How do I create a fundraising page?

You can create a fundraising page here.

What does a fundraising page look like?

Here's an example of a fundraising page.

I've never raised funds before, where do I start??

You can use our fundraising toolkit, or email team.sierra@sierraclub.org, and someone from our team will set-up a time to help you!

Where does the money go?

The money will support many of Sierra Club's initiatives like retiring coal plants, moving away from fossil fuels, and transitioning to clean energy, like solar and wind. Read more about the Sierra Club's mission.

Activity Challenge

Where do I do my 1.5 miles or 15 minutes?

This is a virtual challenge, so it's up to you! We suggest going outside (and bundling up if where you live is cold!) or doing these in your home. Please follow CDC safety guidelines for COVID-19.

How do I track my miles or workouts?

You can use your own tracking device, like Strava, a Fitbit, or any app of your choosing, and report back on our community Facebook group. You can keep track the old fashioned way with pen and paper. Or if you set-up a fundraising page, you'll have access to our endurance tracker. This tracker has the ability to track minutes, so if you are opting to do mileage, make sure you keep track of your time! The endurance tracker can sync up with Strava. We're excited to see the total number of minutes at the end of the Challenge! 

What are the terms and conditions?
To sign up for this event, you must be at least 18 years of age. Everyone that participates must agree to our Acknowledgement, Assumptions of Risks, Release & Indemnity, and Binding Arbitration Agreement and Volunteer Fundraiser Agreement.
