It is interesting to read that two Garmins on the same ride would be so different from each other regarding elevation. I've considered getting one, but am holding off to see if my body can be encouraged to accept longer rides again....and I get over my current unease over riding in Indianapolis traffic.

As far as average speed, these days I fall just over 13mph and you know what? I am happy with that Neither my bike, nor I, am designed to be one of the fast gals. It IS encouraging that I no longer have to work really hard to get it up THAT high, which leads me to assume that if my body would accept a more traditional road bike that I would likely be faster - but that isn't my goal in riding.
