About the Dog Days of Summer

The course circles Lake McIntosh entirely, splitting time between pavement and dirt trail. Mountain views open up on one side, farmland on the other, and there is wildlife along the water. Dogs are welcome to run with their people, which shapes the whole mood of the morning.

The start is at Dawson Neighborhood Park, near a pirate ship playground. Vendors, music, and games fill the area before and after the race. Part of the entry fee can go directly to the Longmont Humane Society, through an opt-in at registration.

Common Questions About the Dog Days of Summer

Will I finish last at the Dog Days of Summer?

Almost certainly not. Half the 3.5 Miles field finished slower than 43:55, and the last recorded finisher came in around 1:29:11, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the Dog Days of Summer a good first 3.5 Miles?

It is a small race (78 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 3.5 Miles, that spread matters more than the winner's time.

How competitive is the Dog Days of Summer?

The 3.5 Miles winner ran 22:27 while the median finisher took 43:55. That spread points to a broad, mostly recreational field rather than a race dominated by club runners.
