Ok guys, can I get some advice/feedback on this hike or potential alternatives?
My wife and I will be in Colorado this summer from July 17-26. We going to be hitting up South and Central CO (Durango, Great Sand Dunes, etc). We will be starting Thursday in Ouray and stopping by the Black Canyon of the Gunnison that morning. We don't have a lot of interest in hiking there and may only stay around for the morning (or all day) depending on our plans for Friday – Sun.
We have a early flight out of Denver at 8:00 AM so we need to be in Denver for Sunday night.
We were looking at Maroon Bells. Never been, looks spectacular, and would like to get in some backpacking there. (I joined here because we are moving from dayhikes to backpacking and are starting out as light as possible.)
I was interested in 4 Pass Loop as referenced in the title. I am just not sure about covering the distance in 3 days and 2 nights. Plus we HAVE to get out in time Sunday to get back to Denver. Looks like most people are doing it in 4 days, but I saw one lady that was jogging it in 1 day!
Compounding the time issue is that it will apparently be very busy on the weekend.
For reference, we haven't hiked at this altitude before, but we will be sleeping at 7000 feet or greater for most of the week before we get there. Our most comprable hikes are dayhikes. We did about 17 mile roundtrip to Half Dome in <10 hours.
We will put in some training backpacking runs before we go in July.
