Flagstaff Downhill, Boulder, CO

Don't hit a deer at 50mph as you descent Flagstaff Road in Boulder, CO. This famous climb is a favorite of local and visiting pros. It took me about 40 minutes to take my time and climb it and about 10 minutes to descent it. Rumor has it that if you can climb this in less than 30 minutes after about a 4,000 Kcal ride (~4.5 hrs), then you might make it on the U.S. pro circuit. Sit back and descent with me as I try and not use my breaks on this epic road.

not sure...it's a tricky descent so you can't really take too many risks. People have been known to die on this descent from hitting cars or going off the side. A friend of mine actually smacked a deer once while roller-blading down it. I tend to be a bit conservative on most of it, but I'd say I've probably hit mid 40's on some sections.

How hard is the climb for a beginner? Is there any shot I'd make it the whole way up? I haven't ridden in a few years

Just moved to Boulder from flat and low Ohio. The ride down is terrifying! Too much sand and gravel in the turns from the continuous erosion.

Pushing it - I've hit 56mph between the top switchbacks and the very steep section after the fire station, and again between the amphitheater turn off and the upper bouldering area. No deer.

Old Stage Rd. is faster and straighter but has a stop sign at the bottom.

The "stare down" at the beginning is hilarious.  What's your record speed on this descent?

Thanks for the ride.
