In this episode of Run Long After 60, I’m joined by ultrarunner and endurance phenomenon Pamela Chapman-Markle — known to many as @UltraPam100.
Pamela began racing at 55 and chose a 100-miler as her first event. Since then, she’s built one of the most extraordinary late-life endurance résumés in the sport: multiple finishes at Badwater 135, a perfect 10-for-10 record at Keys 100 (the only person in the world to do so), finishes at Brazil 135, and a continued pursuit of the longest, hottest, and hardest races on the calendar.
At the time we recorded this conversation, Pamela was 69 — and since then, she’s turned 70 and kept right on moving forward. The perspective she brings here reflects not a moment in time, but a way of living and training that continues to evolve.
Before all of this, Pamela spent more than four decades as a CRNA delivering anesthesia — a career that shaped her discipline, precision, and respect for recovery. In this conversation, we go deep into what it actually takes to run long at this level later in life.
We talk about coming back from a total hip replacement, including the role of AlterG training and progressive loading.
We dig into flatland training for mountain races, heat
adaptation, sodium and fueling strategies, strength work for masters athletes, hormone health, and the realities of crewing and pacing when races stretch through the night.
What stands out most isn’t just Pamela’s achievements — it’s her clarity, humor, and grounded confidence. She sets big goals not to chase records, but to stay engaged with what makes her feel alive.
This episode is a masterclass in smart longevity — a blueprint for running long, strong, and joyfully, no matter when you start.
Run Long After 60 is a show about people who continue doing hard things because movement, challenge, and curiosity still matter.
Note: These early episodes were originally recorded for video. Audio quality may vary slightly from episode to episode, but the conversations remain intact and unedited.
