walk EVERY morning 2-4 miles with 30# pack, 5 am, followed by 250 situps rain, snow, wind, thunderstorm, heat, earthquakes, I go good practice for what mother nature may throw at you in the mtns., also test your gear of course, I'm over 60 so I gotta get up and water the garden anyway by 5am
weights 2x/ week one interval session per week (hill repeats or eliptical machine-yuck) bike the hills once a week
running after the age of 50 is playing the losers game unless you can outrun an elk
