Half Marathon map

Aid Stations/Mile Markers

There will be several aid stations along the course, as well as paramedics traveling the course. Water, Gatorade Endurance Formula, and portable restrooms are available at miles 2.25, 4.75, 7.25, 9.75 and 12 as well as the Start/Finish.  GU gels will be at the mile 7.25 fluid station. Food will be provided at the finish.

Weather Policy

Race officials may cancel, delay or change the event in case of extreme weather or other conditions that may affect the safety and health of the participants. In the event of cancellation, refunds will not be issued.

Corral Start

We use a corral start for the race.  There are designated start areas designed to facilitate an efficient start for all participants by grouping runners with similar anticipated race paces together.  Look for pace signs with your personal pace-per-mile. (For example, if you are planning to run 10 minutes per-mile, line up behind the 10 minutes per-mile sign.)

There are access points to each of the 6 corrals (7, 8, 9 10, 12 & 14 minutes-per-mile) along the sidewalk on the west side of Riverfront Drive. Be in the appropriate starting corral at least 15 minutes before the scheduled start of the race.  We use electronic timing chips attached to the back of your Race Bib. Don’t worry about the minutes it takes before you cross the starting line — they won’t count in your final time.


We utilize the ChronoTrack “B tag” system for race timing. The “B-tag” will be affixed to the back of the race bib. Do not peel off the “B-tag”.  No additional steps are needed prior to the start of your race.

Make sure the race bib is attached to the front of your body and is placed on the bottom layer of apparel that will be worn throughout the race. Do not fold or wrinkle your bib prior to attaching it, and make sure it is not covered by a race belt, water bottle, etc.

There will be race clocks at 5K, 10K and 15K.

Runner Tracking

With Runner Tracking, friends and family can track your location on Race Day as you MOOOve along the course! Each time you cross a timing mat, an alert will be sent with your pace and location. Share this link with anyone who wants to follow your progress!

Please note this link will not be active until the bib numbers are assigned. We do not recommend anyone sign up for runner tracking before Saturday afternoon (10/5).


We are asked all the time if walkers are welcome, and we happily say yes!  We just ask that everyone maintain a 16-minute mile pace. If you are unable to maintain that pace, that’s ok, we will ask you to move to the sidewalk and finish the race obeying the traffic laws as we will re-open the roads.

Time Limit Rules

The half marathon course route re-opens to traffic beginning 20 minutes after the official race start, each mile every 16 minutes. The finish line will officially close at 2 p.m. The time limit rules will be strictly enforced.
