Edge 830 for running

Hello everyone. 

My Maine activity using edge 830 is cycling. Lately I've picked up some jogging and I'm pretty amazed how edge 830 is capable of recording this activity. The GPS is pretty decent and it measures accurate my running tempo. Using additional downloaded apps I can even get my running pace displayed. I'm wondering if i can get my VO2max estimate for running while using edge 830 (a post-edit my activities recorded and change from cycling to running). After a few runs I don't get an estimate od my VO2max for running. Od Edge capable of creating such estimate for running?
