I got to ride Boulder to Estes Boomerang 200k Permanent on possibly the most beautiful day in Colorado this November. The route starts in Boulder and heads up Thompson Canyon through Drake to Estes Park, with final miles on beautiful Valmont Rd. It was great to see lots of cyclists out enjoying the nice weather!
Route on RideWithGPS (About 6000ft of climbing on my GPS, not 7600!)
