Andy Henshaw and Devon Crosby-Helms raced to victories in the USATF 100K national championships and shattered the course records in Madison on Saturday.
Henshaw, a 25-year-old Kansas University alum, maintained a swift pace of 6 minutes, 33 seconds per mile for the 10 laps around Lake Wingra, and took nearly nine minutes off the record set by Michael Wardian in 2008.
Henshaw crossed the line in 6 hours, 47 minutes, 34 seconds, roughly 12 minutes ahead of David Riddle, of Cincinnati, Ohio. Todd Braje, the winner of the 2010 Ice Age 50, took third with a time of 7:04:42. (Results are online here.)
The victory earned Henshaw a spot on the U.S. National team that will compete in the 100K world championships in the Netherlands in September.
Crosby-Helms, 28, secured a slot on that U.S. team for the fourth time, in a performance that knocked 14 minutes off the previous women's record on the MadCity 100 course.
The personal chef and ultra runner from San Francisco finished in 7 hours, 46 minutes, 33 seconds, about seven minutes ahead of Pam Smith, of Salem, Ore. Miho Tsumura, 37, of N.Y., was third in the women's division.
In the 50K race, Carolyn Smith, led the women and finished second overall. The Marquette University team physician posted a time of 3 hours, 51 minutes and 7 seconds. Jim O'Brien, of Chicago, won the 50K race in 3:27:07.
From her vantage point in the middle of the 50K pack, local runner Mary Gorski observed the remarkable speed and athleticism that Crosby-Helms and Henshaw displayed.
"It was still fantastic to have a front seat to some of the best distance running in the country," Gorski wrote.
"It's like having the opportunity to drive my Nissan in the same race as Jeff Gordon and Dale Earnhardt, Jr., in the Daytona 500 if I were a NASCAR fan. When Andrew Henshaw flew by me I thought, 'he must be on a relay, he is running so FAST!' What a treat to run alongside such talent -- even if only briefly. The same for Devon Crosby-Helms and those long legs stretching like a gazelle across the course."
