Where: Grayling Mich.  Registration at Penrod’s Canoe livery (go to www.penrodscanoe.com for directions)


About The Race: The Fall race (Aug 27) will be similar to the Spring Race. The course will be designed with the intermediate racer in mind and Check points will be pre marked on your maps but you will be required to navigate through all parts of the course. The race will contain most of the disciplines of a longer race in a long sprint format of 10-12 hours. Divisions for this race are male (MM), female (FF), and coed (MF). A support crew is not needed but spectators are welcome. Teams will be required to navigate during each stage of the race using provided pre-marked topographical maps, supplemental trail maps and specific course directions depending on the discipline. Teams must locate and check in at each of the required checkpoints during each discipline of the entire race.


Canoe: Teams will be paddling approximately 12-13 miles. The canoe sections will not include any whitewater canoeing, but an understanding of water safety is required. Canoes and paddles will be provided; everyone is required to provide their own life jacket. You may use your own personal paddles but they may have to be carried with you during the race.

Bike: The mountain biking portion will be 30-40 miles in length. The course will include a combination of single track, sandy two track trail roads and paved roads.


Orienteering/Trekking: Total orienteering will be a minimum of 9 miles – possibly more depending on the selected route. The terrain will include dense swamps, hardwood forests, and open meadows. Teams will also encounter water crossings and other natural obstacles along the way. Orienteering will be done from pre-marked maps, just know how to read and follow a compass and you’ll be all set.


Transition Area: This race will Start and Finish in different places and there will not necessarily be a central Transition area. Teams will be required to carry the necessary gear for all disciplines with the exception of a gear drop where you will be allowed to leave your gear bag (Race organizers will haul your gear to the drop, please bring large duffel or garbage bag to put gear into)


Cut-off Time: Teams must Finish the course within 12 hours to be considered a ranked team. There will be Mandatory cut-off times at certain points on the course, any team failing to make these cut-offs will be given directions to jump ahead on the course so that they may complete as much as possible of the event. All “short” course participants will still be officially ranked in the final order but they may not finish ahead of any team completing the whole course within the time limit


Weather: Race will be run regardless of weather

Prizes: Awards to a minimum of the top 3 in each division and top 10 overall. More prizes may be available depending on number of teams finishing.  Other cool draw prizes for all eligible racers and volunteers.
