This concept is interesting to me, but I don't think I'm the target market because I'm already a fast walker and walk more than 5 miles on a daily basis. Most of the time, I am making effort to slow my walking speed so others can keep up when in a group, rather than speeding myself up. I like the idea though, and if this takes off I could see it being helpful for a lot of people.
