Swimmer Joanne Jackson took 400m freestyle silver ahead of Olympic champion Rebecca Adlington at the World Championships. The 22-year-old briefly held the 400m world record earlier in 2009 and leads our dozen to keep an eye on three years from London 2012

Flyweight Khalid Yafai was a surprise qualifier for Beijing, where he lost to the eventual silver medallist. That was his last defeat though and he won the European Union title in June. His younger brother Gamal may make it a family double in London
Jason Kenny had a fantastic Olympics in Beijing, winning team sprint gold, but he was beaten in the individual sprint by Sir Chris Hoy. However, expect the 21-year-old to be in the mix in the London Velodrome
