MCW Westfield Ultra

The MCW Westfield Ultra is an annual endurance running event held at Tamaques Park in Westfield, New Jersey. Participants can choose from 3, 6, 9, 12, or 24-hour race durations, aiming to complete as many laps as possible on a 0.8-mile loop featuring both pavement and gravel surfaces. The race supports MissionCleanWater, a nonprofit dedicated to providing clean drinking water globally, with registration fees acting as donations.

The event offers aid stations, allows support crews and pacers, and includes special rules for 24-hour runners such as mandatory headlamps and reflective vests at night. Fundraising participants raising $500 receive race fee refunds and guaranteed future entries. Visit the organization's website for the most recent information.
