Modesto's own Jon olsen ran 100.17 miles in 12:29:37 to become the second fastest American to run 100 miles on the track. He did so in the Desert Solstice Track Race, Dec. 15-16, in Phoenix.
That's 100 miles in less than 12 1/2 hours for a 7:29 pace.
The record for 100 miles on the track is 12:27:00.7, set by Bernd Hienrich in 1984.
"This is history in the making, a truly special moment in American ultrarunning," according to the Facebook page of Aravaipa Running, which hosted the race.
Olsen, a teacher at Prescott Middle School, is an international ultra-marathon runner, having been part of the U.S. team that took silver in the World Ultra Running Championships earlier this year in Italy.
He's already qualified for the 2013 U.S. National 24 Hour Team, which will participate in the 2013 International Association of Ultrarunners (IAU) 24-Hour World Championship in Steenburgen, Netherlands, May 11-12, 2013.
In addition, Olsen won the Modesto Marathon in 2010 and 2011 and nearly missed a three-pete this year.
