The Timberman is a 100% volunteer run organization. The volunteer base consists of the race directors (Amy and Alan Dettmer), the race committee (30+ dedicated people), and the over 125 local citizens who help the race run smoothly. The race committee has many years of experience to help ensure a safe race.

The race starts and ends on the grounds of Sugar Lake Lodge.
The swim is in the crystal clear, clean, turquoise waters of Sugar Lake. No swimmer’s itch from Sugar Lake! The bike is of rustic beauty using rural, county roads, most of which are newly paved. The relatively flat run course takes you through the resort and out and back on pavement with some gravel (International course) to the finish line. 

The Timberman Triathlon is sanctioned by USA Triathlon (USAT) and requires each participant to purchase his or her own one-day license or hold an annual membership in order to participate in the race. During registration, you will be directed to the USAT modal to enter your annual membership number or purchase a one-day or annual membership.
