Running Intervals: 3/24/11

It's been about 3 weeks since I last did any interval training.  Looking back, I believe it was March 2.  I'm following a slightly different plan now.  Back then I was running really fast for short stretches and resting for longer periods.  Today I did 2 minutes fast followed by 1 minute of slow jog. 

It was a little cooler this morning that it has been so I threw on a long sleeve shirt before heading out.  There wasn't much wind so the lake was glassy smooth.  I started out with a 5 minute walk, then a 1 mile warm up at a fairly slow jog.  After hitting the lap button to start the intervals I had programmed into my Garmin, I picked up the pace, attempting to average around 8:30/mile.  I nailed the first one with a pace of 8:31/mile.  Of course, it wasn't a steady 8:31/mile.  At one point I was somewhere in the 7s and then somewhere in the 9s.  Still, I was pleased with the decent pacing.  After that my pace was all over the map.  8:31 ended up being the slowest interval I ran, though.  My fastest was the last on at 7:43.  That's pretty amazing to me, because by this time I was beat.  In general, my last 5 were faster than the first 5.  It's good that it's become second nature to pick up the pace in the second half of my runs.  I also noticed a trend toward running faster during the slower rest portions as the workout progressed.  It's funny because I really felt like I was much slower.  In reality, my last rest was more than a minute per mile faster than my first.  Once that was over I was still about a half mile from the car so I jogged back at just under 10:00/mile.

Overall, the run wasn't nearly as hard as I had anticipated.  Not that it was easy.  I definitely pushed myself, but I feel like I could have pushed myself quite a bit harder.  Either way, I'm sticking to this plan for the next 4 weeks or so until my next 5K, theoretically on 4/30.  I'm certain it will improve my time, but I'm not sure by how much.  I'm hoping for a sub 27 minute time which means I'll have to run an average pace of 8:43/mile.

Today's Stats:  I did a total of 4.74 miles in 44:48 for an average pace of 9:27.  Considering all of the slow jogging that was thrown in there, I was really surprised at that pace.  It was one of my fastest training sessions, edged out by only a couple of shorter runs.     

Next up:  Another swim tomorrow morning and a long run on Saturday if I can fit one in between storms.  According to the plan, I'm supposed to run for approximately 3 times what it took to finish my last 5K.  That's 1.5 hours.  I'm not supposed to worry about pace, other than keeping it steady and continuous.  If I want to do a full 90 minutes, I'm going to have to definitely try to keep my pace slow and easy.  I might venture elsewhere for this run.  I would have to run the length of the park about 3 times to go for 90 minutes and I think that might get extremely boring.  I might just head out the front door and see where that takes me.

Bonus:  I passed my 2010 mileage today!  I'm on pace for over 500 miles this year.  If I decide to up my mileage to train for a half marathon in October, I could possibly double that.
