Upped the resistance levels significantly and lowered the target speed to 13 mph. My peak heart rate was actually just a bit less than before. The last ride seemed harder in many ways, but this one seemed like a better workout. Perhaps that is because it is more even throughout, similar to jogging, and less like interval-training. That may or may not be a good thing.
