Wanted to ride ~55 miles yesterday, but only managed 40. Normally I would be discouraged by this kind of failure, but somehow I'm not. I really don't care at all. Maybe because before this year, a "long ride" for me was maybe 10 miles? Maybe because on this ride, I found a lovely new road to bike on?
I felt great for about 30 miles, but then I just felt sore all over. I tried to do the "just 5 more miles" thing, but it only worked twice. 
Anyway, hopefully I'll make my ~55 next week. Otherwise I might actually start getting discouraged.
