Just resurrecting this thread to let you all know I did it. Rode my age today (actually according to the Garmin, I rode 58+ miles, which is 5 miles past my age today). Did it just within the 2-week window that someone posted; would have done it sooner, but last weekend we were out of town, and on my birthday I was recovering from the day before's ride which for some reason gave me some issues. Didn't quite climb my age x 100 feet in elevation (as someone else posted), though I did get 4100+ feet of climbing in, which is a bit more than I'm used to on my fixed gear. Looking forward to doing it again next year, though maybe on my road bike.

Thanks again,
