@aaco11 - I have not been on that trail, but needing reservations and very open terrain (few trees) may I make a suggestion? Do one overnight in a forested area to start. Pick a Wilderness Area near you and check out a map for a 10 (or less) mile hike to a campsite. Try out your gear then walk out the next day. That is a good way to start.
I'm not a runner but you may need to reset your priorities from challenging yourself to just being present in every moment you are experiencing. Changing from goal setting to just wandering and exploring your surroundings and yourself can be life-changing.
