 Ogden Marathon
The Ogden marathon has the potential to become a destination marathon simply because of the wonderful course. The gentle downhill lends itself to a fairly fast, relatively easy course. 950ft Drop from top to bottom. No hill climbs to speak of. Most of the course is flat and fast. The 6 miles from the top of the canyon through the bottom make up about 65% of the total elevation drop. |
