Welcome to the Island!

Thompson Island is located just one mile from downtown in the Boston Harbor. With 204 beautiful acres encompassing storybook meadows, pristine salt marshes, and rolling hills. For more than 200 years, Thompson Island has been serving Boston kids.

All money raised through the 4k Trail Run supports the amazing work that’s happening on Thompson Island with kids from Boston Public Schools. Each year, thousands of middle school students come to Thompson Island for free, hands-on learning and team building, not to mention life changing time spent in nature.

Run for Boston's Youth

Make your run count! As one of 2,000 runners, you can make a difference to a Boston child by setting up your own personal fundraising page and asking your friends, colleagues, and family to support Thompson Island. We are launching a new and improved fundraising software in 2017. Check back soon to get started!
