Thank you to GotSneakers?, Athletic Greens, and Allbirds for sponsoring this episode.

GotSneakers? makes it socially and financially rewarding to contribute to a circular economy with their FREE sneaker recycling program.

As runners, we go through a lot of shoes, but many of them that we consider "done" still have life for others. In the U.S. alone, at least 200 million pairs of shoes and sneakers wind up in landfills each year, where they can take 30-40 years to decompose. Meanwhile, more than 600 million people worldwide don't even own a pair of shoes. When you join the GotSneakers? community, you'll be making a global impact AND you'll earn money for the shoes that you send them. Go here to get started!

Athletic Greens has created a movement around simplifying our health routine. AG1 is an easy way to get 75 vitamins, minerals, and whole food source ingredients. It promotes gut health with prebiotics, probiotics, and naturally occurring enzymes; supports your immune system with Vitamin C, zinc, healing mushrooms, and more; provides magnesium to boost energy; and it's packed with superfoods, adaptogens, and antioxidants to help recovery. It's simple to make and it tastes good!

Just one scoop in a glass of water in the morning will ensure that even if your diet is less than ideal the rest of the day, you've gotten the nutrients you need. Go here to subscribe and you'll get five free travel packs of AG1, and a free one year's supply of vitamin D3+K2 with your subscription!

Allbirds looks at everything through a sustainability lens; it's at the core of who they are as a company and the products they create. Their performance running shoe, the Tree Flyer, is lightweight, super springy, and wildly comfortable, and they're Tina's go-to running shoes. The Tree Dasher is not only a running shoe, it's perfect for daily wear. You might also want to check out the Plant Pacers, made from plant leather.
