03-12-2013 Ride

Stationary bike at work for 45 min in the morning before work, listening to music on my phone.  I inadvertently entered level 15 and didn't notice it until I felt that I was really struggling to keep my cadence.  I stayed with this level, and it was a very different workout, more focus on strength-building than on cardio.

Level = 15
Avg heartrate = 129 bpm
Calories burned = 520
Distance = 13.3 mi
