While there is no magic workout, the long interval workout is mandatory if you want to run longer and faster. There are many iterations of the long interval, but to me, there is nothing like the mile-repeat. It is challenging yet not unconquerable. It is long but not unending. You can start with a few reps and progress to as many as you can handle. If performed at the right pace, you can recover and do it again right away. And if all that wasn’t enough, it hits all the systems.

I remember reading Alberto Salazar’s autobiography many years ago. He was adamant that this was his key workout from his high school days to his time at the top of the world’s elite marathoners. Since then, I have performed it and prescribed it to my trained runners. The results have always been palpable.

 A mile repeat improves your cardiovascular system while upgrading your endurance and speed. Cadence is increased, mental toughness is developed, and physiological indicators such as VO2Max and lactate threshold are enhanced. Because you are performing at a high rate of energy consumption, the brain ensures that wasted movement is kept to a minimum, resulting in better running form.

 Mile repeats are more than hauling ass one mile as fast as you can go. Anyone can do that. The key is to understand the purpose of the mile you are running. This will determine the pace and effort in which it should be performed.

 Benefits of mile repeats include:

 ► Speed Increase: When performed at race pace or even faster, you are stressing your multiple systems and teaching your body to withstand harder efforts for longer. You are also teaching it how to recruit additional muscle fibers when the usual ones are beaten up.

► Pace learning: Because we run mostly at an easy pace to maintain and improve our aerobic base, learning how to reach, feel, and maintain our race pace is key. Mile repeats are a perfect way to get there before starting to extend the race-pace mileage. The key is to be constant at the desired pace and not believe that faster is necessarily better.

► Endurance improvement: Running roughly at the pace you could sustain running all-out for one hour (Tempo) will improve the amount of oxygen you can consume at max effort (VO2Max) and push the line in which your body is unable to use lactate to fuel itself and become unable to clear it, thus triggering fatigue (Lactate Threshold).

In a recent article in the Marathon Handbook website, Amber Sayer stated a great point to be considered when executing this workouts: “The longer your race (half marathon or marathon, for example), the earlier in your training program you can do mile repeats at race pace, because a mile is a significantly smaller percentage of the overall distance.”

And mile repeats don’t need to be performed on a track necessarily. I wrote a post on that issue, which you can read by clicking here. 

 Executing your mile repeat workout safely and properly requires certain preparation:

 ► Know and understand your workout: It is imperative to be prepared for a difficult workout, so you won’t have the mental space to improvise. Know how many reps you have, what your recovery time is, what is the pace and what is the purpose of this workout. This will predispose you to a successful effort.

► Warm- up properly: You will be performing a hard workout. You must prepare your body for it not only to avoid injury (as if that weren’t enough reason) but also to make sure you can reap maximum benefits. If you want to read more about the value of the warm-up, click here.

► Keep it constant: Running the first 400 meters in 1 minute, 2nd 400 in two minutes, 3rd in 3 minutes, and 4th in four is not a 10-minute mile. It is a shitty, worthless mile. Maintain your effort and pace as consistently as possible. This is what’s going to make you better, not a one-off 400-meter stretch at world record pace. Consistency and frequency are what will reap the most benefit for your effort.

► Continuous movement: You will be tired once your mile is done. Of course, don’t stop, collapse, or sit down. Keep moving. This is the closest you will replicate the demands of a race. I recommend a light jog in between miles, but if this is too much, walk until you catch your breath and then jog. The point is to continue moving forward as you recover and get ready for the next rep.

► Focus on your current rep: Stay focused on the mile repeat you are executing right now. Don’t dwell on the last one being too fast or too slow. Don’t think about what will happen after this one. You are executing this one now, and it must be executed properly. Thus, it is the only one that matters.

► Cooldown: You performed a hard workout. Your body is in overdrive. You are tired, exhilarated, most likely amid a runner’s high. This is not the time to jump in the car and go home. A mile or two of easy running will help blood flow. Muscle recovery, and removal or metabolic byproducts. If you want to read more about the value of the cooldown, click here.

 Make sure you add this workout to your training repertoire. The benefits will surprise you.
