Common Questions About the Spring - Mud Mountain Dam Marathon & Half Marathon

Will I finish last at the Spring - Mud Mountain Dam Marathon & Half Marathon?

Almost certainly not. Half the 13.1 Miles field finished slower than 2:10:40, and the last recorded finisher came in around 3:57:44, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the Spring - Mud Mountain Dam Marathon & Half Marathon a good first 13.1 Miles?

A field of 213 is big enough that you will have company at your pace without feeling lost in a crowd. 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 Spring - Mud Mountain Dam Marathon & Half Marathon?

The 13.1 Miles winner ran 1:14:56 while the median finisher took 2:10:40. That spread points to a mixed field, with a competitive front and a big recreational middle.
