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. Source
