Yes a small thing that, as a coach, would be personally welcome on TP, would be a recognisable pre-set “segment” ( for want of a better term) within analysis view. Much like on Strava where a segment can be created for record keeping of a particular section of mainly outdoor rides. I currently do this in “private” mode on starva to keep track of performance stats. I use this specifically for “test” routes. It’s particularly useful out doors in real world where the variations in wind/temp/surface etc can show up. Obviously a “section" can be highlighted on a complete route and recorded manually on a spread sheet to keep track of actual performances, but its cumbersome to review the same section of a ride/test over months of data.
The data on TP is much more valuable than other platforms, and would be good to have that option all in one place.
