Broken Arrow Skyrace IFC — F20-29: Rentzke rules a high-altitude showdown

• Emma Rentzke won the F20-29 field in 2:26:52, averaging 29:22/mi across a course topping out above 7,100 feet.
• Anna Amato completed the field in 3:14:35 — a gap of 47 minutes 43 seconds separating the two finishers.
• Rentzke's pace was nearly 10 minutes per mile faster than Amato's 38:55/mi average, a margin that held throughout.

With just two finishers in the F20-29 field, there was no pack to hide in and no one to chase — just the mountain, the thin air above Palisades Tahoe, and a clock. Emma Rentzke, 26, from Fort Pierce, Florida, made the most of it. Her 2:26:52 finish at a 29:22/mi average is a genuine statement on a course that climbs through elevations where the air offers noticeably less oxygen — and that effort is all the more striking if she made the journey from near sea level in southern Florida without extended acclimatization time. We simply don't know her preparation, but the altitude context is worth noting.

Anna Amato, 21, from Town and Country, Missouri, crossed the line in 3:14:35 to claim 2nd in the F20-29 field. A 38:55/mi average on terrain like this is no small thing — the IFC course demands technical footing and sustained climbing, and finishing is its own achievement at any pace. The 47-minute, 43-second gap between the two reflects a race that Rentzke controlled from the front, not a close contest that slipped away late.

Warm and clear conditions — 70°F with barely a breath of wind — meant neither runner had weather to blame or thank. On a day like this, it comes down to legs and lungs. Rentzke had both.
