I need to flag a data issue before writing: the "moves" lines for all four athletes reference women's gender place (e.g. "gender place 224→217→201→191→198") and "women's split" — but these are M70-79 men. That appears to be a data labeling error in the payload. I'll treat those gender-place progressions as the athletes' men's field positions and the split rankings as men's field splits, which is the only sensible interpretation for this cohort. I'll write accordingly without inventing any detail not supported by the data.

Broken Arrow 18K M70-79: Dombrovski Leads Wire to Wire at 73

• George Dombrovski (Fairfax, CA, age 73) wins in 3:50:49 — nearly 31 minutes clear of the field — averaging 20:38/mi across 8,820 feet of high-altitude terrain.
• Dave McNaughton (Defiance, MO, age 74) holds off the rest to claim 2nd in 4:22:00, with the strongest finishing leg of the group.
• Tim Stanley (Herndon, VA, age 70) finishes 3rd in 4:36:29, posting his best relative split on the KT 22→Siberia segment.
• Robert Chacon (Dublin, CA, age 70) rounds out the four-man field in 5:06:35 — a 27:25/mi effort across a course that tops out near 8,820 feet.

Four men in their seventies took on one of the most demanding 18K courses in the country — a high-altitude grind through Palisades Tahoe that ranges from 6,200 to nearly 8,820 feet, where thin air and relentless vertical can test even the most seasoned mountain runners. On a clear, mild morning, George Dombrovski made it look as controlled as a race can be.

Dombrovski, 73, moved steadily through the men's field from the opening segment onward, climbing from 224th to as high as 191st before a slight settle on the final stretch — a sign of a well-managed effort rather than a fade. His 3:50:49 at 20:38/mi was the class of the M70-79 field by a commanding margin, and his strongest relative showing came on the Siberia→High Camp climb, where he posted a standout split among the broader men's field.

Behind him, Dave McNaughton (age 74, 4:22:00) earned his 2nd-place finish with a strong close — his best segment came on the High Camp→Finish descent, where he logged a competitive split in the men's field. The gap from 2nd to 3rd was a further 14 minutes: Tim Stanley, 70, crossed in 4:36:29, with his sharpest relative effort on the KT 22→Siberia stretch. Robert Chacon, also 70, completed the field in 5:06:35 — finishing a course that would humble runners half his age, at altitude, in a time that required sustained effort across every segment.
