Show (inline) who's fastest in a segment effort comparison over the segment
It would be great to see in the effort comparison, something showing when you're faster or slower than those you're comparing against.
On the map view you could have a single line showing green where your faster and red where you're slower.
On the graph view you could have dotted lines indicating where you're slower and solid lines where you're faster.
This would be an awesome way to visualise where you need to get faster vs someone you're competing with.
