In 2006, Eppu Salminen of Finland challenged Ben Johnson to a 30 meter sprint.
Yes, that Ben Johnson. Mr 9.79 back in 1988.
In the video below on YouTube, Ben is 44 years old.
Remember, Ben split 3.80 for 30 meters back in 1988 (SEE: Usain Bolt 100m 10 meter Splits and Speed Endurance)
We don’t know the full timing system used for this “race”, but Ben does run a 4.40.
Not a bad attrition rate!
