I haven’t made any playlists, but here are some YouTube posters with various races I sometimes watch:
Again, if you’re prepping for a specific race, try to find a first person video of it. It works really well if there is, for example a 3 minute climb each lap and you are doing 3 minute intervals. Worst case, you can pause the video during your rest intervals and only play it during the ‘on’ intervals. So you pretend being on an attack, bridging a gap, trying to summit a hill with the leaders, whatever.
