Arzhanov had win the last 27 races of 800m he did participate and didnt loose a single 800m competition since 2 years and half and that included the European Champs, top meetings, trials and so. Take a look to the specialized Track and Field press about Arzhanov in the years of 1970 and 1971..

They did put him as the world best 800m runner in 1970 and 1971. Besides you may remember that was the time of the cold war USSR-USA in politics. Do you remember the chess duel Spasky-Ficher? Do you remember the run to be the first one on the moon ? To say that Wottle was the favourite because he did the WR some months earlier that´s simplistic. How many WRs did come to 1972 Olympics to loose ? Do you remember Jim Ryan ? Ok he felt, but do you remember Emil Puttemans or Derek Clayton ? Finnaly how many favourites in the 800m and 1500m events you want that i name to you that they come to the Olympics as favourites and they loose ?
Wottle win was a spetacular one and quite unexpected one.
Do this exercise. Ask a young boy that didnt watch that video and didnt know who was the winner and do pauses in each 100m splits, and ask him who the hell he thinks that goes win? I bet with you that when lasts only 100m most of the young boys willnt say thats Wottle who will be the winner.
