I have no idea if this link will work for everyone or not but here we go. Click on this Garmin link which will take you to my bike workout last night. You should see something like this:
Click on the 'play' button at the top and watch the map as you see me cycle around my local lake. Pay special attention to the bottom where you see Total Time, Total Distance, Elevation, Speed, and Heart Rate all play out in real time. You can see when I'm climbing and fighting the wind and when I'm descending and have the wind at my back.
Pretty neat stuff! The technology....not my ride!
