is there an area that shows watts per kg?
Not directly. A few of the athlete profiles are listed in W/Kg (Road Sprinter, Puncheur, GC Specialist & Climber). You can find these in the RANKINGS tab of the main page. Hope that helps!
If you set your profile as Climber or GC you will see Watts/Kg On your “My fitness” page
Wouldn’t it be better to to allow to switch between watts and watts per kg on the rankings chart? For me the chart is pretty useless. For durations which are shown as W/kg I’m around 50%. For those in Watts I’m around 25%.
