Running comes down to, in my opinion, bettering the self. Which translates for me, into PERSONAL BESTS. Everytime you set a personal best, you've achieved a new level of fitness that you previously were uncapable of. Gold medals of course have there merit, but think of it like this, you win the 2012 mile in 4:20, you are the gold medalist. Quite honestly, there are a number of factors that could have led to you being the "best" on that day. A world record however, means that YOU ARE the best, regardless of the situation because nobody else in the world could replicate the performance.
I think the whole idea of gold medals, and "olympic years" certainly does bring about competition in the sport, which is absolutely necessary for the PUBLIC. But, again in running, this is a very selfish sport, and one in which doing things previously thought "impossible" for the self, leads to satisfaction and the idea of building character.
Put it to you this way, everyone, or atleast a competitive athlete has a shot theoretically to win a gold medal given the ABSOLUTE best/luckiest circumstances whereas the world record comes down to ABSOLUTE ability, NOT tactics as is the case with most championship races.
I think running for the "gold" kills more dreams then does reveal them. If you run to run YOUR best, wouldn't that ultimately be a better ways anyhow to win the gold? Rather then leaving it for the final 200m to decide?
Again, every 4 years a NEW OLYMPIC champion is crowned, the same cannot be said for a world record, it is only "imagined" when it will be broken, if ever.
