Well I managed to follow the correct Chubby Cheeks course directions today to get a decent GPS track of the marathon route.
Trails are in fantastic condition with only a few minor patches of ice and hard packed snow.
This map only includes the route from the Horsetooth Trailhead. The official route will start with about .65 miles downhill from Nick’s and then back up at the finish.
My GPS ended up at 23.4 for this run but the GPS tool I used to pull the profile came up with just over 24 miles. My GPS is usually a bit shorter than most maps or Garmins so it’s probably safe to say that the official route will end up at about 25 to 25.5ish depending on what mapping or GPS technology you believe in.
Total vertical for this route ended up at 6,100ft. With the final grunt up Nick’s hill, the official route should come out around 6,500ft as advertised.
