The Vallecito Lake Heavy Half Marathon is a beautiful and scenic course around Vallecito Lake. Nestled in the heart of the San Juan Mountains in Colorado, our race course takes runners completely around the picturesque Vallecito Reservoir with a special section that runs right across Vallecito Dam. If you ever wanted to run all the way around the lake, this race is the only way to do it as a portion traverses private property that is normally not open to the public.  The full race loop is approximately 13.8 miles. After the race is the best post-race meal you will ever have provided by the Rocky Mountain General Store and Meats (includes great veggie options also).  Grab a few friends and spend the weekend in the beautiful Vallecito Valley.  More than just a great race, this event is a fundraiser for local non profits.

New in 2024:  Single Track!  In 2024 a segment of the paved county road will be replaced with the dirt trail that runs between the road and the lake.  There is no measurable change in the race distance, but a significant increase in the scenery.  To mix things us the loop will also be run in the opposite direction this year.  Word has gotten out on how great this little race is and we expect it to sell out in 2024 as there is a 200 runner cap.  When it does sell out you can sign up for the waitlist.  Lastly, all Durango Running Club members get a 10% discount!  Make sure you are logged in to your Runsignup account and that your membership is current before registering and the discount will automatically apply.
