It's a great race, have fun! I got the train back last year, I think I was stood up but it wasn't crowded like a commuter train over here, there was plenty of space to move. I'm sure I could have got a seat if I'd tried.
And you two have no problems when you run? I would normally go three or four times and have constant trouble when I run - is it just this simple? Am I just doomed by my usual regularity/lack of meat in my diet?
