Thank you to all 2026 participants, sponsors, donors, and volunteers!

  • 2026 Race Recap

    We did it again! Through the generous support of more than 30 local business sponsors, 400 participants, and dozens of volunteers--we were able to raise $134,417.65 to support Cancer Connection, Inc., a nonprofit community cancer support center serving individuals and families in Western Massachusetts. This brings our 16-year fundraising total to more than $945,000!

  • The Course

    The WMass Mother’s Day Half Marathon course takes runners through the 413 towns of Whately and Hatfield, in the shadow of Mt. Sugarloaf and past some of the region’s most fertile and productive farmland along the banks of the Connecticut River.

    We are a USATF Certified Course (#MA11002JK).
