Running Strong After 40: Managing the Hormonal Shift

They say you don't stop running because you get old; you get old because you stop running. But for the masters athlete over 40, the rules of the game change. The training program that worked in your 20s can lead to injury and burnout in your 40s and 50s.

The Science of Ageing and Endurance

As we age, our internal chemistry shifts. For men, a gradual decline in testosterone can lead to slower muscle recovery and changes in body composition. For women, perimenopause and menopause bring significant changes in oestrogen that affect bone density and how the body uses carbohydrates for fuel.

Why Data Is the Fountain of Youth

To keep chasing personal bests into your 50s, you need to be more intentional. Monitoring your bloodwork allows you to:

1. Track cardiovascular health: Even if you look fit, the athlete's paradox means runners can still have high cholesterol. A lipid profile is worth knowing.
2. Keep an eye on kidney and liver function: Useful for those who regularly use anti-inflammatories to manage aches and pains.
3. Understand your hormones: Knowing your hormonal baseline helps you adjust your strength training and protein intake to maintain muscle mass.

Your Best Years Can Still Be Ahead

Plenty of runners in their 50s train strong every day. The difference is often in the data. By knowing your numbers, you can train with the wisdom of age and the energy of youth.
