Day 3 Interval Training

So it is day 3 of my 6 weeks training to running a faster 4/5 mile race.

Today's mission: interval training day.
I had to do 5 X 400 M hard and in between recover with walking and/or jogging.

How I did: It was hard to guage how hard I should go. Every so often I would go very hard and every so often I didn't go as hard as I would have wanted to go. During 1 lap I actually gave up about 100 meters before reaching the end. I also almost gave up before my last 400 M but thanks to my running buddy who was still going around the track doing her Couch to 5K training, I motivated and wrapped it up. I did 5 X 400 M as hard as I could.

How I feel now: I feel good now though my left leg felt a bit shaky. My left hamstring especially inner has been a cause of concern and it is still worrying me.

How to improve: I need to stretch better. The one thing I suck at. I also need to figure out when I will fit in a strength training session in during the week. I also may need to gauge and figure out how fast I should be going.

Notes/feelings: I'm glad to be back out there and running. I am looking forward to seeing my time improve. I will take it easy the rest of this week. Sunday I have a long run of 5 miles...let's see how that goes. You think it should be cake after a 1/2 marathon but I still am hesitant when the mileage is any more than 4 miles. :)
