For the first time in history, just over 50% of all races are run by women.  

While women are leading in the number of participants, research on women in sport is still stubbornly behind the guys'. We know that women and men perform differently, carry and use fat differently, as well as react to pain differently. Typically, men are bigger, stronger, and faster, until you get to the ultra distance, where women can actually break the tape first.

On today's Run to the Top, Dr Megan Roche, 5-time national trail champion and Stanford researcher explores the science behind the biological differences between men and women in endurance running.  

And this is not just a show for the women runners. Guys, you'll want to listen up as well if you want to know why the women are getting better and better.

This week's show brought to you by:

Magnesium Breakthrough from Bioptimizers. 

Supplementing with magnesium before you go to bed has been shown in scientific studies to…

• Increase in muscle oxygenation during high intensity exercise
• Reduce inflammation 
• Significantly improve sleep quality
• Improve aerobic exercise capacity when training.

When you're looking for a magnesium supplement, make sure you take one that is organic and has all 7 unique forms of magnesium. 

My recommendation is Magnesium Breakthrough from Bioptimizers because it's made with the highest quality, organic magnesium and contains all 7 critical forms. Most other magnesium supplements are synthetic and only contain one or two forms of magnesium, which is simply not enough.

For an exclusive offer go to magbreakthrough.com/runtothetop and use code run10 to save 10% when you try Magnesium Breakthrough. Plus, they offer a full refund up to one year after your purchase, no questions asked.

Ask yourself - do you get enough green veggies each day?

I'll admit, I don't. It's tough to fit all of those greens in with an active and busy lifestyle.

But getting in your fruits + veggies is SO crucial as a distance runner for recovery, digestion, and optimal performance.

That's where Athletic Greens is a gamechanger. One scoop has 75 bioavailable vitamins, minerals, and whole food-sourced ingredients including a multivitamin, multimineral, probiotic, green superfood blend, and more.

That means fewer stomach issues, more focus and energy throughout the day (because the workday matters just as much as the morning run), and overall ... just feeling healthier.

Look, if you're struggling to get those fruits + veggies in - or if you keep buying them but they always go bad in the fridge - Athletic Greens will make getting those micronutrients simple and delicious.
