Cross Training

I have never been the person who does all kinds of types of exercise, such as running, weights, yoga whatever your pleasure is. Whenever I have done any training for a race I had found it hard to work, run and cross train. This is the first time I have fit cross training in, biking. I am the type of person that if it isn't convenient then I have a hard time sticking with it.
I started biking to work and it works for me as a cross training. The real reason I am rambling on about this I felt the benefits of cross training when I ran around Boulevard. My legs felt awesome, my cardio threshold has improved . I had such an awesome run, I even ran 10:1's and felt comfortable with them.
I have never enjoyed running 10:1's because my cardio could not stand it. I am looking forward to this summer of running (yes I said summer, warm weather).
