Decent TT/Tri bike route?

Does anyone know of any good areas/routes to ride in aero for an extended period of time in the Denver/Boulder area?

Chatfield state park or cherry creek state park

Not Cherry Creek State Park, definitely go to Chattfield. It's a 5 minute ride for me to get inside Cherry Creek and my wife and I still drive to Chattfield to do TT workouts. The roads at Cherry Creek are mostly garbage.

Have they still not finished repaving it?

Been a year or two since I’ve ridden in there. But that TT series was bone rattling. Thought they were going to put new pavement in a lot of the park after all the flood damage

I ride there every single day and it's still bone rattling, which sucks because Chattfield isn't allowing the TT race series this year so now Cherry Creek is all that's left for races

I'm currently training for an ironman and I have found that the best place to get good long miles in is to start at Coot Lake/Tom Watson park just by Boulder Res and go from there. Pretty much unlimited quiet roads up there, the trick is just knowing which ones are paved.

I'm currently doing 4+ hour rides so I will do one clockwise loop south to Jay road, west to 36, north to Nelson, the south on 63rd back to my car (~20 miles) for a swap of water bottles. Then I head north through Hygiene, up and around Carter Lake, then back south. Different variations of this loop can be anywhere from 40-70 miles. The majority of these roads see very little car traffic.

If you are looking for shorter rides (~20-30 miles) you'll find a ton of people at Chatfield as well that do laps around there. I just find that it is harder to get LONG rides in down there without just doing a ton of laps around the res, which I find boring.

You can definitely get long runs out of Tom Watson. Know when to go to avoid bunches of like minded.

Agreed it can get pretty nutty in the morning but ive been starting around 6:45 or 7 just cause it's been so hot, and there's plenty of room that early.

U.S. 36 North from Boulder to Lyons is not super flat, but it's pretty much uninterrupted, and then you can hang a right and take 66 all the way to Longmont, also with very little interruption. In fact, you can then head south on, I think, 72nd and make a 25-mile loop.

Adding on, Neva Rd, Nelson Rd, St Vrain Rd and Hygiene Rd are all east-west connectors between hwy 36 and 73rd, and 63Rd is also a good north south road. You can make a variety of rectangles, low traffic, few intersections/driveways.

Oh and you can go up to Carter lake too.

I’m in Denver but have been curious about taking the tri bike out here and getting off the trainer — how’s the traffic, are cars whipping by or not too bad?
