How Race Specific Workouts Will Help You Smash Your Personal Bests

Focusing your training and having a specific, measurable plan of action is essential if you want to conquer your racing goes. Very few runners are successful when they blindly cobble together workouts, especially in the last few weeks leading into an important race.

Too often, runners who lack a well-thought out plan derail their progress by performing 800 meter repeats with long rests in the weeks before a marathon or running 16 mile easy long runs two weeks before their goal 5k. However if you’re looking to perform your best on race day, whether you’re racing the mile or the marathon, it’s critical that the last four to six weeks of your training plan include mostly race-specific workouts.

If this is the first time you’ve heard the term race-specific, or you’re a veteran who wants to better understand the principle, listen up. In this article, we’re going to explore what race-specific training means, why it’s important, and how to implement race-specific workouts into your next training plan.

What does race-specific mean and why is it important

At it’s core, training is all about the principle of adaptation. Your body adapts to the demands you place on it by growing stronger and becoming more efficient. For example, when you run more miles, your heart increases the efficiency at which it pumps blood to working muscles and mitochondria (the aerobic energy power plant of the cells) grow in number and in size. Due to the principle of specific adaption, the closer you can perform exercise that mimics the exact demands you’re training for, the better you’ll become at that specific exercise.

Obviously, the principle of specific adaption applies generally as well as at a micro level. Meaning, running more mileage is generally going to make you a better runner compared to a session of kettlebell exercises. However, while all types of running will generally help you improve as a runner, race-specific training will produce better results at a particular distance.

As the name implies, race-specific training means training to the specific physiological demands of your race distance. While this might sound simplistic, the difference between the physiological demands of commonly run race distances can be quite different. Certainly, there is some overlap between distances in close proximity, like the 5k and 10k, but there is a large difference between the specific demands of the marathon and half marathon. Understanding these differences and applying the correct workouts is the founding principle behind race-specific training.

How does the principle of race specificity influence training

Consequently, in order to race your best at any distance, the last 4-6 weeks of training need to be primarily focused on race-specific training. Usually, this means running at or near race pace with short bouts of rest.

Unfortunately, some runners can take this concept too far. You can’t simply run 3 x 1 mile at goal 5k pace with 30 seconds rest each week of your training plan (or a variation of this workout) and expect to see a big improvement. This workout would be impossible in the early part of a training cycle and you would quickly stagnate.

First, you also need to build a high level of general fitness, or complementary energy systems, for race-specific training to be effective. Second, you need to constantly change the stimulus if you want to progress; meaning your body will quickly adapt to race-specific training and reach a temporary peak after a few weeks.

Therefore, race-specific training should start anywhere from 4-8 weeks out from your goal race. The precise starting date will depend on your experience level, training load, and how quickly you generally respond to workouts (some runners respond and adapt to training quickly, i.e. they “get in shape quickly” while others need longer build-ups).

Before you begin race specific training, you should build your base running fitness as high as possible by balancing the principle training components of aerobic fitness, lactate threshold, VO2max, and neuromuscular development. Like building a house, the stronger and larger you can build your foundation, the higher and more remarkable you can construct the peak.

The caveat of race-specific training

It’s important to remember that when you’re in a race-specific phase of training, your performances at distances outside your goal race range will suffer. Most runners forget this important lesson when they schedule tune-up races like 5ks and 10ks when training for the marathon or when trying to cap off a summer of 5k racing with a half marathon.

There is a balance in training that gets ignored in the four to six week race-specific phase of training. You’re sacrificing overall running fitness for better results at one specific race distance. If you’re targeting the 5k, you’ll be gaining speed endurance, but losing fitness to your aerobic system and lactate threshold. Conversely, when training for the marathon, you’ll rarely be running faster than half marathon pace and you’ll be constantly tired, which means you’ll lose the speed and VO2max required to run a good 5k.

Targeting your training to one specific goal is crucial if you want to run your best on race day, but it’s also important to remember how the training will impact your overall running as well.

