Spin class last night. One hour and two minutes of intervals. Max HR was 90% of max and average was 72% of max. HR monitor says I burned 776 calories. I am going to be spending the summer working on losing weight and building more strength in my legs to improve my speed on the open road for next year. No big road rides planned until July 18...the Katy Flatland Ride. We are planning to do the metric century (100km/62 miles), but we will have to see how hot it is that day. Last time I did this ride it was nearly 100F by the time I finished.
