The first run I viewed in Garmin Connect I was able to get the red route line thingy on the map to turn multicoloured. It was different colours for different speeds around the route. I loved it as it really fed into my Geek-Girl-ness. However I'm now beginning to think I might have dreamt it because try as I might I cannot get it to do it again. Not on that run or any of the ones since.
Please tell me I didn't dream it and you know how it's done.
