How far do you think you could run in 24 or 12 hours? Answer the question at the Bristow 24/12 Run, which tasks racers with completing as many one-mile loops they can in the allotted time. The course is pancake flat and has more variety in scenery than one might imagine in such a short distance.  Limited space available for 12-hour and 6-hour races. Proceeds from the Bristow 24 Hour Run support the Eugene to PCT Trail.
