I used to ride lots of centuries on multi-geared bikes. I'm not quite ready for that on my fixed gear, but I did ride 51 miles today.
According to GPS, minimum elevation was around 40 feet above sea level, max was 480. GPS doesn't tell me, but I estimate steepest grade up was between 6% to 8%. Obviously my speeds varied a lot with hills, but on the flats I held steady around 17MPH.
I'm pretty sure I'll manage a century before the end of this summer or fall.
Instead of my usual urban riding, I'd like to try riding from Portland to Seaside Oregon. The most direct automobile route is Hwy 26 most of the way, which winds around a lot and has one summit around 1600 feet.
I'm still a flat-lander at heart -- so steep hills still worry me. But is this ride feasible on a FG?
