Welcome back or welcome to the single track podcast. I'm your host, Finn Melanson, and in this

episode, I am talking with Andy Blow, the CEO of Precision, Fuel, and Hydration. A note up front,

precision is a major partner of the single track podcast. It is a partnership that we are very

proud of, but it should be disclosed up front. With that said, this is not a conversation

that's contractually obligated. That's said, this is not a conversation that's contractually

obligated. That's to say, this is a conversation that I've been looking forward to having with

or without the partnership. As you may have noticed from recent episodes with folks like Scott Frey and

Jeff Burns, I am increasingly interested in the human performance and technology sides of the sport. And I think Andy is a

perfect person to speak to the progress that has been made in our sport in recent years from a

sports nutrition standpoint. Some of Andy's credentials, he's got a sports and exercise science

degree from the University of Bath. He worked as a sports scientist for a few Formula One

teams, and he helped establish the Porsche Human Performance Center before going on to found

his current company, precision fuel and hydration. In this conversation, we cover some of the basics,

but also get into the weeds. Andy explains key hydration concepts like sweat rate, sweat sodium concentration,

and blood volume contraction, the dangers of chasing marginal gains before mastering the basics,

why real-time sweat tech isn't quite ready yet for the masses, ballpark accuracy versus

perfect precision in fueling and hydration, aid station decision making, guardrails, and crew strategy,

and the frontier of fueling and hydrating for multi-day races. I learned a lot in this one

and hope to have him again on the show to cover many more topics, especially around carbohydrate

intake. Also, honestly, just like the business of precision, I find it to be a really fascinating

topic. Anyways, hope you learn a lot from this one too. Yeah. This is a good. also honestly just like the business of precision i find it to be a really fascinating topic um anyways

hope you learned a lot from this one too yeah this episode of the show is brought to you by norda
