Building it back up

Since I had no kids at home yesterday, I went to the YMCA early and stayed longer without going to the pool than I would have normally. I had already made the decision to do some interval running/walking on the treadmill, so I was looking forward to it. My plan was to run 8 minutes and walk 2 minutes 3 times for a total of 30 minutes. So, I got on the treadmill, found a comfortable pace and started running. I hit 8 minutes and felt great, so I decided to go for 2 more. Still felt great at the 10 minute mark, so decided to just go as long as I could running. I hit 15, 17, 20, 22, and tried to push myself to 26. At 24.5 minutes and 2.04 miles, my body said no more...you've pushed me farther than I wanted to go already. So, I stopped. I was very excited to run that long and that far since it's been a while. I decided to stay longer and do some lesser impact exercise. I cycled for 20 minutes and then headed home. I'm going again tomorrow to run again and possibly do some other machines. I'll have Kristin with me, so I may not work out as long before we get in the pool, but my goal is 30 minutes on the treadmill.
