To utilize the Blacktail Recreation Area the race will be staged entirely on the events grounds.

Transition areas will open for set-up at 6 a.m. and will close at 7:15 a.m. (Everyone must be setup by 7:15 a.m.)

The transition area will have an aid station with water and sports drink. Transition areas are for athletes only; family, friends, coaches, and trainers of participants are not allowed in these areas. Volunteers will be available for stripping of wetsuits and other assistance. Race staff does not transport gear from either transition area.


Wetsuits are recommended but not required for the triathlon; the water temperature ranges between from 60-65 degrees and warmer.


No one under the age of 8 years of age will be permitted to participate in either race unless specially approved by the race director.  All juniors, those participants under the age of 18 must attend the racers meeting.  Failure to attend the meeting will disqualify them from racing and they will not be allowed on the course.

 No music devices are not allowed on the bike!    They may be used on the run but volume must be low enough to allow participants to hear traffic, volunteers, police officers, and fellow participants.


The awards ceremony will start at 10:45 a.m.  Overall awards will be presented to the top three male and female finishers in the individual triathlon and duathlon races. Team overall awards will be given to the top three team regardless of age or gender.

Age group awards will be given to the top male and female finishers of the individual triathlon and duathlon races based on the number of entrance in each age group.
