EDITOR’S NOTE: Usain needs to meet Kenenisa half way, such as 1500 meters. Be fair!!

Thessaloniki, Greece (DPA/CNN) – Usain Bolt concluded what has been a phenomenal season with another breathtaking display over his favourite 200 meters distance at the World Athletics Final in Thessalonika.

Bolt said tiredness towards the end of the race, which has prompted him to call his memorable year to an immediate halt, slowed him, although he still roared to another fantastic time of 19.68 seconds at the Greek venue.

Bolt, 23, won a world title treble last month in Berlin and bettered his world records in the 100m (9.58 seconds) and 200m (19.19) there.

On Friday, he participated in a street event for local children and allowed the five-year-old boy finish first. “It was really fun with the kids,” said Bolt.

While Bolt can’t wait for his post-season break, he did look ahead when he suggested a race over 600m or longer against Ethiopia’s track star Kenenisa Bekele in 2010.

“To me running a 600 would be really interesting. It’s been a while since I have done it but I think it would be fun. So if my coach decides to let me do it, then I would definitely do it,” said Bolt.

“It would be really interesting. I think a lot of people would definitely want to see that.”

Bekele is the world and Olympic champion and world record holder in the 5,000m and 10,000m, Bolt has the same merits in the sprints.

Bolt and Bekele are two top names among 28 world champions from Berlin to compete in Thessaloniki Saturday and Sunday. Each win is worth 30,000 dollars and a world record 100,000 dollars.

Russian Yelena Isinbayeva, who flopped at the worlds when she cleared no heights, could further raise the pole vault record bar to 5.07m.
