Went on a 52-mile road ride with three others:

My legs weren't all there, since this came only 10 hours after my 80-mile 8000ft-ascent ride yesterday night. But I got some good training out of this one, we all threw down some solid efforts out there. I finished with an attempt to improve my KOM record on Riverside, which is a short climb. My tired legs ran out of steam about 2/3 of the way up (one minute in), but I limped on through and still took home a new KOM record, down 9 seconds to 1:36. With fresh legs, I will definitely be able to bring it down further.
So that's 52 miles, plus 3 miles to get to the starting point, for 55 total.
Total: 3903
