Missouri > Adventuremax Half Marathon & 10K Trail Run
Innsbrook, MO  •  Saturday, March 9, 2013  •  Course Map

Set for its 4th annual running as spring is just starting to shake off winter here among the forests, trails and backroads of the Innsbrook Resort in eastern Missouri -- but its first with the half marathon race distance -- the Adventuremax Half Marathon & 10K Trail Run is part of a two-day event organized by Ultramax Sports, which also includes an off-road team triathlon race on Sunday.

The half marathon and the 10K races will be run on Saturday, along an out-and-back course that starts and finishes near the resort's parks and outdoor recreation areas, just south of Lake Lucern and west of its golf course. From there -- the starting time for the race is scheduled for 10:00 AM for both race distances -- the course takes runners south from the resort into the woods and along the backroads that wind around the edges of the forest.

Much of the race unfolds through the forest trails, so runners should be prepared for plenty of challenging hills as well as muddy stretches, rocks, tree limbs and really everything you might expect to see along a backcountry trail. On Sunday, the off-road triathlon features canoeing, mountain biking and off-road running.
