Ultramarathon runner and low-carb endurance athlete Timothy Allen Olson is our guest today in Episode 642 of The Livin’ La Vida Low-Carb Show with Jimmy Moore!

We've often heard within the context of endurance athletics that you must be consuming copious amounts of carbohydrates in your diet in order to adequately fuel your performance. But what would happen if an athlete decided to shift his training from being a sugar-burner to a fat-burner using ketones for fuel instead? That's what marathon runner Timothy Allen Oson from the "Sole To Soul Rhythm" blog decided to put to the test after experiencing stomach pain during his races. We'll talk with him more about this in the primary interview in today's podcast.

But first, we wanted to share about an exciting new research endeavor that we think YOU should be a part of. It's called The American Gut Project and it's the world's LARGEST open-source, community driven effort to characterize the microbial diversity of the American public. In a brief conversation with Jimmy, Human Food Project Founder Jeff Leach shares about why it's important to learn more about the microbes in your gut, his desire for a wide diversity in stool samples from Paleo, low-carbers, vegans and even SAD diet eaters, the need to raise $400,000 to pay for the expenses of conducing this research and the differences that will be seen between gut biota with people in various places around the world. This is a critically important project that we hope all of "The Livin' La Vida Low-Carb Show" podcast listeners will participate in, so CLICK HERE to join Jimmy and Christine in finding out what's in your gut!

After coming in sixth place in the 2011 Western States 100-mile Endurance Run when he went through an excruciating stretch of running that had him stop to go to the bathroom over 20 times towards the end of the race, Timothy knew he needed to make a change. So he cut the gluten and then most of the carbohydrates out of his diet that helped him experience some remarkable improvements in the stomach pain as well as in his training. When the 2012 Western States 100 rolled around in June 2012, Timothy was ready to take on this challenge of running such a long race in a mostly-ketogenic state. What happened? Well, Tim not only came in first place to win the race, but he did it in a record time of 14:46:44--21 minutes faster than the previous course best!

Listen in as Jimmy and Timothy talk about how he has always had a passion for running, the interest he got in learning more about nutritional performance due to his own physical challenges, why "carb-loading" is still so popular amongst his fellow endurance athletes, why he chooses to eat a high-fat, low-carb diet to be in a ketogenic state, his historic win at the 2012 Western States 100 ultramarathon, how a late-race challenge from one of his fellow competitors pushed him to finish strong, what he did to avoid "bonking" during the race, his new sponsors giving him the freedom to race in places like New Zealand in 2013 and so much more. You've heard about this ketogenic diet marathon runner, now hear directly from the man himself in his own words in today's interview.
