I have been biking since last March. After putting 1900 miles on the bike and finishing a 111 mile Century plus (almost 9 hours, but still), I have decided the lungs need to be in better shape.

Bought good shoes and tried it this morning at the Y on the treadmill. 9 min run, varying speed from 4.2 to 5.5 MPH, then a min. of walking, then repeat 2 more times. Finished with 5 more min at 5 MPH. Honestly it felt surprisingly good. My son's i-pod made it possible - Ramones and Arrowsmith are great for running.

Did I do it right? Tomorrow it will be raining cats and dogs, and I though I could do an easy 20 min run at 4.5. Does this make sense? I really seem to need the endorphins every day.

My plan is to do it a few times a week when it is too cold or rainy to bike.

Is there a book or web site that would help? I only have found starting from Couch Potato advice and marathon prep. I fall somewhere in between - really just want the running to help me be a faster biker with better breathing.
