NOVEMBER 1, 2021 is the LAST day to donate!  Help us reach our goal!

Join us for the Great Avalonia Trail Trek, a week-long fundraiser to support Avalonia's efforts to conserve land, protect watersheds, and address the climate crisis!  From Saturday, October 16 to Sunday, October 24, 2021, you will have the opportunity to hike, run, kayak, or cycle* on Avalonia's preserves- all to benefit the Avalonia Land Conservancy!  

To participate, just register for the activity you would like to do - your registration fee goes to Avalonia and is tax-deductible. Once you are registered, you will receive a personal fundraising page that you can send out to friends and family for donations (again, all donations are tax-deductible!) Then get out on the trails from Saturday, October 16 through Sunday, October 24 to get some fresh air and a good workout!

We will have prizes for Top Vertical Challenge, Top Mileage Challenge, fastest time around our official Trail Trek 3.1 mile loop at  the Atkinson Preserve,and Top Fundraiser.
