Backyard Day

  • Backyard Day Start My Journey

Whether you're concerned about clean water in your community, asthma-triggering smog, or unsustainable development, we want to support you in making a difference in your own backyard. 

Which is why we’re celebrating the third annual Backyard Day on September 14 — a day dedicated to the place you call home.

Registration goes up August 15th, so sign up today!

Now - Aug 15 - $30

Your backyard doesn't have to be the space outside your back door. Whether the local trails, the beach you grew up visiting, or the park your kids love goofing around in — we're celebrating all of the outdoor spaces you consider yours.

Join us by doing a virtual 5K or 10K — or any favorite outdoor activity of any distance — in a place you love. Walk, run, roll, hike, swim, kayak, skip, cycle: the important thing is that you get outdoors and connect with nature. And if you want to get your friends and family to come along? Even better. After all, getting outdoors is not just fun — it's good for us and can inspire a commitment for protecting these special places and our planet.

Wherever you feel at home in the outdoors — like the local trails or the family's favorite pond — or the spot you want to share with others!

When you sign up and complete your $30 registration donation, you'll be joining friends and families around the country in getting outdoors to protect the places we love and call home. Plus, you'll receive the Team Sierra Backyard Day keychain and downloadable race-day bib.

Start a Backyard Day Campaign

In addition to your registration donation, you can create a fundraising page to share with family and friends! You can raise awareness for the serious threats facing our planet and our future, and they can support you on your 5k/10k/outdoor activity as well as your desire to do something for our planet.

The money you raise benefits the Sierra Club and is critical in protecting wildlife and wild places, tackling this climate crisis, and ensuring a healthy, livable planet we can all depend on.
