[Andrejs Ozolins]

I can add another climbing number to those: DeLorme's Topo software says 
you climbed 2,763 feet.  It's interesting that your GPS is closer to 
that number than the MapMyRide because GPS units are not particularly 
good at measuring vertical movement. But, behind the disagreement is the 
fact that your measurement of climbing depends on how you define 
climbing. If you count every single inch of vertical movement as a 
climb, then you'll come up with astronomical figures for a whole ride. 
In practice, the rules can be be defined to give a range of results -- 
at what minimum rise to start measuring; what increments to measure, 
etc. Anyway, my impression is that the Topo figure of 2,700 is probably 
closest -- over the years, seeing elevation figures from watches and 
bike computers as well as other people's reports, the DeLorme estimate 
has always been pretty much  in the ballpark.
