    Episode 502: Backyard Ultra Records & Recovery | Phil Gore

    Phil Gore holds the World Best mark for the Backyard format, completing 119 "yards" for a total of 495.83miles. He recently completed a personal project, called Project 168, where he aimed to see if he would be able to last 168 yards (700 miles). He ended up tapping out at 152 yards (633.75 miles). We discussed this project, what the limiters were, how they have created a longer recovery, and what direction the Backyard Ultra World is going, and how his event raised nearly $300,000 for Telethon, a Western Australian appeal that supports sick, vulnerable, and disadvantaged kids and their families.

    Episode 501: First Double Amputee To Finish Leadville 100 Mile Run | Brian Reynolds

    Brian Reynolds is a Brooks-sponsored double below-knee amputee runner who, in 2026, became the first athlete in that category to finish the Leadville Trail 100 — on his fourth try, in 28 hours 55 minutes. He lost both legs at age four to meningococcemia, a rare bacterial infection with grim survival odds. For years he hid the amputation and stayed off the trails. A Grand Canyon hike cracked that open. He went from powerlifting to a 2:58 marathon, multiple classification records from 5K to the marathon, and Team USA para-athletics.

    Run The News | Phil Gore Shocks Backyard World & Meg Eckert Targets Men's 6-Day American Record

    Phil Gore holds the World Best Backyard record with 119 yards (495.87 miles). In an effort to see what he could actually do, he set up a project targeting yards/hours. Meg Eckert may be the most underrated ultramarathon athlete in the game right now. She is currently on pace to break her own women's 6-day World Record, and also the outright American Record. Finally, I touch on some thoughts around the UTMB events.

    Episode 498: 2:59 to 2:18 Marathon | Matt Fox - Sweat Elite

    Matt Fox joined me to chat about his interest in the marathon after coming from a National class middle distance background, his trajectory with content creation, the Chinese running shoe market, and his power weight ratio journey.

    Matt Fox: sweatelite.co | IG: @mattinglisfox

    Episode summary: Zach Bitter interviews Matt Fox (Sweat Elite)

    Matt's background: Former Australian middle-distance runner who twice finished 5th at Olympic/World trials (consistent 1:48 800m). Felt he "failed" after never making a national team, which later fueled his curiosity about how better runners train.

    How Sweat Elite started: After a failed Strava-like app, Matt launched a site interviewing pros. He later began filming elite workouts (inspired by old FloTrack videos), but it lost money due to last-minute travel costs and limited YouTube revenue. He recouped losses by documenting his own marathon builds.

    Content landscape: Athletes now prefer posting their own journeys, making third-party workout videos harder. Influencers-as-coaches is a growing issue; both agree formal qualifications aren't required (many great coaches never had them), but buyers should do due diligence. Bad influencer coaches can still introduce people to the sport who later seek better help.

    Creators they follow: Truett Haynes (humor + ambitious Olympic Trials goal despite current times being far off; recently hired Rory Linkletter). Also Eric Floberg (cinematography) and Rory Linkletter (authenticity, Canadian marathon record pursuit).

    Weight/body composition debate: Matt accidentally got very lean (70 kg) for a 2:20 marathon, then gained 3–4 kg and plateaued at 2:23–2:24. After noticing he was much larger than the Japanese runners he raced with, he used carb-cycling (high carbs around key sessions, deficit on easy days) to drop back to ~69 kg and ran 2:18–2:19. He has since lost another ~12 kg.

    • He stresses this is highly individual and risky. Personality matters: people with OCD/obsessive tendencies are more likely to develop RED-S or eating disorders. He now studies nutrition to give safer guidance.

    • Examples cited: Josh Kerr's long-term leaning-out, George Cush dropping weight before winning Comrades, Ryan Hall hitting a point where further loss hurt performance.

    • Both emphasize timing (fuel hard sessions, restrict on recovery days), not living in a perpetual deficit, and resetting after races.

    Chinese super shoes: Matt recently lab-tested 12 models from Anta, Li-Ning, 361°, Xtep, Dynafish, etc. Many perform comparably to Western shoes at half the price and often last longer. Notable mentions: Li-Ning Dragon Flight (79 g, technically illegal but extremely fast; a legal version is coming), Anta C10 (very similar to Puma Fast-R), Dynafish trainer (versatile, durable, sub-200 g).

    • Barriers in the U.S.: high tariffs, limited specialty-store distribution, and brands currently focused on the Chinese market. Anta and Li-Ning are expanding globally.

    Matt's current status: Recovering from injury, posting daily on Instagram/Strava as Matt Fox. Targeting a 2:17 or faster at the Melbourne Marathon in two months.

    Episode 496: Fueling Your Ultra: Strategies & Challenges | Vic Johnson

    Vic Johnson shares the practical limits of high-carb strategies, discusses how carbohydrate needs can exceed what the gut can absorb, especially under heat and high intensity. Vic shares typical successful ranges, why hotter races and faster pacing worsen digestion, and emphasizes consistent intake over large boluses that can trigger GI issues. They discuss individualizing targets for mid-pack runners, finding a personal carb "cap" in training then scaling back for race day, sex differences (body size, culture, psychology), links between GI issues and disordered eating, the role of day-to-day carb intake in building intestinal transporters, and practical choices between drink mix vs gels.
