What happened at 30 minutes? Looks like you lost signal to the power meter / computer.
I have been considering a Stages for one of my mountain bikes, riding Quarq on the road.
Ha. That wasn't power meter. That was a broken chain, waiting for a pick up! Fixed then drove back to the trail. So far so good with stages. Will see with race data tomorrow
