Tahoe Rim Trail 100K M<20: Robert Miller Owns the Under-20 Men's Field

• Robert Miller won the M<20 race in 13:42:52 (13:15/mi avg), posting the 9th-fastest split on the Waterfall→Finish segment among all women's field runners he was tracked against.
• Gabe Ramirez completed the 100K in 22:59:58 (22:13/mi avg), finishing 2nd in M<20 — 9 hours and 17 minutes behind Miller.
• Miller's pace of 13:15/mi across a course ranging up to 9,003 ft in elevation is a genuine achievement for a 19-year-old covering 100 kilometers at altitude.

With just two finishers in the under-20 men's field, the M<20 story at the 2026 Tahoe Rim Trail 100K belongs almost entirely to 19-year-old Robert Miller of Tahoma, CA. Running a course that climbs to over 9,000 feet — where thinner air can turn already-demanding effort into something else entirely — Miller crossed the line in 13:42:52, averaging 13:15 per mile across the full distance. That's a composed, measured effort for a teenager on one of the more demanding ultra courses in the Sierra Nevada.

Miller's race had real movement in it. He surged as high as 9th in the broader women's gender tracking early in the race before settling back through the field as the miles accumulated, ultimately closing with the 9th-fastest Waterfall→Finish split among that same group — a strong finish to a long day.

Gabe Ramirez of Walnut Creek, CA deserves credit simply for finishing. At 19 years old, completing a 100K ultra at high altitude in any time is no small thing, and Ramirez did exactly that, crossing in 22:59:58 (22:13/mi avg) to claim 2nd in M<20. The gap to Miller was wide — over nine hours — but the finish line is the finish line, and Ramirez earned his.

Two starters, two finishers: the under-20 men's field went two-for-two on the day, which on a 100K at altitude is its own kind of story.
