I am new to Denver (Virginia Village) and am looking for a 7-8 mile stretch of road for FTP testing. Can any of you Denver area cyclists here make recommendations?
Waterton Canyon seems like a good option but may not be long enough. Any of the other canyon roads? Anything good east of 470?
Open to driving or riding to a course.
Welcome - there is nothing to the East but check out LookOUT MTN west of Golden or Deer Canyon West of Littleton / Highlands area.
Overall there’s incredible climbing west of you and nothing but flat to the north, south and east of you 
Welcome to CO Samuel. Hope you’re enjoying the riding out here. This segment will work for about 99% of the population:

If you go you can park right on the side of the road at Wadsworth and Deer Creek Canyon Rd. then ride into Chatfield to warm up.
Thanks, James. I’ll give it a try. I’ve ridden Deer Creek a few times but wasn’t sure if the grade was consistent enough. I rode east on Jewell from near Gun Club today. Too many rollers. Looks like some nice gravel though.
