And now, as the summer rolls towards an end, he can look back in the safe knowledge that it has been nine months of brilliant success.
But as the Great Britain sprinter and Europe's quickest 100m runner this year winds down towards winter, his mind has new focusses.
Ahead in 2014 are the World Indoor Championships in Sopot, the European Athletics Championships in Zurich and the Commonwealth Games in Glasgow.
But Dasaolu is thinking beyond even those. He is already in the cycle towards the next Olympic Games in Rio de Janeiro in 2016 by which time he hopes he has a new landmark to his name - the European 100m record.
The time of 9.86 was set by Portugal's Francis Obikwelu when he won silver at the Olympics in Athens in 2004.
Dasaolu, 25, put his mark on the event with 9.91 at the British trials this summer to soar to the top of the European rankings and stay there; now he would the European record itself.
He said: 'In terms of my career, that is one of my long term goals - to break that record in the next two to three years leading up to Rio. It is half a metre and it is a realistic target.'
His summer will end on Saturday in Gateshead when he runs the 100m at the Great North CityGames and he knows there is more improvement ahead in years to come.
Dasaolu, who won silver in the 60m at the European Athletics Indoor Championships in Göteborg in March, has been with coach Steve Fudge for only 18 months and is only just starting to reap the benefits.
'I am yet to fulfil my entire potential under him,' said Dasaolu. 'It normally takes two to three years to run the best with your coach.
'It has been a brilliant season. It kicked off by winning my first medal for my country. Then I ran the 9.91 and I finished it off by making the final in Moscow.'
Even though he was eighth in 10.21 as Jamaica's Usain Bolt won in 9.77, it was a big breakthrough to be in the final.
Dasaolo added: 'I have had loads of positives to take forward to the next few seasons.
'I need to let my body rest and recover from the season. I am going to take maybe a month or six weeks off and then start at the back end of October, working on trying to get my race perfect.
'It is not perfect yet and there are things we need to work on to improve in terms of my training load, and how much I am training. I am not running probably as far, or as much in volume, as other people.'
His training has been concentrating a great deal on his starts. Now it is for the finish.
He said: 'I focused on getting my start mechanics right rather than the back of my race. But running longer distances in training, such as 250s and 200s, makes you stronger in the latter part.'
And all in good time, the even quicker times will arrive and that European record will be ever closer.
