Adam Gemili and Dina Asher-Smith will go for gold on Saturday night in the 4x100m relay finals at the World Championships in London.
The 23-year-old Dartford star made his first appearance of the Championships on Saturday morning, running the second leg of the 4x100m and helping Great Britain & Northern Ireland to produce their second fastest time ever.
The quartet - completed by CJ Ujah, Danny Talbot and Nathaneel Mitchell-Blake - blazed round the London Stadium in 37.36secs, just three-hundredths outside the national record, to finish second behind the USA and book their place in the final at 9.50pm.
Gemili put the frustration of missing out on individual selection for the 200m after an injury-plagued season and said: "It's been a tough season but i'm really lucky and thankful to be a part of this team.
"Hopefully we can go out there in the final and challenge for the medals, which is what we're here for.
"We really want a medal but it is the 16 best teams in the world all after a medal so we know it will be tough but the crowd will help and this has helped put us in pole position.
"We are very lucky to have this crowd here in London."
The race will be the final one of Jamaican legend Usain Bolt's career and Gemili predicted: "It's going to be a great night to be a part of and one not to miss."
Gemili's Blackheath & Bromley AC teammate Dina Asher-Smith helped the women's 4x100m team into their final, despite running just 13 hours after finishing fourth in the 200m final.
Asher-Smith ran the third leg and helped ensure a time of 41.93secs which took them through in second, again behind the USA.
She claimed: "I'm always here for the team. If I'm needed in here, there are no hesitations. I was fine to run after the 200m so I was happy to run again with these girls."
Folkestone's Jack Green will hope to help the 4x400m relay team into Sunday night's final when the semi-finals get underway at 12.01pm.
Rabah Yousif, Dwayne Cowan combined to hand over to Green in third before the Maidstone born star closed the gap on second-placed Trinidad & Tobago.
Martyn Rooney took the baton for the final leg and though he was overhauled by Belgium in the final straight, the time of 3.00.10 was a season's best and took them into the final as a fastest loser.
Green said: "We knew that we had the toughest semi-final but this is the World Champs, we have to run against these people and we want to do it in the final so we're not going to complain about that.
"For me it's just an honour to be back in the team and running with athletes of this standard so I'm very lucky to be back."
He added: "It was solid but I don’t think it was anything to write home about. It was quite hard to go into a World Championships in what may as well have been the final.
"I am pleased that I was able to help the team out. I am pleased to be in the squad."
USA were the fastest qualifiers in 2.59.23 - the fastest time in the world this year - with Trinidad & Tobago in second, 0.12 behind, with Belgium in third.
The final is at 9.15pm on Sunday.
