On Newsstands now, Wired - July 2009 - Athletes - Track your Data

As software developer who works on a site that does exactly this,
I was very pleased to see the cover of Wired this month (July 2009) covering
Athletes who now Track their data using Gps devices, heart rate monitors, etc.
and also use different websites similar to mine (http://www.EnduroTracker.com )to plan, track, and analyze their data.
