About the Janesville Shamrock 5K & 10K Run/Walk

This is a Shamrock-themed race that raises money for a local youth organization, so there is a genuine community cause behind it. Several distance options are offered, including a family walk, making it a race where people show up with kids and neighbors as much as with training plans.

Race-day check-in is held at O'Riley & Conway's Irish Pub, which sets the tone for the morning. A beer tent with live music follows the run, and packet pickup the evening before is at the youth club itself.

Common Questions About the Janesville Shamrock 5K & 10K Run/Walk

Will I finish last at the Janesville Shamrock 5K & 10K Run/Walk?

Almost certainly not. Half the 5K field finished slower than 36:18, and the last recorded finisher came in around 1:09:52, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the Janesville Shamrock 5K & 10K Run/Walk a good first 5K?

A field of 204 is big enough that you will have company at your pace without feeling lost in a crowd. 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 Janesville Shamrock 5K & 10K Run/Walk?

The 5K winner ran 20:24 while the median finisher took 36:18. That spread points to a mixed field, with a competitive front and a big recreational middle.
