Lennox Lewis and Wladimir Klitschko not only became World Heavyweight Champions, they also claimed Olympic gold medals.
Lewis won the super-heavyweight title in Seoul in 1988 - four years after he was eliminated in the quarter finals during the Los Angeles Games - while Klitschko topped the medal rostrum in the same weight division in Atlanta '96.
And with the boxing bouts at London 2012 getting underway on Saturday, the duo shared some memories of their Olympic campaigns with Ringside reporter Ed Robinson...
LENNOX LEWIS
"I didn't allow the pressure to get to me; I just wanted to get in there and fight every day and perform at my best. I lost in 1984 to Tyrell Biggs in the quarter-finals but I was still in high school at the time and I thought I was the best boxer and wanted to go back and win the gold.
"The whole world will be watching London 2012 and so many countries are preparing their athletes and there will be a lot of pressure on them. Mentally you have to prepare yourself for the next opponent or even all three. You have to think: 'First I have to deal with the guy from Poland, then the guy from India and then the guy from Russia'.
"I would have loved to box in London, but [British super-heavyweight] Anthony Joshua will be. I've spoken with him and he is a great guy, very positive; he is looking forward to it and he is going to do well. It's up to him now and he has to put everything all together as this is the most important tournament he is ever going to be in."
WLADIMIR KLITSCHKO
"I never thought I could make it until I saw Muhammad Ali lighting the flame at the opening ceremony in Atlanta. It then clicked in my mind and I thought: 'I can achieve this'. I was fighting on the first day of the Olympics and I was fighting on the last day of the Olympics so for two weeks I had to stay focussed. That was pretty difficult because it is a long time.
"You're not really there as you're going from fight to fight but then you've got the gold medal you've been working for for many years. I then went back to Ukraine and had the reception from my friends and all the excitement from my family. I didn't realise until a couple of weeks later [that I was Olympic champion]."
