Great Britain celebrated double relay joy as the World Championships came to a close, with both the men and women's teams securing 4x400 metres relay bronze.
A string of promising displays in Beijing brought with it four golds and fourth place in the medal table, but they entered the final day of competition a medal short of UK Sport's minimum target of six.
There was no need for concern, though, as both relay teams produced solid, medal-winning performances in the 4x400m.
Having seen Christine Ohuruogu, Anyika Onuora, Eilidh Child and Seren Bundy-Davies impressively secure bronze, the reigning European men's champions followed suit at the Bird's Nest.
Rabah Yousif, Delano Williams and Jarryd Dunn got Great Britain off to a fine start, with team captain Martyn Rooney anchoring them home in style just ahead of Jamaica in two minutes 58.51 seconds - a great way to celebrate this week's birth of his first child.
The relay team mimicked rocking a baby when introduced to the crowd before the race in celebration to the new addition.
Rooney missed the birth as he was in Beijing, but the sacrifice paid off as he darted to the line to beat Jamaica by four thousandths of a second.
"My first child, a special week for me," he told the BBC. "I couldn't go home without bringing something back to my wife.
"I'm proud of what she's done and hopefully she's proud of me." USA won the race - a sixth successive men's 4x400m gold - in a world-leading 2:57.82, with Trinidad and Tobago second despite a national record time.
The Americans had been expected to do the double, but Jamaica pipped the favourites to glory in the women's event and Britain secured bronze with a season's best 3:23.62.
"We decided to change the order slightly," Ohuruogu said. "Put me on first leg to try and get the team into contention and hopefully use my speed to put us in the mix.
"I was a bit worried after Thursday because I knew I'd gone off a bit too hard.
"I didn't want to make the same mistake again but they did so brilliantly. I'm really happy for our new additions."
Only two other British athletes were involved on the final evening of competition, with Charlie Grice's time of 3:36.21 seeing him finish ninth in the men's 1,500m final and Steph Twell ending 12th in the 5,000m.
