We have about 100 days until the trip and have been working hard at improving my stamina for long distance hiking. In the past 3 months we have hiked about 120 miles, with about 32,600 feet of elevation up and down over 10 day hikes and two backpacking trips. When I first started, my average day hike speed was 1.4 mph, and now I average 2 mph. I have been keeping track of everything using my GPS.
I have lost 10 pounds and gained a lot of muscle. Hiking is more enjoyable and I feel more confident and less clumsy. But I still have a ways to go with overall speed, especially with a pack. I have to get up to 2.5 mph to match the leader's low speed.
