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

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

Almost certainly not. Half the 3.1 Miles field finished slower than 39:26, and the last recorded finisher came in around 1:23:51, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the DoNot Stop Half Marathon/5K/10K - Ann Arbor a good first 3.1 Miles?

It is a small race (147 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 3.1 Miles, that spread matters more than the winner's time.

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

The 3.1 Miles winner ran 21:21 while the median finisher took 39:26. That spread points to a mixed field, with a competitive front and a big recreational middle.
