Get ready to OSCAR MIKE! Head to Castle Island in South Boston on Sunday, June 28, 2026 at 10am for a 5-mile ruck that welcomes dogs and families—happening rain or shine. Oscar Mike Ruckers, a 501(c)(3) nonprofit, organizes this fitness-focused event to raise funds honoring fallen heroes and supporting their families, bringing together veterans, first responders, and community members to carry the weight of those we've lost and keep their memory alive.
