PRAGUE — Diminutive in stature but determined as ever, Jessica Springsteen counted the steps between the vertical obstacles so she could calculate the number of strides for the 11-year-old bay mare RMF Zecilie.

Springsteen, 26, who is 5-foot-6, was careful not to overlook any detail as she crafted a plan to leap 16 fences with her explosive yet agile Holsteiner breed horse. Together, they would try to navigate a serpentine course of 480 meters, or about 525 yards, in a little more than a minute.

The only daughter of Bruce Springsteen and Patti Scialfa, who also have two sons, she has proved her talents as a professional show jumper, ascending the ranks of international competition.

After two seasons with the Shanghai Swans, she recently concluded her first season riding for the Miami Celtics, a new entry in the three-year-old Global Champions League, a tour of show jumping competitions. The Celtics consist of four Irishmen and her, and competed on a 17-event, four-continent circuit. With wins this year in Mexico City and Rome, and second-place finishes in Cannes and Doha, the Celtics quickly became a force.
