On this episode, Russell Ditsworth and co-host Corinne Shalvoy dive into the Desert Solstice Invitational, Aravaipa Running’s invite-only track ultra designed for records and national-team qualifiers. They break down why this meet exists, how athletes get in, and what makes a 400-meter loop the fastest laboratory in ultrarunning. You’ll hear how 24-hour and 100-mile efforts work on the track, the A/B standards for entry, and the staggering benchmarks set in recent years, including world-class 24-hour totals and the current 100-mile mark. Russell and Corinne unpack pacing, direction changes every four hours, lane etiquette, shoe rules, and why fueling can make or break an elite attempt. They also speculate on who could thrive at Desert Solstice this December, what trail stars might do on a track, and how high-carb strategies could push records lower. If you’re eyeing a timed event to practice night running, refine nutrition, or chase a standard, this episode gives you the playbook, and a few bold predictions.

Ultra Uncovered revisits Javelina 100 week with Corinne Shalvoy’s breakout 2024 run: 15:24 for fifth place, a 12-hour PR, and one of the fastest women’s times in race history. Corinne, Russell, and pacer-crew chief Graham unpack how she ran by effort through triple-digit heat, kept moving with simple mantras, and used cooling tactics like ice bandanas, sleeves, and even ice in the sports bra. They cover the build that worked—years of steady mileage, a late-block FKT, marathon-style long runs—and the mid-race problem solving that saved the day when cramps and hot spots hit. Expect actionable takeaways on pacing loop two, fueling through stomach swings, gear that helped (Agravic Speed Ultra, Omius visor, pockets that carry a full loop), and pro crew tips like booking a tent at jeadquarters. Bonus: a hilarious mid-race cameo with Erin Clark and a shirtless Adam Peterman, plus big gratitude for the Javelina community and livestream that kept the vibes high.
