COURSE SURFACE
The course is primarily on East Plum Creek Trail and is 100% concrete.

DOGS, STROLLERS, ETC
Yes, your well-behaved, leashed dog is welcome here!  Yes, your well-behaved child in a stroller is welcome here.  Although, you may NOT ride on your stroller on the downhill portions.  It will be tempting, as those hills never disappoint those looking for a challenge. This course is suitable for all types of strollers.

SUPPORT*
5k:  There are two opportunities for water on the 5k course at miles .75 and 1.25.

10k:  The 10k will have four water stops at miles .75, 2, 4 and 5.25.

13.1:  The Half Marathon will see a water station 8 times  at approximately miles .75, 2, 4, 5.5, 6.5, 9, 11 and 12.25 with water and an electrolyte drink, at all of them. Energy gels will be at the southernmost water station at miles 5.5 and 6.5.

Port-a-Johns will be at the Expo (start/finish) and at approximately miles 5.5 and 6.4 on the half marathon course. 

CUPS - yes, there are cups at the aid stations but we are a cup-free finish line!

All distances are OUT and BACK, which means runners need to stay to the right to avoid oncoming racers.

*The 1/2 marathon course support and timing will be open for 3:30:00.  Racers must average at least 16 minutes per mile to remain on the course and receive course support.
