The Trailbreaker offers races at the Full, Half, 10k, and 5k distances. I opted in for the 5k distance.

Packet pickup is available the day before the race, as well as the morning of. And it's pretty straightforward, you grab your bib and away your go. Runners who registered before 3/18 got a race shirt, and runners who registered after that date got a race branded thermal; which I thought was a better option anyway.

None of the races start at the same time, which I thought was kind of unusual. While the start times are staggered, it does make parking a little more of an adventure for the later races if you don't arrive too early to Frame Park. We were able to find a spot arriving about an hour before the start of the 5k.

The Full, Half, and 10k all start and finish at more or less the same place, but the 5k starts a little ways down the parking lot, before finishing with the other races. All races are a shotgun start with a ship timed finish. This isn't an issue for timing since it's a smaller race, but it could be something to be aware of.

The 5k course is two loops around Frame Park in Waukesha, which is simple enough. Still, it helps to know the course ahead of time. The park has both pedestrian and bike paths, which go to different areas, and the section around .5 and Mile 2 had no course marshals. Other than one or two pink arrows spray painted, there was no course direction. Like I said, not bad on a double loop, but it would be prudent to at least put a person or a sign on some of those turns.

Going into loop two, be sure to not cross the finish line. There is sidewalk going into the finish and one going around, take the one around. Coming into the finish, also be aware that you're done. With all bibs the same, the volunteers didn't know who was running what race and tried to direct me, and others, the wrong way. This could be easily solved with the different races having different colored bibs.

The post race area was inside, which was clutch on such a cold day. Lots of food, beer, and vendors were available for all runners and awards were done as top finishers in all four distances were completed. Overall and Age Group winners received a certificate for their accomplishment.

All in all, the Trailbreaker is a very well run race and event. It's a smaller event, which you could expect for a spring race in SE Wisconsin.
