Had time for a quick ride this morning before jumping on a plane back home. This was a paved hillclimb right from our hotel in Boulder up the Flatiron Mountains. The gain is about 2400ft in 6.6 miles. Most of the vertical is gained in 4 miles at 11% average grade. The road is non-stop switchbacks and many fantastic views of Boulder are offered.
The coolest thing about this climb, and Boulder in general, is how many people ride here. On our 16 minute descent down Flagstaff, I must have seen 100 cyclists coming up. All types, mountain bikers, hard core roadies, young and old riders, single riders and groups of riders, you name it. We talked to a local rider who works in environmental issues at the top. He climbs Flagstaff every morning before work. Awesome. He commented that there's a 40-50 mile loop you can do with four out and back climbs that total 10,000ft of climbing. Think I'm moving to Boulder next.
