Spring is the season of renewal and beautiful Colorado running. We hope you join us for a fun adventure that embodies the spirit of springtime at the beautiful Boyd Lake State Park!

Choose from the Half Marathon (13.1 mile) or 10K (6.2 mile) for your run adventure. This course is on smooth paved walkways with about three quarters of a mile being off road. Beautiful lake and wildlife views and fun post race festivities. Did we mention almost no elevation gain? This is one flat course making sure you’ll set a new PR or enjoy a fun steady-paced morning run race.
