We all know it's hard getting tickets for the Olympics but it turns out the athletes have been having trouble too!
400m hurdler Dai Greene was told he's only allowed two tickets for his family and friends to come and watch, because a lot of people in the UK want tickets.
So Dai asked his fans to help him find some London 2012 tickets.
Fan Matt de Monte had never met Dai, but helped him anyway. He looked all over the internet and finally found some for £1500.
Dai called him the "man who saved my Olympics" when he met him to pay him back.
Dai isn't the only athlete asking for help.
Olympic rowing champion Zac Purchase was helped by fans who have found him 14 tickets!
