People are going to get older and young guys are going to come in and race and get more competitive.
People are very open-minded about new things - as long as they're exactly like the old ones.
But it is nice to know that you have other races lined up, because sometimes you can get so focused on your next marathon that it can become kind of unhealthy in some ways. So it's nice to have something else to slap you in the face and say, all right, there is life after the Olympics.
