I would like to get the stats of a selected interval on Garmin Connect, in particular the average heat rate, distance and speed. This is something Polar had 25 years ago; so quite bothered it's not provided by Garmin. It's something very helpful and I believe trivial to implement. One example would be if I want to compare several intervals of a bike climb that may not precisely fit the automatic intervals or the one(s) I set during a ride. As you can guess, this is not something I necessarily think (or want to think) about when I ride; rather something I like doing once I review my training results on the computer.
