Broken Arrow 18K M10-19: Josiah Mcmahan Runs Away With It

• Mcmahan wins in 2:34:44 (13:50/mi avg), finishing more than 24 minutes clear of 2nd place — a commanding margin across 16.8K of high-elevation mountain terrain.
• David van de Meerendonk clocked 2:59:07 to claim 2nd, edging Isaac Kirby (3:12:11) by just over 13 minutes for the runner-up spot.
• Mcmahan's closing leg (High Camp→Finish) was the 27th-fastest split on that segment among all women — a blistering finish that underscores how strongly he came home.
• All three athletes navigated a course ranging from roughly 6,200 to nearly 8,900 feet, with a dry, breezy 65°F day that offered little mercy on the exposed upper sections.

Three teenagers lined up in the M10-19 group at Broken Arrow's 18K, and Josiah Mcmahan, 18, from Incline Village, NV — practically a local — made it look like a training run by comparison. His 2:34:44 finish at a 13:50/mi average over this relentlessly vertical course was the kind of performance that leaves little to discuss at the finish line. He entered the final stretch already pulling away, and his High Camp–to-Finish split ranked 27th-fastest on that segment among all women in the field — a sharp, aggressive close on terrain that breaks most athletes.

David van de Meerendonk, 17, making the trip from Bloomington, MN, ran a gutsy race to secure 2nd in 2:59:07. His movement through the men's field told the story: after a conservative start, he climbed steadily through the Siberia–High Camp stretch and ultimately crossed well inside three hours — no small feat at this altitude, especially for an athlete likely less acclimatized to Tahoe's thin air than his Nevada-based rival.

Isaac Kirby, 19, from Palo Alto, CA, rounded out the group in 3:12:11. Kirby faded somewhat through the middle of the race before steadying in the final stretch, finishing 13 minutes and 4 seconds behind van de Meerendonk. In a race this demanding — nearly 9,000 feet of elevation, exposed ridgelines, and 17 mph winds — simply finishing is a legitimate achievement, and all three did exactly that.
