No, it wasn't me.
I know and have ridden with the guys who did, and I wanted to share their story.
Two friends from BikeJournal did a ride last week in their "neighborhood". One lives in Ft. Collins, CO, the other in Loveland, CO.
Starting at 5am, they rode the Grand Loop, from Loveland, Big Thompson Canyon, over Devil's Gulch into Estes Park, up Trail Ridge Road to 12,300' altitude, down the other side to Grand Lake and Granby, south to Frazier, Winter Park, and Berthoud Pass, then east to Idaho Springs, along I-70, and north to Golden, then north along the foothills back to Loveland.
15 hours 3 minutes ride time
17 hours 45 minutes total time (5 a.m. to 10:45 p.m.)
14,000 ft. of vertical elevation
12,300 ft. max. altitude
15.0 ave. speed
45 mph max. speed
I am entirely impressed, even though one of them is only 49.
These are the same guys who convinced me--a lifelong lowlander and flatlander, who smoked for 35 years and was only in his third year of cycling--that I could to go Colorado, climb Mt. Evans on one day, and ride a century from Loveland up to Peak-to-Peak and across to Estes Park and back down two days later.
If it wasn't for them, I couldn't have done it, nor would I have even tried.
Anyway, their story begins here, or you can skip right to the ride report, including photos, map and elevation profile (gasp!) here.
