What the LANDIS do we know?

OK, so I have sucessfully improved my blog by putting an image on it, Awesome, as they say here in Canada.
This is me, the very amateur athlete in PAIN!
Steve Cram the British and Olympic Medal winner pointed out that all athletes suffer, the good ones are just goinng a lot faster!
So pick a marathon, anywhere in the world, its full of septagenarians, cancer survivors, amputees as well as those dressed as wedding cakes or subway trains.
They all hurt.
People do it for fun ,to save face after drunken arguments about how flat the course really is, and increasingly for charity( big small ,and often intensley personal).
NONE of them do it for money or personnel prestige.
There are countless fine professional athletes in every sport the world over. They are competitors/ entertainers/proud to compete for their club town city or country.
Then there are the OTHERS, those who choose to take drugs in order to improve their chances, and therfore money and prestige.
Which brings me to my point( I may well go on about this problem for weeks).
Floyd Landis is currently embroiled in a drug accusation after winning the worlds greatest cycle race. He is accused of having eleven times more testosterone in his system than the normal value. The tour de france has been plagued by drug problems for years, and many of us sports fans would like to think that it was all largely in the murky past, the next few weeks will tell.
As a child I had no specific sporting ( or other) heroes. As an adult I have followed the Tour, every olympics, the Philedelphia eagles, etc, I am now officially disillusioned, but know there are hard working professionals out there tonight, training, eating egg whites ,drinking huge amounts of water and going to bed early , and they will do this every day until London 2012 when they will compete for the love of it, for Canada(or one of the other 168 or so nations).
I wonder how you tell them from the others???
