Common Questions About the JeffCo League Championships

Will I finish last at the JeffCo League Championships?

Almost certainly not. Half the 5K field finished slower than 21:29, and the last recorded finisher came in around 29:22, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the JeffCo League Championships a good first 5K?

It is a small race (112 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 5K, that spread matters more than the winner's time.

How competitive is the JeffCo League Championships?

The 5K winner ran 17:51 while the median finisher took 21:29. That spread points to a relatively quick field, so expect a competitive front end.
