UK Athletics have promoted five athletes to the group that receives the top level of lottery funding in 2007.
Farah (L) and Lyne impressed at the European Championships
Mo Farah (5,000m), Becky Lyne (800m), Michael Rimmer (800m), Sam Ellis (800m) and Mara Yamauchi (marathon) are all on the world class podium funding list.
A total of 37 athletes are included, five down from 2006, but more can be added later on.
Sian Edwards (5,000m), who impressed at the World Junior Championships, is in the world-class development programme.
"We have taken care not to accelerate younger athletes to podium status before they are genuinely performing at that level," said UK Athletics performance director Dave Collins.
"The programme continues to ensure that the athletes being supported are those with the right processes and remain accountable.
"Therefore some have been funded on the basis that this support will be further reviewed in six months' time.
"There can be a temptation to fill every available space on a funding programme.
"However the choice of athletes affords us the opportunity for additions later on in the year, as well as a certain amount of flexibility."
