Dani King, Joanna Rowsell and Laura Trott combined to win Olympic team pursuit gold two years ago - on Friday they'll be rivals in the 3000m individual pursuit at the Commonwealth Games in Glasgow.
Olympic champion Jason Kenny admitted he was lacklustre in men's sprint qualifying but claimed he'd bounce back and he'll be joined by Matthew Crampton and Philip Hindes. And Andy Tennant and Steven Burke, silver medallists in the team pursuit, go in their individual event.
British champion Chris Walker Hebborn will go for gold in the 100m backstroke after setting a new Games record in Thursday's heats - but his biggest rival could be team-mate and defending champion Liam Tancock.
In addition Fran Halsall starts her 50m freestyle campaign as she seeks to upgrade her silver from four years ago while Siobhan Marie O'Connor, the fastest qualifier, goes in the 100m butterfly, where Welsh swimmer Jemma Lowe will be among her rivals.
At the Barry Buddon Shooting Centre, rising star Amber Hill, just 16 and the youngest ever winner of a World Cup event, goes in the women's skeet.
