When I hit a hill for exemple, I would like to start a lap that tells me the lap information such as time, average power, etc. So, if I need to do that hill in 5 minutes at 300w, I have the information. When I'm finished, I can either save the lap data or delete it, then I return to my normal ride information or screen.
Is this possible with my Garmin Edge 840?
At the moment, to do this, I need to stop and save my ride information and start a new one just for that hill. Pretty annoying.
