i had one of those "bad days" today, i felt like garbage after riding 7 or 8 miles, and decided after 16 miles to just stop riding because i just didn't care about the ride anymore. honestly, today is the first time that i've ever felt that way, but it was a solo ride so it wasn't really that big of a deal. it actually started to make me wonder what causes something like that to happen though, because last week i felt much better doing the same exact ride, but i guess sometimes that just happens...
