Common Questions About the Heatwave Half Marathon/5K/10K - Ann Arbor

Will I finish last at the Heatwave Half Marathon/5K/10K - Ann Arbor?

Almost certainly not. Half the 13.1 Miles field finished slower than 2:12:41, and the last recorded finisher came in around 3:25:35, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the Heatwave Half Marathon/5K/10K - Ann Arbor a good first 13.1 Miles?

It is a small race (76 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 13.1 Miles, that spread matters more than the winner's time.

How competitive is the Heatwave Half Marathon/5K/10K - Ann Arbor?

The 13.1 Miles winner ran 1:18:18 while the median finisher took 2:12:41. That spread points to a mixed field, with a competitive front and a big recreational middle.
