Time Trialing

My plan for yesterday was a time trial.  I've been having a little pain in my hip, so I took yesterday off and combined the time trial with today's 4 easy miles.  Here is the explanation for a time trial:

Go to a track or any one-mile stretch of road. After a 10-minute warmup, time yourself while running four laps (or one mile) as fast as you can. Note your finish time, then cool down with 10 minutes of walking and jogging.

Do the same test every month and compare the results; as your fitness improves, your time will decrease.

Here's how it went for me:
I warmed up for a mile at 9:56 pace.  When my Garmin hit the one mile mark, I upped the pace.

Time Trial mile - 8:36 pace!  This was a relatively flat stretch of road, not a track, and definitely as fast as I can run at this point.

Mile 3 - 11:05, I took a short walk break.  Just before I hit the 3 mile mark, another runner passed me.  He was probably a foot taller and definitely faster.  I decided to see how long I could keep up...

Mile 4 - 8:53.  I kept the other runner in sight but he kept pulling away.  I'm guessing his pace was about 8:00-8:15.

Mile 5 - 9:18

Total - 5 miles in 47:52, 9:34 pace.
