SportTracks
I’m sure there are many bits of software out there to track intervals.
My favourite is the FREE SportTracks software. It does almost everything I need it to do, including more.
And even though what it can’t do for me is small, free add-ons can do even those bits. Eg the marvellous Performance Predictor.
I compare this to the almost useless software with Garmin and the pretty decent software with Polar.
