More than 100 women took over the streets of San Francisco to show the new Womens Ultraboost running shoe as they completed a series of running experiences over the two-day event. Each event was designed to be greater than the last through a combination of distance, unique challenges or inspiring locations – and all allowing people to ‘run test’ the new UltraBOOST X.

During the event, the dynamic group of women conquered San Francisco’s most challenging urban environments – from storming up one of the city’s steepest streets, completing a gruelling track session at Kezar stadium or a HIIT treadmill work-out to a live DJ set by Hannah Bronfman to pounding the iconic Golden Gate Bridge. The series of once-in-a-lifetime running challenges ensured each guest overcame her own personal barriers.
