Written by two self-proclaimed "geezers" with more than 47 years of experience hiking together, The Geezers' Guide to Colorado Hikes is a book aimed at hikers over the age of 60 as well as notyet-acclimated visitors to Colorado who want a glorious out-door experience with minimal accompanying pain.

Fifty-six hikes are described that fit, in a graded fashion, the physical capabilities of most older hikers. While the majority of hikes listed are in the Denver/Boulder area and the nearby foothills, the authors have detailed several routes in Rocky Mountain National Park, Aspen, and Vail that will get more ambitious readers up into the high Colorado Rockies.

The authors also offer physiological and medical information to pro-vide an understanding of how the older body functions with effort at altitude. The Geezers' Guide includes

* An overview of the physiology of altitude and aging

* A summary of altitude-related medical problems

* Notes on hike preparation and what to pack

* 56 recommended hikes with • Degree of difficulty ratings • Maps • Distances • Driving directions • Estimated round-trip times • Starting altitude for the older hiker and elevation gain Trail description figures
