I have been a vegan for just over 2 years and LOVING it! My BF (who is also vegan) and I have a goal, that in 5 years we want to through hike the Appalachian Trail (which is a 2200 mile total hike). Therefore, since I am nearing 50, continuing with this lifestyle will help re-gain the energy I previously had in my 20's to be able to try to conquer that challenge.
