American Margaux Isaksen (Fayetteville, Ark.), a fourth-place finisher at the London Olympic Games, highlights a field of 150 athletes, including seven 2012 Olympians, as the 47th UIPM Junior World Championships take place Sept. 3-9 in Drzonkow, Poland.
Isaksen, 21, whose fourth-place finish in London was the highest finish for a junior athlete, will be looking to take home the women's title in her last year as a junior. She will be joined on the team by her younger sister, Isabella Isaksen (Fayetteville, Ark.), as well as Samantha Achterberg (Littleton, Colo) and Alison English (Ventura, Calif.).
The U.S. men's team also boast a pair of siblings in Nathan and Lucas Schrimsher (Roswell, N.M.). They will be joined by Marshall Stymer (Philomath, Ore.) and Brendan Anderson (Colorado Springs, Colo.).
