Classical music and running

It's my surprise that so many runners are lovers of classical music. I find many fans of clssical music at a runners/hikers fans site (go2nature.net)
So do I.

I began to love classical music after I love running in 2/2004's HK Marathon.
Rock and roll was my favourite beforehands.
I wonder is there any link between running and classical music?

I agree that after I listen to the playing of Johannes Brahms by Jacqueline Du Pre, I was deeply moved by her excellent skill and emotional playing

I also enjoy listening to the "L'Enfance du Christ" by Berlioz on Radio 4 of RTHK right now

What a wonderful opera!
