Olympic medallist Samantha Murray visited Millfield last week when the Street school hosted the Pentathlon GB South Christmas youth residential camp.
Murray, who won modern pentathlon silver at London 2012, attended the same camp in 2003 and made a guest appearance last Wednesday to put aspiring pentathletes through their paces.
She passed on the expert tips and advice that also helped her win a World Championship bronze medal and rise to third in the world rankings this year, before giving a talk about her Olympic success.
Murray and her fellow Team GB pentathletes were also at Millfield during the summer, when they used the school's equestrian centre to undertake extra showjumping training ahead of the Games.
Fellow London stars Katie Dawkins and Katie Skelton were also at the Street school earlier in the week when Millfield hosted its first-ever residential synchronised swimming camp.
After helping Team GB to a sixth-placed finish in the women's team event in the London Aquatic Centre, the pair were the perfect choice to lead the camp.
