The course runs along the paved roadways of the campground beside Diamond Lake. The race will use chip timing for start and finish. Water stations will be placed at approximately every 1.5 miles. Participants must finish at no slower than a 16 minute per mile pace. Packet pickup is held on race morning and typically begins one hour before the race.
Awards, swag and virtual entry
All finishers receive a custom finisher medal, a race-themed shirt, and a mimosa at the finish; juice and water are provided for participants under 21. Awards are given to the top finishers by overall and master age categories and to the top three in five-year age groups from 10 & under through 80+. The Virtual 5K allows participants to run off-site and submit results by the end of race day; virtual packages are shipped the Monday after the event to continental US addresses.
