Experimented with how much running and walking I do

During my rest run yesterday, I experimented with how much running and how much walking I could do. During the race on Saturday I ran for about 10 minutes before I walked, although towards the end of the race, I reduced the amount of running.

I was curious yesterday to see if I could duplicate the amount of running, so I changed my running and walking times *from* 1:10 running and 0:50 walking *to* 5:00 running and 0:30 walking. I used those times for the first mile, but I became tired and reduced the amount of running to 3:00. and kept my walking to 0:30. I was able to use that amount of running for the rest of my run.
