A double-helix spiral running track winds its way around a 45-story office tower located a few blocks from Times Square, providing circulation for a vertical park. An apparel company occupies 50% of the building; sponsored athletes test out new products on the track and utilize the courts. The other 50% of the office space is rented out to assorted businesses; all the tenants may use the athletic facilities located throughout the building. A retail outlet for the apparel company is located on the ground floor.
