Horse Illustrated Magazine

Picture this. You’re out riding on a beautiful trail in a state forest with a small group of family and friends. A group of riders pass you on the trail intently reading a map and a compass and whispering something about finding a paper plate.

A few minutes later you encounter another cluster of riders going the other way. They, too, have compass and map in hand and seem to be on a mission. You ask one of the riders what is going on and they call back that they are competing in a “CMO’’ as they trot by. CMO? What is that you wonder? Later in the day you happen upon base camp for the CMO and stop to chat. The ride manager fills you in and invites your group to join in tomorrow as guests in the Sunday CMO.

CMO is short for competitive mounted orienteering, which is essentially a road rally on horseback where you search a natural area to find hidden treasure (in this case, paper plates with codes written on them which are called “objective stations”) by using the trail map with printed instructions on the back and a compass. You navigate the old-fashioned way by taking compass readings off of landmarks; no GPS or cell phone navigation is permitted. The landmark descriptions are listed on the back of the map and help to determine the location of the objective stations by narrowing the search area where several compass coordinates intersect.

Once you locate an objective station, you record the station number and the two-letter code and ride date on the back of your map and then go looking for your next objective. The individual rider or team of two to six riders to locate all of the objective stations and then cross the finish line in the least amount of time wins. You can locate the stations in any order and ride as fast or slow as you wish. The plates are supposed to be visible from the saddle, so hopping on and off your horse is not usually necessary.

I first learned about CMOs from Kristi Crowe. Crowe lives in Valparaiso in Northwest Indiana, and went to her first CMO at the invitation of one of her fellow Porter County Sheriff’s Posse members.

“It was a lot of fun,” says Crowe. “I rode with an experienced team and learned the ins and outs while on the trail. The landmarks are up to the ride manager’s discretion and are generally a very creative description of a natural object. One of my most memorable landmarks was the ‘Octopus Tree’. That sounds like a very unique tree, but when you are out cantering on a trail, there tend to be a lot of trees matching that description!

“My horse when I first started CMOs was an Appaloosa/Thoroughbred mare named Dancer. She absolutely loved the sport. She relished in the race and especially the trip to the finish! Since then I have also competed my Trakehner mare Risa in CMOs.”

Anyone can participate on any kind of equid, and they can be ridden or driven (although if you plan on driving your horse check with the Ride Manager first.) The equipment you need is minimal: a simple orienteering compass and a marker that you wear on a lanyard; comfortable tack and riding clothes, and a good trail horse that is at least three years old. Competition entry fees are generally around $5 for juniors and $10 for adults with a $5 fee for riders who are not members of the National Association of Competitive Mounted Orienteering (NACMO).

Prizes are awarded after each ride and year-end and there are lifetime awards for cumulative points through the NACMO and the regional clubs.

“Competitive Mounted Orienteering was first envisioned as a sport in 1981 by Cliff Pladsen in Olgivie, Minnesota, as a game to play with his family while trail riding to improve their map and compass skills,” says NACMO President Marti Caldwell. “He developed rules and the NACMO came into being in 1983. There are now active chapters with a ride season of at least five rides per year in Minnesota/Wisconsin, Indiana/Illinois, Michigan, the Northeast (New York, Pennsylvania and New Jersey), Eastern Washington/Idaho, Alabama and a new chapter just starting up in Kentucky.”

Another great aspect of competitive mounted orienteering is that it is family-friendly.

“Our family moved to Minnesota in 1986,” says Caldwell. “My daughter and I attended a ‘fun’ ride put on by the CMO chapter for our 4-H Club there in 1987. We were immediately hooked. She was 12 at the time and we had just bought three horses. My husband started riding with us a year or so later and we stopped getting lost so often! We found the sport attracted people who became wonderful friends. These folks were true horse enthusiasts who could handle a fair amount of frustration and didn’t need an expensive prize to prove they had had a good time. We started the Indiana/Illinois chapter when we moved to Northwest Indiana in 1991, primarily as a way to meet more great people. Our kids are grown now, but still join us for CMO rides. Our daughter met her husband through our sport. Our son, who doesn’t ride much anymore, still comes to events to enjoy the great friends we have all made.”

CMO riders form a community and help each other often. “We have an award every year to recognize a person who has gone out of their way to help other riders with problems – flat tires, broken equipment, loose horses, forgotten ingredients for dinner – whatever,” says Caldwell.

Even though any breed may participate, Crowe pointed out some desirable characteristics in a good CMO horse.

“It must be a good trail horse,” she says. “It is helpful if your horse doesn’t mind being separated from others as you get your compass readings and search for the plates. If you are in it to try to win, a horse that likes to run is necessary.”

Since most CMOs are held over two days with a separate competition on Saturday and Sunday, many choose to camp overnight. The camaraderie of pitch-in dinners and sharing stories from the day’s ride around a camp fire are part of the fun.

Finally, bring your poker face and keep your lips sealed when competing in a CMO. You do not want to help opposing teams find the plates by making a lot of noise when you find one. Strategy is a big part of the sport. You need to plan a route to find the objectives and split up the tasks of taking compass readings, looking for landmarks, reading the map and marking down the codes.

“Competitive mounted orienteering may be the only sport where lying is encouraged,” laughs Caldwell, “You have to be careful not to tip off other teams when you find the objectives, so fibbing is part of the game.”

If you’re looking for a break from the show ring or to jazz up your trail riding, consider entering a CMO near you. The sport is becoming known across the country with new chapters just established in Kentucky and Alabama.

“We’re spreading it around,” says Kingdom Prairie Ride Co-Manager Svenja Chesna, “Every time someone moves they start a new chapter. That’s how this one started 20 years ago.”
