Thanks for a GREAT 2020 race everyone! We’ll update this info page soon with our 2021 race plans

Narrowleaf Lake Run at Boyd Lake State Park 4, 7 & 10 Mile
The autumn leaves are falling and brisk morning air gives you a rush of excitement. This is Colorado running in the fall! OH YEA! Join us for a family fun event with three distance options at the beautiful Boyd Lake State Park venue.

What’s a “Narrowleaf” you ask? 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.

Choose your distance! 4, 7 or 10 mile race options. 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.
