The Cardinal Cup is a fall 5K run and 1-mile walk held at the School of the Cathedral, 111 Amberly Way in Baltimore. It is hosted by the School of the Cathedral of Mary Our Queen, with Mother Seton Academy invited as the beneficiary and community partner. The race features a timed 5K for runners and a shorter walk for those who want the day without the full distance.
The event supports Mother Seton Academy: net proceeds and all sponsorship donations go directly to the school. A past edition had over 500 participants, indicating it is more than a small school fundraiser. Awards are presented to the top three overall male and female 5K finishers, while the 1-mile option is open to younger children, families, walkers, and supporters focused on the cause rather than a race result.
