Running in your 40s (and beyond!) doesn’t have to be difficult

After more than Two decades of training Olympic, professional, collegiate and adult athletes, there’s one phrase I hear over and over again from runners in their 40s: Why does this suddenly seem so much harder?

Most assume they are losing stamina. That their aero engine is fading. This era has finally caught up. You probably feel the same way, but I can tell you that’s rarely the whole story.

I work with many athletes who still want to perform at a high level, and I can say that things change in your 40s. But what changes — and what makes running seem more difficult — may not be what you think. Fortunately, There are solutions To ease the physical changes you’re going through so that running becomes fun again.

What changes in your 40s?

Let’s start with physiology. Even in trained adults, VO2 max gradually declines with age – approximately 5-10% per decade if untrained. But with sustained training, this decline is much less, and into your 40s, aerobic capacity remains highly trainable.

But bigger shifts tend to happen elsewhere. Among both men and women, I constantly see:

• Gradual loss of fast-twitch muscle fibres
• Slight decrease in muscle mass without resistance training
• Decreased tendon stiffness (“spring” is less elastic)
• Longer recovery windows between strenuous efforts
• High cumulative life stress (work, family, sleep disturbance).

Most runners don’t lose their lungs in their 40s. They lose strength, strength and elasticity of tissues. This changes how running feels.

Additional spells for men

• Gradual decrease in testosterone and growth hormone
• Slight reduction in muscle maintenance if strength work is inconsistent
• Slow recovery from high-intensity sessions.

Additional transformations for women

• Perimenopause may begin During this decade hormonal fluctuations can affect energy and sleep
• Changes in collagen production may affect tendon elasticity
• Greater variation in recovery from week to week.

Performance may seem less predictable. Some weeks you feel strong. Others feel superficial. This does not mean that physical fitness disappears, but rather that physiology becomes more dynamic.

So, for most runners in their 40s (and in some cases 50s and beyond) the aerobic drive is still going strong. But strength and flexibility – such as “popping” off the ground, lightness of step, and the ability to lunge without thinking – diminish. When force production decreases, the pace becomes more difficult, even at the same heart rate. This is the transformation. Not endurance. power.

The psychological transformation that no one talks about

There is also something less measurable but quite real. In your 20s, fatigue seems normal. In your 40s, fatigue seems like a warning. In your 20s, you recover quickly. In your 40s, you’ve probably suffered at least one injury.

By this decade, many runners had lost a little confidence in their bodies. The effort feels heavier not only physically, but mentally as well. This shift alone can change how you feel each round.

What keeps you going strong in your 40s?

Strength, power, tendon flexibility, ability to recover and to withstand stress become the new bottlenecks. when You train accordinglylifts the weight. The runners I coach who are still feeling strong this decade focus on three things:

1. Single leg strength

Running is controlled by landing with one leg over and over again. Split squats, steps, and hip stability exercises protect the knees and hips and improve step control. Aim for 3-4 sets. 4-12 reps.

Bulgarian squat

1. Stand a few feet in front of the bench/chair and place one foot behind you on it.
2. Lower your back knee toward the floor. Keep your chest high and active.
3. Push through your front heel to return to standing.
4. Complete one set on one leg, then switch.

Stand forward lunge

1. One step forward.
2. Lower the knees until the back knee is close to the floor.
3. Push with the front foot to return to standing.
4. Complete one set on one leg, then switch.

steps

1. Place one foot on a step or sturdy bench.
2. Push off that foot to raise your body up the step.
3. Pull back with control.
4. Alternate legs that you climb up with.

Single leg squat

1. Stand on one leg with the other extended forward.
2. Bend your standing knee and squat down while maintaining balance.
3. Push your foot back up.
4. This is an advanced move — use a wall for balance and don’t try to go too deep when you start.

2. Posterior chain strength

The glutes and hamstrings drive the push. Deadlifts, hip hinges, and controlled power work maintain force production and economy of operation. Aim for 3-4 sets. 4-10 reps.

Deadlift

1. Stand with your feet hip-width apart and secure at the hips to pick up the weight. You can use a barbell, two dumbbells, or a kettlebell.
2. Keep your back straight and chest up as you drive through your heels to stand.
3. Lower the weight back to the middle of the leg by pushing the hips back.

Leg curls

1. Lie face down on the machine with the pillow behind your ankles.
2. Curl your heels toward your glutes.
3. Slowly lower your legs down.

Hip Thrust/Glute Bridge

1. Lie on your back with your knees bent and feet flat on the floor.
2. Push through your heels and lift your hips up.
3. Squeeze your glutes at the top, then lower them back down.

3. Calf and Achilles ability

Your lower leg is your spring. Slow, controlled calf raises and progressive plyometrics maintain a flexible back and reduce the risk of injury. Go for 3-4 sets. 10-20 reps.

Leg raises (straight and bent knee)

1. Stand with your feet hip-width apart, knees straight
2. Raise your heels as high as possible.
3. Lower your heels back down slowly.
4. Complete one set, then repeat but with your knees bent.

Pogo jumping

1. Stand straight on the balls of your feet.
2. Make quick, small hops using mostly your ankles, landing softly each time with a slight bend in the knees.

Box jump

1. Stand facing a sturdy box or platform.
2. Jump up, using the momentum from your arms to assist.
3. Land softly, stand upright, and then step back down.

You can also incorporate other plyometric exercises From this guide.

When do you do the exercises?

Plyometric and explosive work should be performed at the beginning of the session, after the warm-up, when the body is fresh. Throughout the week, runners should do one session to emphasize single-leg strength and one to emphasize posterior chain strength.