Example race-specific workouts

Each commonly run race distance has it’s own physiological demands. However, designing a race-specific phase has two universal principles:

First, you need to progress to harder and more specific workouts week-to-week, just like you do in a normal training cycle. Your first-race specific workout should have more rest or be slightly shorter than you’re final workout. The goal should be to make progress towards running goal race pace with as little rest as possible in your final hard workout.

Second, you can manipulate two variables when making progression: interval distance and the amount of rest (the pace should almost always remain at goal race pace). So, the pace of each race-specific workout may remain the same, but the rest gets shorter or the interval distance gets longer. For example, your first 5k workout might be 5 x 1km at 5k pace with 90 second rest while your final workout 6 weeks later might be 3 x 1 mile at 5k pace with 45 second rest.

Here are sample race-specific workouts for the four most commonly run distances, along with an explanation of what is being targeted physiologically.

5k specific workouts

In a 5k specific training phase, your goal should be to improve your speed endurance – your ability to maintain a fast 5k pace for the entire race. You’re more than capable of running much faster than your current 5k pace for one mile already, so you need to work on holding that pace for 3.1 miles. My favorite starting workout is:

12 x 300 meters at 5k pace with 100 meter jog rest in 30-35 seconds (“jog” 100 meters in 30-35 seconds as your “rest”).

Once you get comfortable with this workout, you can run 12-16 x 400 or 600 meters at 5k pace with a 100m jog rest.

10k specific workouts

The 10k is similar to the 5k in that you need to hold a relatively fast pace for a certain period of time. However, the pace is slower and you have to hold it for twice as long. Therefore, 10k specific workouts require longer intervals. Here are two of my favorite:

5 x 1 mile at 10k pace with 45 seconds slow jog rest, hammer 1 more interval (to make 6 total miles) as fast as you can.

3 x 2 miles at 10k pace with 2 min jog rest.

Half Marathon specific workouts

The half marathon is a test of your ability to quickly clear lactate while running at a pace that is just above comfortable. Moreover, you need to train your legs to endure running hard for 13.1 miles. Here is my favorite half marathon workout:

3 x 3 miles at half marathon pace with 800m jog rest (jog at normal easy pace). This is a very difficult session, so you can start with 1 mile slow jog or reduce the volume to  3 x 2 miles.

Marathon specific workouts

Specific marathon workouts get a little tricky because it’s impossible to simulate the distance and intensity of the marathon in one run. The marathon requires you to be very efficient at burning fat as a fuel source to conserve carbohydrates while running fast on very tired legs.

Therefore, marathon specific workouts are often a combination of workouts throughout a week that build up fatigue and require you to run with low glycogen levels as opposed to one specific workout.

While hard long runs are certainly an important part of marathon training, my favorite workout is the 2 x 6 mile, which was made famous by runners at the Hansons Olympic Development Project:

1 mile w/u, 2 x 6 miles @ 10-20 seconds faster than marathon pace w/10 min rest, 1 mile c/d

The purpose of this workout is to run at your threshold pace for a total of 12 miles, which will help you: (1) increase your ability to burn fat as fuel source when running at marathon pace; (2) practice running on tired legs; and (3) simulate the “dead leg” feeling many marathoners experience after 18 miles. Likewise, the goal of the 10 minute rest is to get your legs stiff, stagnant and uncomfortable to simulate how your legs will feel during the latter stag of the marathon.

  1. my race is in 4 sundays from now ( not including the day after tomorrow which is a sunday) is it too late to this work out( marathon specific)?my plan is to do:
    33k this sunday(almost in 36 hours from now)
    37k next sunday
    26k sunday after
    18k MRP sunday before race
    race day sunday
    which of them could I replace with this workout?

  2. I’m attempting the 15 meter shuttle run and need to achieve level 9,4 and can’t seem to get past level 8,6. have you any tips please.
