8 Running Workouts to Build Strength and Endurance

Pronto a correre

When did running get so complicated?

I ask myself that all the time, usually when frustrated by a tough workout on my training plan or a confusing training concept.

Running is such a simple act — exactly what drew me to it in the first place — until you complicate it with drills, exercises, and complex workouts.

Of course, it probably comes as no surprise that the workouts on your training plan aren’t there just to piss you off. They’re included to help you run stronger, faster, and for longer distances.

Unfortunately that doesn’t make it any less complicated, so today I’m going to break down eight common running workouts, and share examples of how the work, and show you how to structure a well rounded week of training.

The Importance of Variety

Before we start wading through the details, let’s first talk about variety. More specifically, why variety in your training is so important.

There’s a little running phenomenon I like to call “Single Speed Running,” where a runner logs nearly all of his or her miles at the exact same effort. Day after day. That speed is usually around 75 percent of max effort — not fast enough to really make your body work hard and adapt, but too fast to build much endurance or count as a “recovery” run.

Sound familiar?

Chances are it does, since that’s exactly what most runners do.

Not only does Single Speed Running keep you from getting stronger; it also significantly increases the risk of injury: our bodies need variety.

We need uber slow runs just as much as we need Lightning Bolt style sprints. The variety works the cardiovascular system and muscles in different ways, and makes room for both strength-building and recovery.

By understanding the importance of each workout, you’re more likely to begin incorporating a variety into your training, and in return, reaping the benefits.

But first, those workouts need to become less daunting and confusing … the goal of this post.

8 Common Running Workouts, Explained (With Examples)

Below you’ll find a description of eight common running workouts for endurance runners. With each explanation, I’ve also included examples of how to put the workout to use.

Let’s start with the easiest:

1. The Easy Run

I’m putting the easy run first because it’s often the forgotten workout. But it’s also one of the most important.

Running at an easy pace builds endurance, promotes proper form, establishes routine and base mileage, and facilitates recovery. This type of run should be your most common, making up about 65-80% of your mileage (the percentage will vary depending your running philosophy).

The easy run is your aerobic workout, staying within heart-rate zones 1 and 2. If you’re unsure where that is for you, ask yourself this question when you’re running:

Can I keep a conversation going, speaking in paragraphs with full sentences?

Ask it out loud if you’re really unsure … just maybe not when others are within earshot.

If the answer is yes, you’re running in that aerobic, or easy zone, where your body and muscles have the energy and oxygen they need. For most runners, this is also where they should run the majority of their long run miles.

Sample Workout

  1. Workout: 6 miles at an easy, conversational pace. There should be no set structure or fluctuations in speed, but the hardest part will be resisting the temptation to speed up.
  2. Workout: 45 minutes at an easy pace. With this variation, distance doesn’t matter. You’re running for time instead of distance, so there’s no pressure to hit certain mileage.

2. The Tempo Run

The tempo run’s pace is often called comfortably hard. Difficult enough to require pushing, but comfortable enough to where you can sustain the effort. This is often around 85-90% of your max heart-rate, or just a hair slower than your 10K race pace, where short sentences are possible, but a full-blown conversation isn’t.

If you’re unsure of your paces, check out this pace predictor. It isn’t perfect, but will give you a ballpark pace to aim for.

We run tempo workouts to increase our lactate threshold, or that point at which your body switches from its aerobic system to its anaerobic system, and quickly fatigues thereafter. The higher your threshold at a certain pace, the longer you can sustain that given pace and build strength, speed, and endurance.

Sample Workouts

  1. Workout: 40 minute run with 3 x 5 minutes at tempo pace, and a 3 minute recovery in between. For this style workout, you’ll start the 40-minute run with an easy warmup, once warm, begin five minute tempo intervals with three minutes of rest, and repeat three times. Allow for time at the end to cool down.
  2. Workout: 90 minute run with 3 x 15 minutes at tempo pace, and an 8 minute recovery in between. A workout like this, with longer tempo intervals, is great for marathon racing speed.
  3. Workout: 60 minute run with 3 x 8 minutes at a tempo pace, and a 4 minute recovery, include hills during tempo sections. Tempo workouts can also include hill training, which is particularly helpful while training for a hilly race.

3. The Progression Workout

A progression workout is one of my favorites, and commonly found in marathon training plans. The idea is simple:

Start slow, finish fast.

Over the course of your workout, you’ll increase in pace by starting easy and finishing hard.

This progression in pace gives you a complete workout, using both your aerobic and anaerobic systems, without over-straining your body or requiring the same recovery time as a traditional speed workout.

Sample Workouts

  1. Thirds Workout: 15 minutes at an easy pace, 15 minutes at a comfortably hard pace, 15 minutes at a hard pace. In this workout, you’ll increase speed at every 15 minute increment throughout the run, starting at an easy pace and making your way up to a hard pace.
  2. Fast Finish Workout: 30 minutes at a comfortably easy pace, 10 minutes at a hard pace, 5 minutes all out. Here you’re maintaining the easy pace throughout most of the run, until the final 15 minutes when you increase to hard and then all out. This a great option for mimicking a late race push.

