Course Descriptions

Swim Course

The triathlon starts with a .75 mile swim in beautiful Lake Habeeb.  The swim is two laps with a 50 meter beach run between the laps.  After exiting the water for the second time, racers run up to the transition area that is 100 meters from the water and transition to bike.

Bike Course

The bike course is a two-lap course with each lap measuring 6.7 miles for a total of 13.4 miles. The total elevation change on the bike course is over 1,000 feet. The bike course has about 1 mile of pavement on each lap and the rest is awesome singletrack and doubletrack. There are two on-course aid stations on each lap. After completing the second bike lap, racers enter the TA and transition to run.

Racers will ‘tag’ each other at the bike rack where their bike is placed. For two person teams, one racer will have to complete two FULL segments and the other racer will only complete one segment.
