You don't need to power hike, just hike and enjoy it. Power hiking, especially on hills can lead to problems with the knees and Achilles' Tendon.

If you hike at a comfortable pace all the time, and stop before you get tired, gradually your distance and pace will increase without any big effort. It takes a little longer to do it this way, but it prevents injuries and keeps it fun.

If you insist on running, which is fine if that's your goal, I'd suggest using the same concept. Jog at a comfortable pace and gradually increase your distance. It may start at a 100 feet, but it will go up quickly.

You may have another problem which I wrote about in "Get your Shit Straight! http://amzn.com/B00HYE9Q0A It's free tomorrow, Jan 29th.