4. The Hill Workout

Hill workouts are often referred to as “speedwork in disguise,” because they offer many of the same benefits of a traditional speed workout, without having to run at top speed.

Running uphill is all about building that explosive power that promotes speed and improved running economy.

Running downhill works your quads, and builds strength in your tendons and joints.

Both are important to a well-balanced runner, so I recommend incorporating uphill and downhill days into training for any sort of hilly course. Just focus your workout on one at a time to get the biggest benefit and reduce the risk of injury.

Hill workouts can be done through hard, short sprints up (or down) a hill, or by running a sustained, gradual hill.

Sample Workouts

  1. Short Hill Repeats: 8 hill sprint repeats with light jog back down to rest, following a 3-mile easy run. This type of hill repeat will build explosive strength in the legs, and teach you how to attack shorter hills during a race.
  2. Sustained Hill Repeats: 5 x half-mile hill climbs on a gradual incline with easy run back down to rest. This is perfect when training for a hilly race, and builds endurance and strength on climbs and flats.

5. The Interval Workout

When you picture the quintessential speed workout, you’re probably thinking of interval training. A set distance, repeated a set number of times, at a set pace. Usually with a short rest period in between. Interval distances can be anywhere from 100 meters to a mile or more. Most marathon training plans focus on distances of 400 meters or longer, but the details are left to the workout creator.

Warning: Don’t piss off your workout creator. Interval workouts will likely be your most painful runs, the ones that leave you doubled over and gasping for air.

Most intervals are designed to build speed and strength by working your anaerobic system, or lactate threshold running, and focus on shorter distances of a mile or less. They can be run on a track or along a set loop.

Sample Workouts

  1. Workout: 8 x 400 meters on the track with a 400 meter light jog in between. Try to maintain a consistent pace for each of the 400 meter intervals.
  2. Yasso 800s: 10 x 800 meters on the track, with a light jog for the same amount of time it took you to run each 800 in between. The classic “marathon predictor workout.” I don’t believe it’s great at predicting race times, but it’s certainly a solid speed and endurance building option (and very tough).
  3. Workout: 2 x 1,000 meters with 2 minute rest periods + 2 x 800 meters with 90 second rest periods + 2 x 400 meters on the track with 60 second rest periods. In this workout you’re decreasing in the length of each interval, but increasing in pace.
  4. Workout: 4 x 1,600m with 120 seconds recovery in between. This is an endurance building interval workout. Aim to maintain a consistent pace for each mile, or increase slightly in pace over each interval.

6. The Ladder Run

The Ladder Run is a popular form of interval workout which climbs up, down, or both up and down in distance with a short (often 90 seconds or a 400 meter jog) rest period in between each interval. It’s a fantastic way to challenge yourself and mix things up, with a variety of high-intensity running paces and distances, all in a single workout.

On a track, increase in distance to the “top” of the ladder, or the longest distance interval, before decreasing back down. If you’re just descending the ladder, increase in speed as you decrease in distance.

Sample Workouts

  1. Up and Down: 400 meters x 2, 800 meters x 2, 1,600 meters, 800 meters x 2, 400 meters x 2, with a 400 meter light jog in between each interval. This is an incredibly tough workout, which tests and builds both your endurance and leg speed.
  2. Down: 1,600 meters x 2, 1,200 meters x 2, 800 meters x 2, 400 meters x 2, with a 400 meter light jog in between each interval. As you decrease in distance, you’ll increase in pace.

7. The Fartlek Workout

Ah, the classic Fartlek run. If you’d like to make fun of the name, be sure to pair it with a Jack Daniels joke.

The word fartlek means speed-play in Swedish, and that’s exactly what the workout is. An opportunity to play around with different speeds and distances in a single workout. This was my favorite workout day when I ran cross country in high school, and not just because of the name.

In a sport that requires plenty of structure, the Fartlek run allows your creative juices to flow. The workout is simple as this:

Intermix fast running with slower running, and vary the pace and distance of each interval. It could be as flexible as randomly picking a street corner, tree, car, or lamp post to sprint to, or run at a tempo pace for three minutes, followed by an easy pace for four minutes, and a sprint for one minute, and so on. There are no rules, other than to have variety in your paces and distances.

Sample Workouts

  1. Unstructured: 5-mile run with the final 4 miles consisting of Fartlek intervals. This is probably the most approachable workout here (other than an easy run), since you have the freedom to do as you please.
  2. Structured: 1-mile warmup + 3 miles, including four to six 5-minute surges each followed by a 2- to 3-minute period of easy running + 1-mile cooldown. If you need a little more structure to stay on track, this will still allow for flexibly and play, but is defined by set intervals.

8. The Long Run Workout

Your weekly long run is arguably the most important run of the week. It’s your chance to build endurance, and learn how to handle increased mileage both mentally and physically.

But for most people, that’s where it ends. They view long runs as only an opportunity to go long, not fast. I believe strategically planned long runs throughout your training are a great opportunity to work on late race speed, mimic the final push on race day, and toughen your mind to push through the fatigue.

