Waterdeep: The Plowing and Running

From the introduction: The city of Waterdeep is well known for its citizens’ fondness for celebration. Barely a tenday passes without at least one festival taking place within the City of Splendors. Near mid-spring, during the month of Mirtul, one such occasion is celebrated by friendly competition between the different wards of the city. While the Plowing and Running holiday originated to celebrate the plowing of fields and running of livestock in rural areas, the metropolis of Waterdeep holds a series of foot, horse, and chariot races throughout the multi-day event.
