World Taekwondo GP: Jade Jones & Bianca Walkden target gold
World number one Jones has already secured Britain a place in the -57kg division for the Rio Games, but Walkden - who is ranked third in the +67kg class - still has work to do in order to secure Britain in her division.
Walkden lost ground on her rivals after suffering a ruptured anterior cruciate ligament injury last year, but tells BBC Sport's Nick Hope that her comeback has astounded medical experts.
