The Trailbreaker runs through Waukesha each spring, with distance options stretching from a short road run up to a full marathon. The course moves through city streets and park corridors, and the whole event exists as a fundraiser for local parks, trails, and the urban forest. Volunteers staff the whole operation, which gives the morning a noticeably unpretentious feel.

The Trailbreaker has been held every year since at least 2019. That is as far back as RunSignup's records for this race go, so it may well be older.

Almost certainly not. Half the 13.1 Miles field finished slower than 2:10:22, and the last recorded finisher came in around 3:50:52, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.
It is a small race (111 finishers), which is friendlier and less intimidating than a big-city event, though the field thins out. There is no qualifying time, and the finish-time spread above shows how varied the field really is. If it is your first 13.1 Miles, that spread matters more than the winner's time.
The 13.1 Miles winner ran 1:26:53 while the median finisher took 2:10:22. That spread points to a mixed field, with a competitive front and a big recreational middle.
