About the Bolingbrook Howl-O-Ween 5K

This is a Halloween-themed race that welcomes dogs on leash alongside their owners. Costumes are encouraged but not required, and neither is bringing a dog. Age group awards go to the top finishers across a full spread of categories, so there is real competition built into the morning alongside everyone running in ears and capes. The course is a standard road distance, nothing technical underfoot.

The race benefits rescue animals, which is the thread running through the whole event. Post-race, there are awards for the top male and female finishers overall. If you do bring a dog, the organizers ask that leashes stay short and that you clean up after your animal.

Common Questions About the Bolingbrook Howl-O-Ween 5K

Will I finish last at the Bolingbrook Howl-O-Ween 5K?

Almost certainly not. Half the 5K field finished slower than 39:59, and the last recorded finisher came in around 1:19:22, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the Bolingbrook Howl-O-Ween 5K a good first 5K?

A field of 233 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 Bolingbrook Howl-O-Ween 5K?

The 5K winner ran 20:03 while the median finisher took 39:59. That spread points to a broad, mostly recreational field rather than a race dominated by club runners.
