World Championship gold and silver medallists Christine Ohuruogu and Nicola Sanders have a few days to prepare themselves for their next 400 metres clash with a dominant Sanya Richards.
The 22-year-old American's latest success in yesterday's Golden League meeting in Berlin saw her again hand out a thrashing to her rivals as she stormed to victory in 49.27 seconds.
It was a race Richards was desperate to win, success assuring her of sharing the GL one million US dollars (£490,000) jackpot with Russian pole vaulter Yelena Isinbayeva.
The 2005 world silver medallist, after failing to make the USA team for Japan where she would have been favourite to lift the 400m title, has beaten both Britons and Jamaica's Novlene Williams on three occasions since post-Osaka.
Just as she did in Zurich 10 days ago and Brussels on Friday Richards posted yet another world-leading mark, finishing well clear of Ohuruogu and Sanders who clocked 50.40 and 50.60.
Now the British pair are determined to pick up their form for the IAAF World Athletics Final, a money-spinning end to the season in Stuttgart next weekend.
Ohuruogu, along with other world champions, has been given a wildcard as the IAAF want as many as the Osaka winners as possible in the Daimler-Benz stadion.
Sanders, after finishing second in Brussels on Friday and third in Germany's Olympic stadium, qualified by right to chase the 30,000 US dollars (£15,000) first prize.
Neither needs reminding Richards will be aiming to add to her kitty.
Apart from the 500,000 US dollars (£249,000) jackpot prize, her other successes have seen her earnings creeping towards the million mark.
The two British runners will hope a little more time at home will help them recapture the sub-50 seconds form they displayed in Japan.
Sanders admitted of her latest race: "At 200m I had nothing in my legs and I was struggling. Maybe it was the wind or that I was running my second race in three days. It's been like a mini-championships."
Ohuruogu, who missed the Brussels meeting to have a little more rest, confessed she was still not fully recovered.
"There's nothing very much different," said the world champion, who has fulfilled a massive racing programme since returning from her one-year ban after missing three out-of-competition drugs tests seven weeks ago.
But Ohuruogu insisted she is not the only one who is not hitting top form with nearly every other competitor who competed in Osaka also suffering from the effects of the heat and humidity.
She insisted: "I've taken inspiration from it. This is what everyone else has had to do as well and some have been away from home for a much longer time."
Marlon Devonish thought he had won over 100m and was almost celebrating when Jaysuma Saidy Ndure, out of sight, nipped in for a 0.01-second win in 10.15sec.
Ricky Fifton made it a good day for British sprinting, finishing third when lowering his personal best by 0.03 to 10.17.
Mark Lewis-Francis was never in contention, the former world junior champion coming last in 10.45.
Montell Douglas was eighth in her 100m race in 11.45 as the USA's world bronze medallist Carmelita Jeter won in 11.15.
