Pokemon HG

So, I am playing through HG and I just beat curelean city and now I am trying to go get suicune since that douche fellow is chasing it, but the problem is I go to the spot where I am supposed to go and they are not there.

Anyone know whats up?

go south west past lavender town and he will meat you again and say something about knowing where suicune is and then says he will race you there
