Currently duration, TSS, and IF are showed on the calendar cards. Being able to expose kJ(cal) on the calendar view would be helpful for planning pre-ride and in ride nutrition.
For what it’s worth you can mentally get close by looking at the IF and duration, knowing your FTP.
For instance an hour at my FTP is around 1100 Cal, so an hour workout with a 0.66 IF is close to 0.66*1100
Or I can click on the ride and it’s already calculated for me. I just want to eliminate two clicks to surface more useful information.
