Training Load and Recovery load from cycling and running

To survive this winter, I have decided to combine running and cycling again, to strengthen my heart/lungs and my core. This means that I need to combine the stress of the running activities and the cycling activities. I was expecting that the aggregation of the running account and the cycling account would lead to one XPMC, but it seams that we still have two seperate charts. Have I missed something here? [by the way, both running and cycling are power-based activities]. Keep up the good work!
