The significant thing about 2007 is that that was the year I posted my highest mileage and longest runs... I did virtually no short, fast stuff at all until the end of the year, but increased my speed across all distances.
Of course that doesn't prove anything... But with that being my experience you can see why I have that disconnect with short races. But maybe if I tried more training for and running short races I would change my mind!
If you don't want to train for shorter races don't do it.
Personally I think shorter distance races may help me. But that's just me.
