It's on the details page. Depending on the resolution of your display, you may have to scroll down to where you can see the tabs labeled Timing, Elevation, Heart Rate, Power, and Cadence.
Gradiant data would be very desirable. There are many rides I download into Training Center just so I can have a look at the gradiants...and that itself is not so great.
Also, in MotionBased you could save the image of the elevation profile, which was great for adding it to my website. Now that it's in flash you can't simply right click/save as. :(
Any thoughts on how to export the elevation profile graph?
