I don't think 'hobby' and 'athlete' are mutually exclusive. (not that I'm putting myself in the latter category, please note).
My mate Andrew rode an unofficial 306 miles on the 24. The husband of one of his colleagues then refused to believe her when she recounted that Andrew at work had ridden that far in the day - he thought she must have meant the combined distance for both of us. I think that if anyone can elicit that sort of disbelief - and 306 miles in 24 hours isn't too much different to a fast 400 - then they deserve to be called an athlete. Matt, I think you do yourself a disservice. Inside the bubble, we tend to measure achievements by a different standard to that used by most other people.
(By the way, hi. I think I saw you at the weekend but didn't get through the crowds to introduce myself.)
