There have been some great sprinting rivalries over the years - Usain Bolt v Yohan Blake, Carl Lewis v Ben Johnson - and now you can add to the list Ilmari Koppinen v Emiel Pauwels.
Koppinen is 95 years old and 11 months younger than his Belgian rival, and the two sprint kings went head-to-head over 65 metres at the recent Veteran Games in San Sebastien, Spain.
The race turned out to be one for the ages as Koppinen used his blistering pace out of the blocks to take a huge lead on 94-year-old Pauwels.
However, 'The Belgian Bolt' soon got into his stride and a Usain-esque burst near the finish saw him take a superb victory from the jaws of defeat.
Koppinen also got a gold medal for his troubles as he was crowned over-95s European Champion for his performance with Pauwels getting the nod in the 90+ category.
It proved to be a memorable Games for Pauwels, who also walked away with golds in the 200m, the triple jump and the shot put in the 90+ class, although he was the only person to compete in each of those events.
