston where they swam in a water park's "lazy river."  After that, some thoughts on getting triathlon done while trying to adult and help out on Boy Scout campouts.



Episode 625 - The Science of Speed

Should you run latex tubes? Are flat pedals actually faster than clip-ins? That and much more answered on this episode!

Here's a great article that does a critical analysis of the video.

Pic of the latex tubes I usually use.

A pic of the flat pedals I bought and have been using with a ton of success lately.  Harriers from Merlin Cyclery.



Episode 624 - Ironman Canada and Youth Nationals in Ohio

Review of my favorite Ironman so far, fun prerace audio, interview with 11 year-old female state cycling champion, audio at Youth Nationals in Ohio.

 And here's a smattering of just some of the images and videos we talk about in the show.  Enjoy!

Great pic from on top of Whistler.

Episode 623 - Ironman Canada Build and Tips!

Why was there a long break between shows?  Because peak training for Ironman Canada is a huge time suck!  This episode is chock full of what it takes to get the training done, how to set your bike up for a race, triathlon news, and how to train by numbers for more clarity and simplicity in your life.

By the way, here's the super cool trainer that makes no noise and uses magnets for resistance.  No tire wear, silent, and lightweight?  Sign me up!

Enjoy the show and stay tuned for the full Ironman Canada experience next episode.  It's going to be EPIC!
