For the next few weeks I'm going to be in London - I'm super excited, not just because

I'm a big fan of long distance running, but also because I'll be making videos about the

physics of sports, collaborating with Derek of Veritasium, and so forth.

There are so many awesome things at the Olympics and in London – so where should I start?

Go ahead and leave questions or suggestions in the comments below, and thanks in advance.

I'll see you in England.

Or is it the United Kingdom? or Great Britain? or

the British Empire? or–