By adding a workout element to you long runs, you’re giving them more structure and added benefit.

Now a few quick rules I recommend:

  • Don’t run a long run workout every week, but instead begin to integrate them into your training once you’re already comfortable with the distance.
  • Limit your long run workout pace to below a tempo pace, preferable somewhere around your marathon race pace.

During a long run workout, you’ll either increase from an easy pace to your marathon race pace, or alternate between the two.

Sample Workouts

  1. 1-2-3 Workout: After your warmup, run 1 mile at marathon pace followed my 1 mile easy, then 2 miles at marathon pace and 2 miles easy, 3 miles at marathon pace and 3 miles easy. Alternatively you can structure this with kilometers instead of miles.
  2. Countdown Long Run Workout: Take the difference between your easy pace and race pace and divide that by the number mileage of your run. Increase your pace or “count down” by that set increment each mile, so that by the end of the run you have steady increased your pace from easy to race pace.

Putting it all Together: What a Sample Training Week Actually Looks Like

Now that you’ve got the workouts down, let’s explore what a sample training week — which includes a number of these workouts — could look like. I say could, because training structure depends entirely on your distance and pace goals, skill level, and where you are with your training.

But let’s assume you’re training for a marathon, and roughly 10 weeks into a 16 week training plan. Here’s what your plan could look like:

  • Monday: Rest.
  • Tuesday: Tempo workout — 70 minute run with 3 x 15 minutes at tempo pace, and an 8 minute recovery in between.
  • Wednesday: Easy workout — 45 minutes at an easy pace.
  • Thursday: Track workout — 2 x 1,000 meters with 2 minute rest periods + 2 x 800 meters with 90 second rest periods + 2 x 400 meters on the track with 60 second rest periods.
  • Friday: Rest.
  • Saturday: Long run workout — A 17 mile countdown long run.
  • Sunday: Easy workout — 30-45 minutes at an easy pace.

As you can see, this schedule includes a lot o the variety mentioned above — both in distance, pace, and the types of workouts.

Challenge Yourself With New Workouts

Remember how we said variety was so important earlier?

Now’s your opportunity to take action. It’s easy to get caught up in a monotonous, comfortable rotation of just a few workouts and paces.

Mix it up. Try something new.

The variety just may increase your speed and strength, and reduce your risk of injury.

Which happens to be every runner’s dream come true.

  1. Thanks a lot. This was a very useful article. I agree wholeheartedly on the need to try to avoid the trap of the same moderate-paced run for every single workout, even though I fall into that trap at times. Do you think there’s ever a time to run what you describe as a typical 75% max effort run during a typical week’s training? Or should all training mileage consist of EITHER “Easy” running to promote those aerobic adaptations, OR “Speed/Hill” work to promote those anaerobic/lactate threshold/VO2 Max adaptations? For the goal of training for a distance race, that is.

    • Hey John, great question! There is a time and place for 75% max effort run, in the context of different workouts. For example, a progression workout could consist of miles in that zone. Same with a tempo workout. In general, I’d avoid running entire runs at that effort, and make sure it isn’t your “standard” speed.

      Hope that helps!

    Love this article! Thanks for posting and breaking it down!

  3. This is not news, yet it is a great reminder. Over the years I get distracted. It is always good to be reminded that there are basics. Thanks for the post, Doug. Your (with Matt) podcast was great to run to also.)

  4. Thanks Doug! After listening to the NMA podcast earlier this week, I tried my first Fartlek workout this morning. I started with alternating between lamp posts and then switched to running fast during the chorus of each song. What a fun way to start the day! And my overall time for my run was faster than usual.


  5. Interval training is definitely my favorite kind. I wish I had known about it sooner! I feel like it’s something they should teach in school, considering they always make you run a mile for time in gym class. If you were a chubby non-athletic kid in school like I was, that was always a very frustrating event, and you would think they would teach you how to do it well if they’re going to test you on it!

  6. Amazing article. Thank you! Any advice on how to incorporate these different techniques into a running week? Does it matter? Or is variety just the key?

  7. Hey Doug! Just wanted to ask when the article was posted? 🙂

  8. This is really amazing, am so happy coming across this post, i think right now am on the track. Thanks a lot.

  9. Ian Davey says:

    Thanks Doug, for all this time I think my zone 2 has been too slow. Great article all round to share with others.

  10. Keep inspiring us. LLL thanks on your sweat!

  11. I’ve always been one to say that you need to have variety in your workouts to get stronger and better. Your body can easily get used to something when you do it over and over again. The only way to really improve is to push your body and one of the easiest ways to do this is to switch it up every once in a while.

    Keeping your body guessing forces it to adapt to different situations making it stronger in the process.

    Thank you for this updated post.

  12. My Avg Cadence during interval, tempo or Long slow runs vary between 174 to 178. If I am conscious, I can increase my cadence upto 182. My Stride length varies between 1.35 to 1.48meters. My best FM pace is around 3h 16mins.
    Unbelievable that Bekele could increase his cadence from 190 to 216.
    Any tips on how to increase the Cadence? Thanks in advance.
