For the first time in more than a decade, runners will once again have the chance to race a half marathon in Worcester. Set in the spring and timed with prime race season, The Mass Half offers a unique opportunity to train, race, and celebrate in the Heart of the Commonwealth, whether you’re pursuing a personal best, preparing for a full marathon, or simply looking for a great reason to run.
But the experience extends well beyond the course. With thousands of runners expected to take part, The Mass Half will bring new energy to Worcester and Central Massachusetts, creating opportunities for local businesses, nonprofits, corporations, volunteers, and community partners to be part of one of the region’s biggest new annual events.
As United Way of Central Massachusetts’ signature annual fundraiser, powered by M&T Bank, The Mass Half also puts purpose behind every mile. Proceeds will support UWCM and nonprofit organizations across the region, helping advance the work that makes Central Massachusetts a stronger, healthier, and more resilient place to live.
The Mass Half is a race for the region; and an invitation for everyone to be part of what comes next.
