Guys, is there any option to add more pace partners? For example 1,5W/kg is to easy but 2,5W/ kg is to hard 
Maybe 1,5W 2W 2,5W 3W 3,5W 4W and 4,5W for pro horses? WHAT DO YOU THINK?
I don’t disagree but as a workaround try a gravel bike or MTB with the 1.5, it will be significantly harder. Or just change your weight until your preferred watts gives an appropriate speed.
I would rather see more dynamic pace partners… 2w/kg on flats 3w/kg hills = avg 2.5w/kg
