In February 2008, Sotherton competed in a three-event triathlon, at the Indoor Grand Prix, in Birmingham, against a field including Carolina Klüft. Sotherton started with a below-par performance in the long jump, allowing Klüft to take the lead. Sotherton then won the 60 m hurdles in a personal best of 8.17 seconds. Despite running a personal best (and the fastest time by a Briton that season) of 52.47 seconds in the 400m, Sotherton took second behind Klüft, who won by 18 points.
