Running Interval PR

>> Monday, April 17, 2017

Last week, I did my first real speed work in many months. I went out for a simple 2x2 mile interval run. I figured it was a good hard effort run without TOO much quick/sharp speed 2.5 weeks before my first duathlon of the year.

My first interval had nice descending 1/2 mile splits mainly because this was the first hard running I'd done in a while and I wasn't sure what I could do:

- 2:59.40, 2:56.70, 2:53.73, 2:49.10 = 11:38.93

And as I started my final interval (after 3:00 of walking), I told myself that I was NOT going to descend this one - I just wanted to run it HARD all the way through. And the splits look like that: they look a bit like a race where I start a bit harder, slow up a little, and then push to the finish:

- 2:51.19, 2:53.77, 2:50.87, 2:48.66 = 11:24.49

After my workout, I tweeted about it, and Coach Jen started tweeting back. (She was the one to first give me this workout nearly 7 years ago.) Here was our conversation over the course of a few hours:

I was SHOCKED to realize this was faster! In 2010, I was in better running shape (I'd just set my 17:11 5K PR earlier that year), AND I was really trying to KILL Coach Jen's workouts as she was trying to get me to break 60 at the 2010 TC 10 Mile. Those are 2 BIG reasons why I just assumed I was faster in 2010.

I dug and I dug, and I think that last week was the FASTEST I've EVER done that workout!! Here are links to a few previous (relatively fast) 2x2 mile workout posts:

- First time with Coach Jen (flat by my parents farm) in 11:48 and 11:34.
- A year later in 11:26 and 11:38.
- PUSHING HENRY in the stroller in 11:36 and 11:37.
- Pushing bigger Henry in the stroller in 11:46 and 11:42.

So I didn't realize that last week's 11:38 and 11:24 were so good compared to previous workouts!

SIDENOTE: Here's cute 9-month-old Henry back in 2012 from one of the links above after we'd done our first 2 mile interval before starting the 2nd:

He loved the speed!

So last week I did them on the Greenway Trail, which is quite flat. Normally, I do them along the Mississippi River where I have a decent little hill either just before the end of each interval or just before the half-way point of each interval (depending on how I run them). So the 2nd time I did them (linked above) in 11:26 and 11:38 was actually probably faster than last week just based on the fact that I did those just a bit slower but while working in some small climbs too.

Still, pretty happy with that speed! I was NOT expecting that! Maybe stringing together some decent training weeks is starting to add up! (I've now had a swim, bike, or run 62 out of the last 65 days! That's looking back to February 11th!)

Oh, and for the record, this does NOT mean I'm in the best running shape of my life. I don't have the short-end speed I used to, and I don't have the endurance that I had a few years back. I think this workout just happened to be a perfect balance that highlighted my current strengths. I'm not about to go run a 58:00 10 mile or sub-17 5K. :)
