Not only would he make more money at the NYC Half but the half marathon is more beneficial for him. It will give him a good idea of what kind of shape he is in as his goals are sub 27 and a fast Chicago marathon this year. World XC is a great race but has much less to do with his goals than a half marathon. Cross country is just not as much of a focus for Ritz as track or the roads. Regardless of money I think running a half marathon is better for Ritz.
