I'm not running this marathon to "race", or to break any time records (except my own), but I find that speed workouts are a great way to add variety to a training program.
Today's run was a 3x800 workout on the track. 800meters is equivalent to a half-mile or 2 laps around a standard size track. In this workout, the goal is to run 800meters above race-pace 3 times, with rest in between.
There are many recommendations regarding how many repeats to do, how fast to run them in, and how much rest to separate them by. This is what my workout this morning looked like:
400m - warm up
800m - above race-pace
200m - walk
200m - slightly below race-pace
800m - above race pace
200m - walk
200m - slightly below race-pace
800m - above race pace
200m - walk
200m - cool down
STRETCH.
The result was a 2.5 mile workout (by far the shortest I'll do all week), 24 minutes, 242 calories burned, average heart rate of 159 with a max heart rate of 190. Very different from every other workout during the week.
Hal Higdon agrees that speed training has a place in a marathon program: http://www.halhigdon.com/marathon/MaraAdvanced1.html
If you're training for any distance and need a 'change of pace' ;) hit the track and try this out. As someone who's not a fan of running small in circles, I can attest to the fact that this is short enough to make the track bearable.
