3.5

I did almost 3.5 this morning. I started out with intervals of 1:30 running and 1:00 walking. After the second mile I switched to 1:00 running and 1:00 walking. I think my perfect mix is probably somewhere between there. I think I will start adding 5 seconds at a time to the running, and figure out what helps me go the farthest without getting too tired at the end. I'm taking tomorrow off and doing another 3.5 on Sunday.
