Narrowleaf Lake Run at Boyd Lake State Park 4, 7 & 10 Mile

Brisk autumn running in Colorado – OH YEA! Join us for a family fun event with FIVE distance options at the beautiful Boyd Lake State Park venue.

Choose your adventure! Heavy 5K, 10K, 15K (4, 7 or 10 mile) or 1 Mile Pumpkin race options. There is also a Kid’s Fun Run (1 & 1/2 mile options) as well!

This course is on perfectly paved walkways with about a half mile being off road on the south loop. Beautiful lake and wildlife views, NO vehicle traffic to worry about 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.

What’s a “Narrowleaf”?? The Narrowleaf Cottonwood Trees are the most densely populated tree species at Boyd Lake State park. We thought the name was fitting and unique to this venue.

This is the FIFTH ANNUAL running of this event!
