Results: Live results can be found HERE which is available on https://brrm.com/results/cross-country-results/

Awards: This year we are not doing medals for the top 15, rather medals for ALL of the meet finishers. No team awards. Medals will be handed out at the finish line upon leaving the finish corral. And as a special surprise, we have medal toppers for those that run a PR. 

In order to receive your PR medal toppers, you will need to come back to the finish line once you have the total number of PRs run for the day. To be clear we’re only awarding medal toppers for lifetime PRs, not season PRs.

Concessions: None

Water Access: There is no water access at Buder Park. Please be prepared to handle your team's water needs (team jugs/bottles). We will have water and cups at the finish line for the runners as they finish, but after they leave the finish chute, please plan on being self-sufficient.

Tents: Will be allowed. Please be sure you are at least 20 ft. from the course.

Restrooms: Portapotties will be available on site.

Medical: We will have an Athletic Trainer on site courtesy of Mercy Sports Medicine.

Parking and Traffic: 

Traffic will be two-way race morning
Buses can load/unload near the start line, but will need to park in the rear lot. Please make sure they park in the back lot.

With the ground being so hard, we are able to park on the soccer fields behind the starting line. We will have parking volunteers helping folks find spots.

With additional parking available on the soccer fields near the start/finish area we are allowing buses to stay within the park. 
Exiting Buder Park onto the I-44 exit ramp is a challenge, please be patient it will take a while to get out.
