Starting to incorporate a new angle to my fitness. I rode my bike to work today. I rode it home last week, bringing it in on the commuter train in the morning, and realized that riding my bike is a little faster. This is because I live right by a really nice, paved bike trail that follows a river for about 35 miles through the region and into downtown. The trip is about 20 miles, each way for me, and only the 3 miles by my office is on streets with cars. I ride a heavy mountain bike so it's a good way for me to burn calories, about 900 each way. I love to run for my aerobic fitness but one of my knees is shot to hell. The ride in was beautiful this morning. Lots of deer and wild turkey, and the sun came up around the 10-mile mark. It was very cool.
