You call a meet in Australia in Febuary a big meet with world class competition? Give me a break! German runs against faster guys at NCAA's and USA's. And as far as Gregson going to world champs, the only experience he has gotten at these meets is how to get destroyed by much faster runners, like at world xc.
if you had any idea what you were talking about you would know that Ryan raced all over europe last summer in races that went significantly faster than any NCAA athlete is capable of running, at the World Champs in Berlin, and yes, got his ass handed to him.
And yes, it is exactly this experience which will allow him to go to London completely relaxed in that environment
