American professional track and field sprinter Christian Coleman had a phenomenal outing at the US Indoor Championships in Albuquerque on Sunday as he broke the 20-year-old world record set by track legend Maurice Greene.As you can see in the video further down the page, the 21-year-old clocked a time of 6.34 secs, surpassing the previous best by Greene which was 6.39 secs.Shortly after his win, Coleman told the IAAF website that, despite a ‘not-so-ideal’ start, nearing the midway point he actually felt quite comfortable.He said: “I was just trying to come out with the win. My start was decent. Every time, I feel like I’ve got a lot of work to do (coming out of the blocks)."When I transitioned, I stood up, and I felt as good as I’ve ever felt. For it to be the world record was pretty special.“I just love this sport. It’s so competitive, and either you’ve got it or you don’t on this day. I just love racing in the big races, when everybody’s watching. I just flourish in those moments. It’s not really in my personality, but when the lights are on, it just comes out.”Coleman thought he had broken the world record last month when he ran 6.37 at the Clemson University, only to be informed that the timing was not ratified by the IAAF due to lack of use of electronic starting blocks.

Of course, such an impressive performance prompted social media to erupt. However, one person's reaction to the display particularly stood out.

Twenty years after Maurice Greene set the record, the four-time Olympic medalist could only watch on as Coleman pinched the accolade but he still reacted by posting a classy tweet.

The 43-year-old wrote: “Congratulations to @__coleman new World Rec in 60m. I’m proud of you glad you did it. 6.34”

Coleman, the double silver medallist at the World Championships, is destined for more success in the years ahead as he now aims for more record breaking acts to outlast and outpace some of the elites in the sport in future events.
