This Halloween weekend race doubles as a fundraiser for a local elementary school. Costumes are part of the deal, so expect plenty of creative outfits at the start line. There are a couple of distance options, one a longer run and one a shorter fun run, so the field tends to be a mix of serious runners and kids doing their first race.

Almost certainly not. Half the 5K field finished slower than 34:34, and the last recorded finisher came in around 1:03:38, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.
A field of 425 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.
The 5K winner ran 17:57 while the median finisher took 34:34. That spread points to a broad, mostly recreational field rather than a race dominated by club runners.
