Hello all, my 1st post, I've been reading for a while and decided to finally get in on the action. My name on here represents the climbing/hiking limitations of living in Iowa. I am very much a novice but have started training to be more serious. We vacation in Breckenridge, CO ever other summer. 1991 tried Quandry Peak and got rained out somewhere around 12k. 1993 completed Quandry, 1995 summited Mt. Elbert. Will be giving Longs Peak a shot in early July, and right now have 2 overnight permits for Whitney on Sept 20. I am hoping to get some advice from people who are familiar with any of these 3 and Whitney. Whitney @ 22 miles is considerably longer round trip (main trail), at an avg of 10% grade. I think Quandry(7 miles) 19% & Elbert(9 miles) 20%. I would like to know how they compare and differ in real life. Am I making a fair assessment by comparing the distance and grade or are there other factors I should be considering. I plan to do Whitney as a 2 day and will do Longs Peak as a 2 day as practice, as I had never camped on a hike before. I haven't had an issues with the altitude to date, but wonder how the longer time up higher will affect me. Any advice or input is greatly appreciated.
