About the Run4Kids Ultra Running Party

The course is a loop on a mix of dirt track, pavement, and smooth dirt trail. Each lap has a couple of short climbs, but the race director designed it so the descent is longer and gradual enough to carry you forward rather than beat up your legs. The surface changes keep it interesting, and the overall grade stays manageable throughout.

Runners can park their cars along a designated stretch of the course and set up their own personal aid stations there, which means your gear is never far away no matter how many laps you run.

Common Questions About the Run4Kids Ultra Running Party

Will I finish last at the Run4Kids Ultra Running Party?

Almost certainly not. Half the race field finished slower than 2:23:58, and the last recorded finisher came in around 2:56:56, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the Run4Kids Ultra Running Party a good first race?

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

How competitive is the Run4Kids Ultra Running Party?

The race winner ran 1:55:25 while the median finisher took 2:23:58. That spread points to a relatively quick field, so expect a competitive front end.
