"Fartlek" - Swedish for speed-play - runs are designed to inject additional stimulus into what is otherwise a base or endurance run. These short bursts of speed help teach your body to recover while still maintaining a strong pace. The key with a fartlek run is that you surge from a solid endurance pace and then return right back to that pace. You should not need to slow down below your base pace to recover. Consistent fast running is a key part of building the sort of anaerobic capacity and power you will need to smash your 5K PR.
Really easy runs are important for keeping your frequency up and the body's rhythm flowing. Do not push the pace here. Just relax and keep the legs turning over. These sorts of runs are great to do on a treadmill because it will force you to hold an easy pace and also it reduces the pounding as opposed to concrete/asphalt.

Hill repeats are really speed work in disguise. Hills are a great way to build speed and power on tired legs. The power required to run up a hill is the same as to run fast, but the leg speed can be lower. A grade of about 6-8% is ideal, but you can play with speed and gradient to keep the workout interesting.
Long steady blocks at the top of Zone 2 help develop the endurance that you will need through the middle of a 5k. After a fast open, you will need to run strong through the middle in order to kick hard at the end.

Having a big base is essential for being able to handle the fast start, surges with terrain and competition, and fast finish of a 5K. Being able to run a long way without tiring is a critical part of being able to run much shorter distance at a sustained fast pace.
Being able to push for sustained periods over threshold and then to recover while still running fast is an essential physiological skill for the 5K racer.

Over-unders help develop your ability to surge and recover - repeatedly. This helps to improve economy and makes the sustained high effort - just a notch below the surge pace - feel much easier.

Hill repeats are really speed work in disguise. Hills are a great way to build speed and power on tired legs. The power required to run up a hill is the same as to run fast, but the leg speed can be lower. A grade of about 3-5% is ideal, but you can play with speed and gradient to keep the workout interesting. Longer hills like this challenge your ability to maintain power and - especially form - as you get tired. In the second half of each climb, make sure you keep your shoulders back and your chin up.

After last week, you should have a better idea how to pace these high intensity sustained efforts. This time we lengthen out the first interval to 1.5mi and then shorten the rest and then do another half-mile at close to your goal pace for 5k. This will help further dial in that pacing.
A nice easy run to help keep your rhythm. Make sure you head outside for some of these runs as well. The treadmill is a great training tool, but it is important to get used to pacing on the road as well.

With some experience with two-mile/3200m time-trials, we add a layer of difficulty on with some extended intervals after the 2mi effort. The goal here for these intervals is to hold the same speed OR FASTER as you did for your 2mi effort. Long and very easy recovery between.
With a bunch of hard, sustained efforts in your legs, you should have a better idea how to pace these high intensity sustained efforts. This time, it is a straight two-mile test at close to your goal pace for 5k will help dial in that pacing.
