Fundraise to Increase Your Impact!
Fundraise with your team to win some great incentives and make an even bigger impact on our island!
Encourage and incentivize your employees to participate in the fundraising initiative by pledging a matching challenge. The corporate match will be added to the team’s overall fundraising and go toward the team fundraising incentives. Runners can make a direct impact in the life of a Boston Public School student by conducting their own fundraising campaign. It costs $2,300 for one BPS student to participate in our multi-year Connections program. By committing to raise $2,300 you will ensure a student can visit the island 12 times during their middle school career.
