I did some cheating this weekend while we were in Colorado. Only got one ride in, but it was wonderful.
(Didn't really ride up the highway, but had to take the photo opportunity, lol)
I think I rode about 16 miles (my GPS stopped working reliably once I was in the park with the giant rocks). I was winded for sure. Awesome weather though. So many more trails I could have explored. I hope to get another chance to spend more time and have a few dedicated biking days.
