Marginal Gains Cycling Podcast, Presented by Silca

If you think the stories you've heard about the 2023 Unbound are crazy, wait 'til you hear Kristen Legan's story of her XL win. She focused on this race this year, and her preparation and dedication will resonate with any endurance Margingal Gainer. Kristen's joined in this episode by Nick Legan: author of the popular book Gravel Cycling, Unbound vet, top-tier mechanic, and Road Brand Manager with Shimano. Enjoy this is deep dive into bike setup, mental marginal gains and thick, sticky mud.

We take our mission of making a big deal about the little things very seriously in this episode, where we talk about whether there's any actual basis for the superstition behind where you rotate the wheel to before inflating a tire. We then move to the admittedly more pragmatic questions of how much of a draft an aero rider provides to the riders behind them, the low-hanging gains for DH racing, and the problems with racing a 1X setup on the road. And that's not even remotely close to all (even though we could have talked about each of these questions for a full hour).

For Silca’s E-commerce manager, Travis  Verhoff, the 2023 edition of Unbound has been a bit of an ongoing science project. In this episode of Marginal Gains, we dig into Travis' expectations, last-minute changes, and key learnings from this experiment...and after all is said and done, what he would change and whether he'd ever race this monster again.

You've no doubt heard Josh mention Slowtwitch.com many times on this show.  It's one of the key places he goes to share ideas and get feedback. But Slowtwitch is more than just a place. It’s a person too. The site was founded by Dan Empfield in 1999, and remains publisher to this day.  But before Slowtwitch even existed, Dan was a competitor. He did his first Triathlon in 1978 and competed in the first Ironman Kona in 1981. You may also know Dan as the man behind Quintana Roo. That stack and reach thing we all use now: that came from Dan’s work. We get into all of that and more with our guest this episode:Tri Hall of Famer, Slowtwitch founder and Publisher Dan Empfield   

It's an Ask Josh Anything episode! We talk about The Rule of 105, the extent to which "bigger is better" is true for fairings, whether tire inserts need to be factored in when using air pressure calculators, why you might get conflicting recommendations from different air pressure calculators, how many watts a slow-turning old derailleur cog might cost you, the challenges a hot day might bring to your waxed chain, and more. So much more. Some people might say too much more, but we are not those people, and we're betting you are not either. Don't miss this episode, and keep your questions coming!

Silca's own Travis Verhoff has an unusual work assignment: plan, train for, and execute the most Marginal Gain-y Unbound possible. If you've been following the Silca YouTube channel, you've been tracking his progress. In this episode, we catch up with his bike setup, key learnings and surprises from time in the wind tunnel, using the Chung method on course to select tire pressure just days before the race, his nutrition, and a lot more. If you're a nerd about Marginal Gains (and we know you are), do not miss this episode about putting theory into practice.

Amanda Nauman has one of the most disarming nicknames in all of cycling: she is affectionately known as Panda. But make no mistake: behind the woman named after a docile creature is a fearless person, both on and off the bike. Amanda has taken on the toughest gravel events — and the toughest questions — that face our sport. She has won Unbound Gravel twice and taken 2nd in the 350 XL. She has won Mid South and BWR San Diego and is the 5X-champ at Rock Cobbler in Bakersfield, CA. Amanda is co-host of the Groadio Podcast and she sits on the Gravel Cycling Hall of Fame Advisory Board. She is co-founder of the Mammoth Tuff Gravel Race, puts on gravel camps, competed in the first LIfe Time Grand Prix, and has a demanding day job. Somehow all of that is packed into one person. We guarantee you'll love this conversation with the fastest and fiercest Panda you will ever meet.

Josh and USAC CEO Brendan Quirk share a love of the history of cycling, as well as a deepseated desire to move it forward. In this wide-ranging conversation, Josh and Brendan talk about their love of bike racing, wind tunnels, and the complexities of cycling product development and retailing. Most importantly, they have a candid discussion of the difficult position USAC is in and Brendan's plan to move it forward.

With three Gravel World's Championships, an Unbound victory, an induction into the Gravel Hall of Fame, a bronze medal in UCI Worlds Road Championship TTT, a win in the Tour de San Luis, and more than a decade as a pro, Alison Tetrick has proved she's among the best in the world on pavement and dirt. As it turns out, she's also right at the top in analysis of the current women's pro peloton. In this episode, Ali (as her friends call her) details who to watch this year, talks about the overall health of women's racing, equity, parity, and — of course — marginal gains.

It's a no-topics-barred Ask-Josh-Anything episode of Marginal Gains, and (as usual) Hottie and Fatty get their own burning questions to the front of the line. Hottie desperately wants to talk about F1 porpoising and its connection to Hopf bifurcation. Josh accomodates. Fatty overheard a rocket scientist proclaim he wouldn't trust a repaired carbon fiber hardtail for technical mountain biking and now Fatty's scared about whether he's OK to ride. Josh reassures Fatty with the sage advice that "it depends." We then dig into actual listener questions about what kind of Ti alloy Silca uses when 3D printing, the pros and cons of 1X vs 2X drivetrain setups, and...how one might marginal gain a triple stroller in order to set a world record 10K pushing this pram. As always, this AJA episode's a great mix of thoughtful, serious, practical and silly. Don't miss it!
