Heart beat and the running path

After a break for about two years, I started running again on the weekly basis.

While checking the length of my running path through Runningmap.com, I was wandering how come the manufacturers of heart beat rate meters and services such as Runningmap don't cooperate. I would love to have my pulse data connected to the ups and downs on the path. Runningmap has elevation meter and Polar has several models which can transfer the data to a computer.

All this data then could be transferred to some social network service for others to admire.
