Real Fuel with SLS

In this episode of Real Fuel with SLS, host Stevie Lyn Smith catches up with professional ultra-runner Ryan Montgomery. Coming off a 3rd-place finish at the iconic Western States 100 in under 14 hours, Ryan breaks down his multi-year evolution from middle school cross-country in rural Alaska to competing on the world stage.

Ryan and Stevie dive deep into the real-world mechanics of ultra-endurance performance—covering mental growth, managing imposter syndrome alongside elite field competitors, and balancing an Ivy League MBA program with professional training. Most importantly, Ryan shares the exact fueling shifts, sweat-test revelations, and gut-training strategies that helped him eliminate GI distress on race day.

Key Takeaways & Highlights

• The Origin Story: How running in remote, rural Alaska set the foundation for Ryan's lifelong endurance journey.
• The 3 Performance Buckets: How Ryan categorizes his evolution into mental belief, training execution, and dialed-in fueling.
• Overcoming GI Distress: Why high sodium supplementation isn't always the solution—and how over-consuming electrolytes can actually trigger stomach issues.
• Liquid Fueling in Ultras: The mechanics behind transitioning to high-carbohydrate liquid nutrition and training the gut for 90–100+ grams of carbs per hour.
• Neuromuscular vs. Electrolyte Cramping: Why muscle cramps are often a sign of fatigue or insufficient carbohydrate availability rather than just electrolyte deficits.
• Career Dual-Tracking: Balancing a professional corporate/MBA track at Dartmouth Tuck while operating as an elite endurance athlete.

Have you ever wondered what it takes to turn your love for endurance sports into a sustainable, full-time coaching business?

In this episode of Real Fuel with SLS, host Stevie Lyn Smith is joined by 20-year industry veteran and endurance coach Michelle Lake. Michelle has coached athletes to world-class achievements—including coaching the oldest female Ironman Kona finisher in history—and now helps coaches transition from hobbyists to thriving "coachpreneurs."

Stevie and Michelle walk down memory lane, reminiscing about the "good old days" of mass starts, non-wetsuit-legal swims at Lake Placid, and tracking race progress by hand on paper. They dive into how communication technology like TrainingPeaks and Zoom revolutionized the coaching landscape, the common pitfalls modern coaches face, and why being a fast athlete doesn’t automatically make you a great coach.

Whether you're an athlete curious about coaching or an established coach looking to streamline your systems and set better boundaries, this episode is packed with practical wisdom and business strategy.

On this episode of Real Fuel with SLS I am joined by professional triathlete and endurance coach Lisa Becharas. We dive deep into the hilarious realities of racing, share unforgettable Ironman race-day blunders, and break down how the sport of triathlon has evolved over the years.

From navigating race announcer mispronunciations (and accidental identity swaps at the finish line!) to debating the true value of carbon-plated shoes and expensive bike gear, Lisa brings a grounded, refreshing perspective to endurance sports.

 Whether you’re a seasoned age-grouper, a novice triathlete, or a seasoned pro, this conversation is packed with relatable insights, race-day banter, and practical wisdom on balancing training, injury recovery, and race expectations.

Key Takeaways & Highlights

• Race-Day Mishaps & Announcer Blunders: Hilarious finish line stories, including announcer name mishaps, AI jingles, and the iconic energy of Ironman Lake Placid.
• The Evolution of Triathlon: How the sport has shifted from grassroots, budget-friendly racing (aluminum frames and basic setups) to high-tech gear, carbon-plated shoes, and rising race entry fees.
• Smart Fueling & Gear Debates: Lisa shares her early triathlon days (and infamous "sports bean" fueling strategy) versus modern nutrition and equipment trends like aero bottles and carbon shoes.
• Training Philosophy & Expectations: Why peak training volume doesn't always need to be extreme to yield high-performing results—and how to avoid over-investing in gear over fitness.
• Overcoming Setbacks & Injury Recovery: The mental shift required when coming back from injury and finding gratitude in the process.

In this episode, host Stevie is rejoined by fan-favorite and friend of the pod, Coach Nick Klastava. Nick is a dad, husband, running coach, and the brains behind the popular platform Running Explained.

If you have ever felt trapped by the numbers on your GPS watch, discouraged because you aren't hitting your college PRs, or lonely in a season of transition, this episode is for you. Stevie and Nick dive deep into "Act Three" of Nick's personal running journey, exploring how he moved from a burnt-out Division 1 athlete to finding genuine, long-term joy in endurance sports.

They tackle the toxic comparison traps that many seasoned and adult-onset athletes fall into, why hyper-fixating on your pace splits might be ruining your progress, and how shifting to RPE (Rate of Perceived Exertion) can completely transform your relationship with training.

Key Takeaways:

• The Three Acts of a Running Journey: Nick breaks down his transition from a high-pressure youth and D1 collegiate athlete (Act 1) to a social runner chasing performance in his 30s (Act 2), to his current era of experimenting with mileage for himself at age 44 (Act 3).
• The Danger of the Comparison Trap: It is incredibly easy to compare your current self to past versions of you. Nick shares how he had to humble his ego and acknowledge that an 18-year-old’s lifestyle demands something entirely different than a 44-year-old father of two.
• Workouts are for Gaining Fitness, Not Proving It: Why running your goal marathon pace on every single long run during a summer heatwave is a recipe for burnout. Training blocks are cumulative, and you are supposed to feel fatigued.
• Decoupling Joy from the Numbers: If you only stay in endurance sports to see faster numbers and constant PRs, you will eventually face a joyless experience.
• The Power of Time-Based Workouts & RPE: How Nick unlocked massive fitness by simply leaving the lap-split button alone and running entirely by feel and effort.

On this episode of Real Fuel with SLS, I am joined by professional runner, American record holder, and mother of two, Keira D'Amato. Fresh off the release of her new book, Don't Call It a Comeback, Keira opens up about her recent major surgery and her intentional, conservative approach to rehabilitation.

Keira pulls back the curtain on what it’s like to realize you’ve been living and training in constant pain, how her body learned to compensate over a five-year period, and why she is viewing this three-month reset as a beautiful opportunity to correct imbalances. From the hilariously relatable logistics of waist-deep pool running in running shoes to coaching her daughter's Girls on the Run team, Keira shares how she is finding joy in the current phase of her journey while keeping her eyes locked squarely on the 2028 Olympic Trials.

We also chat more about:
