Gemili finished fifth in the 200m final at the World Athletics Championships in Moscow last night in a time of 20.08 seconds, only four hundredths of a second behind Curtis Mitchell who took bronze.
And while that was slightly down on his historic effort in the semi-final the night before, one must remember it was Gemili's first-ever global outdoor final.
On Friday night Gemili won his semi in a staggering time of 19.98s, only the second Briton to go under 20 seconds and the first European teenager to achieve the feat. The prize for winning his semi-final was a good lane draw in the final, lining up in lane five with the legendary Bolt on his inside in four.
Within a few strides the six-time Olympic gold medallist had caught the British teenager but to his credit Gemili kept calm and focused on his own race. His time of 20.08s meant his three runs in Moscow this week are the three fastest of his career so far.
Bolt's successful defence of his title came in a world-leading time of 19.66s, his compatriot Warren Weir giving him a fright in the home straight to take silver while American Mitchell was third. Jamaica's Nickel Ashmeade had to settle for fourth, just three hundredths of a second ahead of Gemili.
With his best years ahead of him, Gemili cannot wait to continue his progression.
"What an incredible experience that was for my first senior final, to be outside of Usain Bolt and just be in the top eight in the world and then finish fifth. I'm very proud and very grateful," he said. "I was introduced just after Bolt when the whole crowd erupted and I was thinking 'wow I hope one day that could be me'. It just puts a smile on my face so I can stay relaxed.
"I was very close to a medal, and I missed out on the 100m final at London 2012 by four hundredths of a second as well.
"Hopefully as I get older and a bit stronger that gap will come down and in a few years I will be up there getting medals. It's a lot of hard rounds and I have missed a lot of endurance work this season. I can't complain about fifth in the world.
"I'm walking away with a new PB and fifth in the world so it's two thumbs up from me.
"I'm only 19, I still have a lot of growing to do physically and mentally, so I hope in a few years I can be out there winning."
Bolt and Gemili were shown on the big screen clowning to the camera in the warm-up before the final and Gemili revealed the Jamaican had also found time to dispense some wisdom the youngster.
"I couldn't believe how relaxed the warm-up room was, everyone knows everyone from the season," Gemili added.
"Usain told me to go out in the final and just enjoy myself. He said that one day I would be old like him so to enjoy it while I've got the chance. When you hear him coming up on your inside during the race you have to be so focused to not lose concentration."
Bolt became the first man to claim three 200m world titles, making it look all easy.
And that is exactly how he described the race afterwards, despite posting a world-leading time: with the 4x100m still to come he appears to be holding something back to make it three golds in Russia.
"I am just really happy to get it done and I am really happy to win the 200m as well because it is my favourite event," Bolt said.
"I knew it wouldn't be a particularly fast time. I ran the corner pretty hard and came into the straight and started to feel tired.
"My coach says that if you start feeling tired then it doesn't make any sense if you start pushing your body because that is when you get injured.
"So I started to look around, decided I was going to win and decided to back off a little bit."
