Marathon Season is Here!

As marathon season sweeps across Europe, cities are bracing for the flood of runners ready to turn months of training into triumphant 42.2 km journeys! From the iconic Paris and Vienna marathons to the streets of London and Manchester, thousands of participants are eager to conquer this mighty challenge—whether to beat personal records or simply to join the exhilarating atmosphere.

So, What Happens to Your Body When You Run a Marathon?

Running a marathon is more than just a test of endurance; it transforms your body in fascinating ways. Here are seven surprising effects you might experience during and after tackling those 26.2 miles.

1. You May Actually Shrink!

Believe it or not, studies reveal that marathon runners can lose up to half an inch in height during the race! This isn’t a cause for alarm; it’s mainly due to spinal compression and fluid loss between vertebrae.

2. Beware of Dehydration!

Post-race scales may shock you—many runners find they’ve shed as much as 5 kg of water weight. With frequent hydration stations along the route, it’s crucial to drink up; staying hydrated helps stave off dizziness and nausea while promoting muscle recovery.

3. Calorie Burn Galore!

The calorie count from a marathon can skyrocket to 3,500 or more, depending on your size and fitness level. That’s why carb-loading the night before is a common ritual. Your body mainly burns fats and fast-acting carbohydrates during the race, which is why many runners rely on energy gels for a mid-race boost.

4. Post-Race Appetite May Vanish!

Remember craving nachos at Kilometer 25? You might find your appetite makes a swift exit post-marathon. This is due to the diversion of blood flow toward your heart and muscles, suppressing hunger hormones like ghrelin.

5. Say Goodbye to Sleep!

After the exertion of a marathon, sleep may elude you. The adrenaline high from crossing the finish line coupled with elevated cortisol levels can leave you wide awake when all you want is to crash.

6. Expect Some Battle Scars!

Prepare for a few battle wounds: chafing, bleeding nipples, and possibly some lost toenails. Yes, running isn’t always pretty, but it’s a badge of honor for many!

7. Meet the 'Marathon Blues'

In the days following your big run, you may feel a bit down. It’s quite common to experience a low mood after the adrenaline rush fades. The months of training can lead to feelings of emptiness once the marathon is over.

With these insights, you're not only ready to cross the finish line but also to understand the profound impact a marathon can have on your body and mind. Whether you’re running for glory or simply for the love of it, prepare for a transformative journey!
