Congratulations! I bet, if there's a 37 mile option at the next ride, you could do that by then. You have lots of time to train! I did a jump from 100 to 124, (the 100 being a Century in November, but then rides of 60-80 miles on Saturdays in between, till the 124 in January) which I thought would be pretty easy, but it was HARD (but maybe it was the wind) so I was really nervous about going from 124 to 192, (three weeks later) but at the lunch stop on the 192, which fell about 120 miles, I still had tons of energy left. And at the end, I was much less tired/sore than the 124! I am still amazed. That's how the body works- you stress it a little, give it a nice rest, and it's ready to go further, easier! I also like to think of it in terms of hours, rather than miles. It seems much less intimidating to me for some reason.
