I did the race two years ago on a geared bike, but have since spent more than a bit of time on a single speed and consequently think about how I would fair on the SS on various courses I have done. That being said, I think I'd rather take a SS to Leadville or Park City than to Durango. I remember eating up a lot of downhill miles at Durango on good quality gravel roads spinning in the big ring -- say at 20 mph or so. The up wouldn't be the problem (well, at least any more so than normal), but rather there is a lot of down that can be taken faster when 80 or 90 gear inches are available. In contrast, last year at Park City I spent very little time in big gears, as it was never very wide-open like a lot of the downhills are at Durango -- so a SS wouldn't have the same liability at PC. Similarly, spinning along the flats at Leadville at 15 or 16 MPH (comfortable for the gearing I would use on a SS there) wouldn't be much of a penalty, and the downhills are steep and curvy enough to not require much pedaling to obtain maximum speed.trail717 said:Overall the course has little "power spin in the middle ring" terrain, mostly climb followed by more climb then hard core climb and then some really fun descent then repeat - so maybe like you said, a good SS profile?
I hear ya about the rain. I DNF'ed (on a geared bike) the Brian Head 100 a couple of years back after about 60 miles. Thunderstorm turned the trail into muck. I ended up throwing my bike into a creek to get enough mud off of it so it could be pushed. If I do Durango, I am likely to do either the 100K or 50K. I like the idea of being done by the time the afternoon thunderstorms roll in (one speed or not).Ridemore24 said:It's a good race for a SS, as good as any other 100 miler. As mentioned, there are a few sections you'll be spun out, but I did not think it was to bad. Plus, it's likely rain, and while everyone else has drive terrain problems, you'll be cruising along just fine!
