I did 162 miles this month (yeah, I know), for an average of 40 a week (there was a week in there that I didn't ride, but still). The very wet spring didn't help anything, but right now, if I ride more than two days in a row, my knees start complaining. The major mental barrier is regularly completing 30-mile rides, as this is the first season I've actually been riding distances consistently. Physically, it's not a problem, as I've done it before. On top of that, I'm trying not to do too much because last year I did way more miles in one week than I should have and burned myself out on riding until September.

Surgtech, good for you!
