Speed Work for the Track!
The track… some of us may jump in excitement (like myself) in anticipation of the pain, suffering, monotony of endless circles, and some of us may cower in fear at the thought and come up with every excuse in the book. Truth in the matter, regardless of which you are, training on a track can improve your running by leaps and bounds (no pun intended) if done correctly. Although one can effectively train without visiting the dreaded oval, there is no environment like the track conducive to a quality interval session. You don’t need to visit the track every day to reap the benefits, just once a week is plenty, and if knowing doing this one thing will help improve your long distance running doesn’t motivate you to suck it up and suffer just once a week, than I don’t know what will.
There are four main groups of interval sessions – short, middle-distance, long, and mixed. Short intervals are typically 100-400 meter segments run at an all out or nearly all out pace with long (2-3x the duration of the interval) recovery periods. These sessions will increase raw speed, stride power, and running economy – focus = SPEED. Middle-distance intervals are typically 600-1200 meter segments and are run around a 5k-10k pace with a 3-5 minute recovery period. These sessions will stress your body’s ability to consume oxygen building aerobic capacity, recycle lactate, and resist the physiological causes of running fatigue – focus = VO2 MAX. Long intervals are typically 1600 meters (1 mile) to 3000 meters and are run around a 10k-Half Marathon pace, usually only a few repetitions completed with a shorter recovery similar to middle-distance intervals. This pace tends to be close to or above lactate threshold for most runners, and training at or near threshold increases the body’s capacity to recycle lactate for muscle fuel, increasing your lactate threshold pace on a long-range spectrum – focus = LACTATE THRESHOLD. Mixed intervals are exactly that, a group of two or more interval lengths explained above. Because they do not have a single focus or specific intensity, they are not ideal for boosting specific running components and are usually most effective when used to maintain fitness in the final weeks of training before a race.

Have fun, and learn to LOVE the track and all the pain that accompanies it :]
On the mixed interval workout should the 400 meter recovery lap be a walking or light jogging HR Z1 pace?
Your main goal on that recovery is to bring your HR back down, if you can do that at a jog and that is a comfortable recovery for you, then great! If not, walking would be perfect!
