The OGRE is a 150 mile course on gravel roads through the hills surrounding Lake of the Ozarks.   The Ozark region is known for hills, rocky soil, deep valleys, oak trees, springs, creeks and caves.   The course has been designed to "put you to work" right out of the shoot, then periodically allow for leg recovery on flatter stretches before hammering you again with the ups and downs of native Ozark topography.   There will be some pavement scattered throughout the race connecting gravel roads to gravel roads.

This IS NOT AN EASY course.  Training is required in order to complete such a task.  The OGRE is NOT for entry level cyclists.  Attempting to finish this grueling bike ride is ADMIRABLE.   Actually finishing the race will be REMARKABLE.


There will be 3 designated Pit Stops along the route where riders will meet their Support Crews.  Riders are required to check-in with Race Officials at the Pit Stop locations.  Pit Stops are the only locations where riders may meet their Support Crew to maintain or fix equipment and to re-supply.  Riders must remain on the same bicycle (frame) used at the start of the race.

At Pit Stop locations, riders will receive a map for the next leg of the course and an OGRE token for that Pit Stop.

Pit Stops will have cut-off times.  Any racer not making a cut-off time will be marked as DNF (Did Not Finish) and will need to be picked up by their Support Crew and removed from the course.  Cut-off times for Pit Stops will be based on an average 8.5 mile/hour speed.

Riders receiving any outside support along the course will be disqualified.  Riders receiving any support or assistance from their Support Crew at locations other than the Pit Stops will be disqualified.


There will also be Checkpoints along the route where Race Officials will be tracking the progress of the riders.  Riders will have the OPTION to stop at Checkpoint locations for rest or water.   These Checkpoints will be remote and manned by race volunteers. If you do not physically stop at a Checkpoint, please loudly call-out your race number to the volunteer as you pass by.   Note - your race number MUST be clearly visible at all times.

Pit Stops and Checkpoints will be clearly marked on Rider maps.


Each rider should carry water and nutrition for each leg of the race.   

There will be water available at specified checkpoints on the course.   Pit Stops (locations where riders may meet their Support Crew) will also give riders an opportunity to re-supply via their support crew.
