When I am backpacking I tend to limit my daily miles to between 10 and 12, allowing for about 2500 feet of elevation gain and a total load in the neighborhood of 27 to 31 lbs. I rarely carry more than 34 lbs. My speed tends to average right around 2 mph when I am actually walking, give or take. I try to strike a pace that I can sustain uninterrupted for at least an hour without a stop, but of course I stop to take pictures or admire a view. The trails around here are never particularly level, so I can't say much about my speed on the level.

In contrast to Pika, I am 60 years old and I envy him a bit. I hope I am as fit at his age.
