Honestly, it really isn't another gadget, just an application for the
iPhone that is super cool. Using the phones GPS system it keeps track
of your distance traveled, elevation gain and loss, etc. Afterward you
can upload the info to the TrailGuru site and it will produce a map
for you, showing your route. Not bad, especially considering the
application is free. I was surprised to see that the short 1.25 mile
hike gains well over 1,000 vertical feet. Trails that steep aren't
east to climb, or descend for that matter.
