Additional Information

Race Day Check-in and Shuttle

Due to limited parking at both the start/finish, runners will be shuttled both to the race start and from the race finish back to the Stearns Heritage Hall, the same location at packet pickup and race morning check-in. The shuttles will leave the Heritage Hall around 7:10 am race morning. Check-in will be at Heritage Hall from 6:00 to 7:00 am. We will begin loading the shuttles around 7:00 AM. Finish line shuttles will be provided to get runners from the race finish at Blue Heron to return runners to their vehicles at the Heritage Hall. All participants are asked to park at the designated parking areas at the Heritage Hall.

Runners will not be able to leave anything on the shuttle buses, but we do allow for you to take 1 drop bag which can be left at the finish for when you complete the race. Please be sure to label your drop bag with your name and bib number. Also see our list of rules for drop bags.


All 20K finishers will receive a finishers award. We will have unique handmade awards for the top finisher male and female in each age group. (18-29,30-39, 40-49, 50-59, 60+)
