In a scintillating weekend's work at the England under-20 championships in Bedford, he not only grabbed the national title from under the noses of athletes far senior to him, but clocked an incredible 10.47 seconds, which leaves him as third fastest ever Brit, and second on this year's global lists for under-18's.
The latter is most relevant as his agenda takes him to Singapore in August for the World Youth Olympics, an under-18 competition.
"I think I might have cheesed a few people off," said David after the 100m on Saturday (19th), "because I'm friends with alot of the guys in the event, but nobody contacted me at all for ages afterwards. I think they were a bit shocked that an under-17 beat them, but we're all fine now."
Bolarinwa had caught the eye of the crowd right from the off, as he stormed to victory in the heats in a wind-aided 10.62 - the fastest he had ever run over the distance thus far. Then in the semi-final he clocked 10.43, but again the wind speed was over the legal limit.
When the clock stopped in the final everyone held their breath as the wind speed was communicated to the announcer's box.
"I must admit I was a bit awe-struck when we found out the wind speed was legal," said coach John Powell, "because this puts a copletely new dimension on David's career from here on. He will be seen as the new kid on the block, and the fun will soon become pressure as expectations rise, but he has a stable head on his shoulders and I am confident he will handle it."
Bolarinwa had not finished though as, barely 24 hours later, he was in action again in the 200 metres, making it six races in a 24-hour period, a challenge for the most senior of athletes.
The heats saw him speed round in a fastest ever 21.36, but again the wind speed was just over the permitted limit, but in the semi-final it dropped, and his 21.17 saw him fire into fifth place on the all-time lists for his age in the UK.
The final saw his first technical slip of the weekend as he didn't quite hit the bend hard enough, and he entered the straight with it all to do. His eventual third place in 21.21s, another wind-legal mark, earned him bronze in an age-group three years his senior, and wide acclaim as the athlete of the championships.
"David had an outstanding weekend and I'm immensely proud of him," said John Powell,"because not only did he run fast, he exeited his events really well in the main, and he is learning all the time. He's a great talent, but there is still much work to do, both before Singapore, and in the longer term before we start thinking about senior athletics."
Bolarinwa next races in the British Athletics League for his club, Cambridge Harriers, on Saturday July 3rd, after which he will be defending his English Schools 100 metres title, in Birmingham, on July 9/10th.
Trackspeed1 had one other athlete in action at Bedford on Sunday in Femi Owolade, and he too travelled back down the M1 with a smile from ear to ear.
The 22 year-old Blackheath and Bromley athlete sped through the heats of the under-23 200 metres in a lifetime's fastest 21.44 seconds in first, and progressed through the semi-finals with 21.53, although only as a fastest loser to the final.
In the final, he was drawn outside in lane eight making a solo run a real challenge, but he came off the bend well in touch with the leaders, and held on for a bronze medal he dare not have even dreamed about beforehand.
"I can't believe it," he said afterwards, "getting a PB was one thing, but winning a medal is beyond my wildest dreams, I am really happy."
Finally, the news was at last getting better for UK number three over 100 metres, James Ellington, whose tragic hamstring tear in Geneva earlier this month saw his European Championship dreams evaporate.
The 24-year-old Belgrave Harrier began rehabilitation work in the hydrotherapy pool on Sunday, and now must battle to prove his fitness before final selection for the Commonwealth Games. That is likely to be mid-August at the latest.
Femi Owolade is all smiles with his 200m Bronze at Bedford.
