The Trailbreaker
Race Day Weather
Cold start — layer up, moderate wind
Runners will start in chilly 36°F conditions — dress in layers for the corral and plan to shed early. Temperatures rising to 45°F through the course will gradually increase perceived effort in the second half. Moderate winds around 13mph may affect pacing on open sections of the course. Moderate humidity at 69% is worth noting for effort level, especially in later miles.

Race Info
The Trailbreaker is Waukesha's home grown running event and has been held annually since 1993. This Waukesha tradition initially consisted of a Marathon, Half-Marathon, and 5K Run/Walk. Both Marathon courses are certified by the USATF and may provide qualifying credentials for other races. We are excited to once again offer a 10K event at the Trailbreaker. The Trailbreaker originally was the brainchild of three running colleagues (amigos). Since 2009, the Park Foundation of Waukesha, Inc. (PFW Inc.), has organized and hosted this annual event as a fundraiser for the enhancement of city parks, trails, recreation programs and the urban forest.
