    From No Road Bike to Kona: A VC's Ironman Story with Alix Trebaol - #26

    Alix Trebaol signed up for her first half Ironman without knowing how to swim freestyle or owning a road bike. Six months of training later, she finished third in her age group on a hilly course in the Alps. After her first full Ironman in Barcelona, she got a coach and a TT bike, told her network she was going after a Kona slot, and qualified at her next race in France's Loire Valley. Off the course, Alix is an early-stage investor at Serena, focused on climate, energy, and healthcare. Before moving into venture, she was one of the first US employees at Too Good To Go, where the team grew from 10 to 150 people in six months. In this episode, she shares what she can tell about a founder in the first five minutes and why many top founders never pull up a slide. Takeaways Small details add up.

    Mapping Solo Ultras and Startup Roadmaps with Daniel Cerone - #25

    Daniel Cerone has run ultras across Hawaii, Italy, Sweden, and the Appalachian Trail, and he has never entered a race. He designs and maps every route himself, then runs it solo. It started with a childhood game of manhunt in the New Jersey woods and a trail he drew in Microsoft Paint, and it grew into a habit of asking what else is out there until the answer stretched across state parks and continents. In this episode Daniel walks through the 52 mile route he built along the Appalachian Trail from Harriman State Park to the Pennsylvania border. He talks about what went wrong on the day and what he learned about elevation profiles, calorie math, and carrying everything you need on your own back. He also shares the career built alongside it. After eighteen years in technology, including AI and cybersecurity work, Daniel rebuilt his company DCerone to help founders in AI and cloud compute run better beta programs. He explains the forever beta problem, the four pillars he uses to keep a young business from tipping over, and where he thinks AI falls short. Takeaways You do not need a race bib to go long distanceKnowing when to ask for help is as important as knowing the answerA beta with 3,000 free users and no conversion plan is not traction Chapters 01:33 Designing His Own Ultras09:27 The 52 Mile Attempt19:42 From Tech Career to DCerone24:10 Beta to Paying Customers34:32 What AI Cannot Do Links Website: dcerone.comLinkedInInstagram: dcerstudio

    Why He Signs Up for Races He Probably Won't Finish with Josh Rosenthal - #24

    Josh Rosenthal has toed the line at eleven hundred-mile races and finished two. He considers that a feature, not a problem. A Salt Lake City half marathon in 2010 turned into a five-year plan to reach a hundred miles, and a borrowed DVD of Unbreakable turned that plan into an obsession he's now fifteen years into, including five starts at the Zion 100. The same instinct runs through his business career. He released his first punk album at sixteen, and his dad's question afterward, "how do people know about it?", became the thread connecting everything since: ten albums, a coffee roasting company, thirteen restaurants, a private equity fund, and a cookbook co-authored with his wife. Today he runs Borderlands, a trail running media company built around the idea that the sport is worth more than its performance metrics. Takeaways If you're likely to finish, you picked the wrong distance. The low odds are the appeal.Longevity comes from being willing to quit. At 43, he thinks his PRs are still ahead of him.A great product is worthless if nobody knows about it. Distribution is the whole game.
