How to Train Like a Pro Endurance Athlete

Endurance sports are changing rapidly.

There are more races in more locations than ever before. More and more beginners are dipping their toes into swimming, biking, running, OCR, and triathlon.

2025 will look completely different than it did even a few years ago. And that means there’s not only a ton of opportunity to compete, but to do well.

Focusing on making a few simple changes will help you stand out from the crowd.

I know this because I spend so much time researching the cutting edge of athletic training, strength and conditioning, and peak performance. In the last year alone, I’ve read over 50 books and 100 endurance sports performance articles.

I’ve incorporated that research into my training, and that of my clients, and the results speak for themselves.

In this article, I’ll discuss the top five strategies for training like a pro endurance athlete in 2025, even if you’re just starting out.

If you want to thrive in your sport, this is where you have to focus.

Strategy 1: Stick To a Plan

The first strategy, and the most important one, is to follow a plan.

I know you’ve heard it before, but this is the best way to start training like a pro endurance athlete. You probably got away with winging it up to this point in your sport. 

But if you really want to improve, you have to switch your mindset from endurance workouts to endurance training.

What’s the difference? Workouts without a plan are just exercise.

It’s fine if you’re just trying to improve your fitness. But if you want to compete, you need a training plan that at a minimum:

• Trends toward increased training load – meaning you progress to more volume over time.
• Transitions from general to specific – meaning it starts to resemble your competition as the competition approaches.
• And balances recovery time with intensity. Professional athletes don’t just have recovery days; they have recovery weeks or even months. These recovery periods are strategically implemented to allow for training adaptations to occur.

Strategy 2: Consider Polarized Training

The second strategy to train like pro endurance athletes is incorporating A LOT of low-intensity work.

You’ve probably heard your favorite influencer say something like, “You have to run slower to run faster.” 

This is only part of the puzzle. What this refers to is polarized training or 80/20 training. This means 80% of your training is done at low intensity, and 20% is at moderate to very high intensity. The most common way to measure this is using heart rate zones. 

A lot of pros use this style of training. 

Here’s why.

Lower-intensity training has a lower risk of injury. And elite athletes do not want to get injured.

Lower-intensity training also allows you to build an aerobic base while working on proper form. That’s why many pros use low-intensity training for up to 90% of their off-season sessions. The idea here is to increase your body’s efficiency, meaning you can run, bike, or swim faster at a lower heart rate.

Building your aerobic engine takes time but is worth it in the long run.

Most beginners are training at a higher heart rate than they realize and need to spend more time in the lower heart rate zones. Similarly, beginners tend to under-train at the other end of the spectrum. At least some of the other 20% of training must be performed at maximal or near maximal effort.

Incorporating some high-intensity work like sprints and threshold runs is a must.

Strategy 3: Use Strength Work to Improve Endurance Performance

The third strategy you can implement to train like a pro is following a strength training program tailored to your sport.

I cannot tell you how many times I’ve seen beginners jump into an endurance sport while continuing to train like bodybuilders.

Weight lifting twice a week is not the same as training for athletic performance.

I’ve also seen endurance athletes spend 15 minutes in the gym using nothing but lighter weights out of fear they will put on too much muscle mass.

Both of these strategies miss the mark.

Pros follow a strength and conditioning program that compliments their endurance work.

Write that down; your strength work should complement your athletic performance. 

A well-designed strength and conditioning program will consider the athlete’s ability and include aspects of injury prevention, foundational strength, power, and sport-specific movements. 

Invest in your own research or hire a strength coach or personal trainer with a background in athletic training. This is one of the easiest ways to get ahead in your sport and show up ready to go on race day. 

Strategy 4: Measure, Measure, Measure

The fourth strategy is to measure performance.

Beginners really struggle with this for two reasons. First, they don’t know what measurements to take, and second, measuring performance can be time-consuming and difficult.

But it is worth doing.

Here is the simplest, most straightforward example of taking performance measurements.

If your goal is to run your first 5K, then at the start of your training program, you will run/walk a 5K and see how long it takes. Every three to four weeks, run another 5K and track your time. Everything you do, every run, workout, and recovery period, will be designed to reduce the time of your 5K time trials. 

Remember, the best time to take measurements is at the start of a training program. 

If you never measure your performance, you will not know if you’re progressing or if your training is working.

Remember, the performance indicators you track will vary depending on your sport and fitness level.

Strategy 5: Focus On One Goal

The fifth and final strategy for training like a pro endurance athlete is to focus on one goal at a time.

Pros hyper-focus on their sport. They live and breathe it. They follow the sport religiously. They watch competitions. They attend events they aren’t competing in. They study it.

This is a great way to learn the ins and outs of a sport.

Beginners and amateurs, however, are plagued with shiny object syndrome.

I am just as guilty of this as everyone else. I see new races or fitness challenges, and I’m dying to try them.

It’s something I’m working on.

There’s absolutely nothing wrong with trying new things. But if you want to train like a pro, then it’s a good idea to focus on one objective.

Also, professional athletes don’t compete in many endurance events. Most strive to peak in a handful of events throughout the season.

They have an intense singularity of focus. Integrating a more singular focus into your training plan is an effective way to boost performance.

Follow the pros of your sport. Watch the competitions. Immerse yourself in the sport and watch the difference it will make in your performance.

How to Train Like a Pro Endurance Athlete

In 2025, you’ll see many more beginners and amateurs taking their training seriously. It’s a great time to get into endurance sports because more resources and races are becoming available to athletes.

The competition’s getting stiffer, so let’s review how you can up your training game.

• Follow a training plan tailored to your goals and specific needs. This is a must! If you only do one of these steps, make it this one.
• Incorporate more low-intensity sessions and very high-intensity work. Most amateurs spend too much time in the middle and not enough time at the lower and higher ends of the intensity spectrum.
• Follow a strength training regimen tailor-made to improve your athletic performance. 
• Measure your performance. You’ll never know if your plan works if you don’t track your progress.
• Immerse yourself in your sport and focus on one goal at a time.

Endurance sports are exploding. There’s a lot of opportunity for beginner and amateur athletes to find success. 

There are a million things the pros are doing that you could be, too. These are a few of my favorite and most straightforward to implement.

If you want to learn more, I recommend reading Matt Fitzgerald and Ben Rosario’s book Run Like a Pro, Even if You’re Slow. It has many useful strategies, especially for runners.
