About the Thin Mint Sprint 2026

The course follows the Fox River through Lions Park, so there is moving water alongside much of the run. The route is flat and the surroundings are open parkland. Both a shorter walk/run and a longer option are offered, which means the field tends to be a mix of serious runners and people out for a morning stroll along the river.

Packet pickup happens at check-in on race morning, so there is no separate trip the day before. Parking is in the public lot on Lincoln Ave, near the local library, and from there you follow signs down Beachway Drive to the check-in area at the park.

Finish-Time Stats

Going by the 2025 results, this is a small, friendly field, and the spread of finish times is wide, so this is a mostly recreational race rather than one for club runners.

Common Questions About the Thin Mint Sprint 2026

Will I finish last at the Thin Mint Sprint 2026?

Almost certainly not. Half the 5K field finished slower than 41:49, and the last recorded finisher came in around 1:02:41, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the Thin Mint Sprint 2026 a good first 5K?

It is a small race (116 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 5K, that spread matters more than the winner's time.

How competitive is the Thin Mint Sprint 2026?

The 5K winner ran 19:26 while the median finisher took 41:49. That spread points to a broad, mostly recreational field rather than a race dominated by club runners.
