Woodburn partnered with Phillip Dutton to finish 2nd at the 2010 Kentucky Rolex Three-Day Event, the year William Fox-Pitt (GBR) and Cool Mountain claimed the title. It was a great contest from the dressage test onward. Phillip and Woodburn improved from eighth after dressage to fourth after cross-country to second after their second double-clear jumping round,  but they couldn’t catch the winners who also jumped faultlessly. The top two finished on their dressage scores, separated by 4.9 penalty points. Woodburn and Phillip won the Pentacle Cup as the highest placed Americans, but there is only ever one Rolex winner. Woodburn and Phillip also competed on the USA three-day team which finished fourth at the 2010 Alltech FEI World Equestrian Games.
