As an advocate for all things Vega, I follow the community. They recently posted this interview with a triathlete and ultramarathoner on running ultras. It is well worth a read. You can find the post here: http://www.vegacommunity.com/profiles/blogs/ultra-running-and-me?cid=FB. Hopefully this will inspire you to find a goal in your life that you can strive to attain that will stretch you beyond what you think is possible for yourself.
