Historian - Thanks for the Longfellow! Definitely inspirational.
Training has commenced for the Kamala100 (that's what I'm calling the ride)! 1 hour total out and back on the Burke-Gilman Trail. Learned that false flats are lame and that however warm I get running or boot camping in 40 degrees and cold rain, it doesn't work for hands on a bike ride. Probably could have gone for a good bit more and at a faster clip if I hadn't had a weight training session in the AM and thrashed on cardio at the gym last night. On the upside, my butt was the only thing that wasn't going to be sore tomorrow and now I've got that covered. Feel real good though and the first one is out of the way.
Another positive is that I feel like my cardiovascular capacity was ok and that the thing holding me back was leg muscle stamina. Maybe that will change when there are some actual hills on the ride.
Thanks to everyone for the encouragement and suggestions!
