Dathan Ritzenhein exceeded the U.S. record for 10 miles on Monday in a workout.
The U.S. record holder in the 5,000 meters is gearing up for the World Half-Marathon Championships in Birmingham, England on Oct. 11.
Ritzenhein covered the 10 miles in 45 minutes, 3 seconds -- running 4:30.3 per mile. He did half the workout on the track and half of it on the road. Alberto Salazar administered the workout. -oregonlive
MY COMMENT: Oregon is so running crazy now workouts are making headlines! That being said, I guess a 45 minute 10 mile run is deserving. Ritz has to be physically and mentally prepared to run with anybody at the World Half. Watch it live at universalsports.com.
