5% faster in 44 years. It seems quite a small improvement in some ways but perhaps puts in perspective how tough it is to be in the top 8. Wells was in the amateur era and had a pb of 10.11 which is pretty impressive given that he was prob running in Dunlop green flash and never used starting blocks until the Olympics in 1980.Shows how times change, needed to run 10.16 to get out of round 1 at this Olympics.
