Wow, thanks for the detailed route description...I just might try that. I'll also have to head over to REI and pick up that map. I decided to head east this morning, after all. I just drove over to Pecos Park this morning (Pecos and W. 96th Ave) and started from there. That trail is apparently called the Niver trail. Not too bad...almost all trail except for a little bit on Coronado Pkwy (starting around 84th Ave just east of I-25). You eventually connect with the South Platte River Greenway and head south. Turns out it's not a bad trail, except for a few detours in Commerce City where they're renovating the trail. The detours are well-signed, but, um, those streets in Commerce City by the factories are a little sketchy. Anyway, I took a few wrong turns and had to backtrack a few times this morning, but still a little under an hour. I'm sure it will be faster if I decide to go this way again! Thanks everyone for your replies!
