Caroline was the top Under 25 Eventing Rider in North America and the top young rider in the United States for the past four years, an unprecedented achievement. She earned individual and team gold medalist at the 2013 Adequate®/FEI North American Youth Championships and made her CCI5* debut with Spring Easy at the 2017 Kentucky Three-Day Event. That summer, she traveled to Great Britain with Pebbly Maximus and The Apprentice. She competed in the FEI Eventing Nations Cup™ at Houghton Hall and placed in the top-10 with both horses in the CCI4*-L U25 at Bramham. With Islandwood Captain Jack, Martin placed second in the CCI4*-L divisions at both Jersey Fresh and Rebecca Farm in 2018 and was awarded the Leading Lady Rider title from the United States Eventing Association.
The pair traveled overseas in 2019 and completed the CCIO4*-S at Aachen and placed third in the CCI4*-L at Millstreet.
Caroline is short listed for the upcoming Olympic Games.
