T-1: Transition from Swim to Bike
  The sprint to the transition area after the swim is sand/rock/soil. If you have tender feet, flip-flops are recommended upon exit. An area will be designated for flip-flop gear-up. With foot protection, you must run a 500+/--yard sprint to the transition area. 

BIKE: 12.6 miles

The bike course is a combination of Forest Service Road and trail. Trail bikes are recommended, but possibly advanced cross bike users can ride this terrain. The Forest Service Roads are rutty and rocky. Please use extreme caution for yourself and other riders at all times and if passing. Head phones are not recommended. The route map will be made available to test-ride beforehand; online or through Como Trails Club.  The course is currently tagged in silver and pink plastic strips. MAP


RUN: 7.7 miles
  The run course will begin on the north side for safety reasons and the least amount of hiker traffic earlier in the morning. The run will be towards Rock Creek Falls around to the south side and finish on the long stretch of the dam. The trail has varied running surfaces of rocks and well-used single track. Pass with verbal notice and caution.  For this reason headphones are not recommended.  Use etiquette with hikers, horses, and wheel chairs!  Signs will be posted of event in process.

Race numbers must be worn on the front of the runners garment and visible at the finish line.
