once made me cry.

It was 1 August 1996 when he crossed the Olympic finishing line having set a new world record for the 200 metres in Atlanta.

It was either whoop with delight or cry in astonishment, and I'm not ashamed to admit his earth shattering achievement, setting a record which still stands today, elicited a salty eyed response.

I couldn't believe what I'd just seen and I felt privileged to have witnessed it. Those golden shoes, that upright stance, those short steps and his squatting by the trackside clock are all images that will live with me forever.

is now giving you a unique opportunity to talk with Johnson.

The only man to win both the 200m and 400m at the same Games will be with us on Wednesday, 13 August and if you have any questions for one of the greatest Olympians of all time, here's your chance.

You can use your webcam to speak to him directly or you can e-mail your questions to mygames@bbc.co.uk.

We'd also like to hear your memories of Michael Johnson's achievements.

Competing at Barcelona '92, Atlanta '96 and Sydney 2000, he's a four time gold medallist, which would have been five had his 4x400m relay team mate not been running under the influence of illegal drugs in Sydney.

Johnson is also the only man to have successfully defended a 400m Olympic title.

A nine-time World Champion and a multiple winner of various athletics and sports awards, he's now a very watchable, well-informed and engaging television pundit, often working for the 大象传媒 during the European athletics season and the Olympics.

We're lucky to have him; he is a legend.

So, what would you like to ask him?

It can be anything - from what he has for breakfast to whether he thinks drugs and doping are eventually going to ruin the credibility of athletics.

The former world 100 metres record holder believes drug cheats should be imprisoned, I wonder if Johnson agrees?

Wednesday's the day, Beijing's the place, and Johnson is the man!

For me, it's going to be a huge privilege just to shake his hand, I just hope I don't cry!
