Somebody had to start this thread.
That is both running and riding. I was hoping to hit 3,600 miles of riding, but came in at 3,592.7. Close enough.
Also, what was your favorite bike-related thing? I'd say mine was either riding rental bikes out in UT/CO back in June or drop-barring my hardtail. That last one was a totally unexpected awesome idea. I don't have many of those. Or maybe it was my son discovering how much fun it is to ride his balance bike on singletrack. Actually, that's probably it.
