Currently I only know if I set a new section personal best achievement or beat one of my friends on a section time AFTER the ride is over. I would suggest adding a third screen that you can toggle to for competitive. This screen would show you the current section you are in and how you are tracking towards beating the current best time, and if you have a route selected then tracking that separate to the section for your overall time. Making this available on the map would be fantastic, with the option to overlay a ghost version of yourself on your previous best run for the segment, or even allowing you to view a ghost version of your friends so you can see what sections they are getting more speed on. I believe you already have all of the data to do most of this, if not all of it with some minimal development cost.
