In 2006 at
O-ringen the Elite runners got to rerun a course used for an Elite event in 1975. The 1975 race was a special "Clash of Champions" that was televised in Swedish TV.
In 1975 the winner was World Champion Bernt Frilén in 60.16
In 2006 the winner was Andrey Khramov of Russia in 60.59.
An interesting fact was that everyone knew well in advance that they would rerun this old course and had the opportunity to study the old maps. Slightly different approach which may have affected the results naturally.
The course was extremely fast in the open pine forest and made for some amazingly fast running. In 1975 the world record holder in 3000m steeplechase, Anders Gärderud, ran the first half in under 4:00/km but lost some time in the end.
