M60-69 at Rio Del Lago 100: Eric Johnson Leads a Six-Man Sweep to the Finish

• Eric Johnson won the M60-69 age group in 23:17:31 (13:59/mi), finishing nearly eight minutes clear of runner-up Mark Werkmeister.
• Mark Werkmeister, 64, ran 23:25:15 — the closest challenge to Johnson, with the two men separated by just 7:44 across 100 miles.
• Thomas Peterson crossed 4th in 24:58:19 despite starting the race well up the men's field, eventually settling at a steady 14:59/mi pace for the duration.
• All six M60-69 starters finished — a collective achievement across nearly 27-plus hours of racing in the California heat.

Eric Johnson made the M60-69 age group his from early on. Starting the race at gender place 77, he steadily climbed through the men's field across every checkpoint — 76, then 62, then 45 — before settling at 34th among men by the final stages. That kind of sustained forward movement over 100 miles doesn't happen by accident; Johnson averaged 13:59 per mile across the full distance and posted the 16th-fastest split in the men's field on the Overlook 1 to No Hands 1 segment, a stretch where the race often separates the patient from the reckless.

Werkmeister was the only man who kept Johnson honest. The Santa Fe runner made an even more dramatic early surge — vaulting from 89th to 52nd among men by the second checkpoint — before finding his cruising altitude and holding firm through the back half. His 28th-fastest men's split on the No Hands 1 to ALT segment showed he still had legs late. The 7:44 gap at the line is narrow for a 100-miler, but Johnson never relinquished the lead once he had it.

Behind the top two, the race spread out considerably. Peterson finished 4th overall in the age group despite logging the 28th-fastest men's split on the No Hands 2 to Overlook 2 leg — a sign of genuine strength late in the race that wasn't quite enough to overhaul Brian Siddons (3rd, 25:50:38), who had gone out conservatively and paid for it with a steady slide down the men's standings across the day. Chuck Amital and Julian Martinez rounded out the six, finishing within 25 minutes of each other in the final slots. Every man who started, finished — and at Rio Del Lago, that counts for plenty.
