The edition is a two-fer announcing Zwift Running and the Milestone Pod (the best running pod for the money). I would sign-up for Zwift Running now and check it out while it's free!
Looking for a win/win? Check out The Don Kit by Endura, all profits go to help Tim Don recover. Also, the book of all books for age group triathletes who want to go the distance while juggling work, family, etc.
