Every athlete approaches their sport differently at that starting line. It's one I went through for Canada for 20 years.
That starts in practice. You practise for many years and you simulate those circumstances, but on the day anything can happen, whether it's a factor such as the weather or nerves or what have you. You really prepare yourself in practice for those kinds of situations.
I remember one of the games in Korea in 1988 and being in the stadium with 80,000 people. It feels as if humming is going on around you, but you're so focused on your performance you don't think about that. You're focused because you're prepared, and you know you had a good team to help you get there, just like what we're doing for our athletes as we're bringing them toward London. You're trying to manage those natural distractions around you, with everyone pulling at you in so many different directions. When you're on the day you try to relax, to remember what your coach told you, what you have to do at each point in your performance, and then you just let it happen, and it does.
I think for a lot of these athletes who are going to be competing less than 50 days from now.... Again, everyone goes through it in a different way, but that whole notion of focus and relaxation and having rehearsed your performance hundreds and thousands of times I think is a quality most of us go through.
