The Tour has changed a lot since the days when Desgrange was called an "Assassin", but it still remains the ultimate endurance event in mainstream sport. Merely getting to the finish is highly regarded, finishing last even has it's own accolade (Christmas teaser - who has the lowest ever placed finish - the lanterne rouge of the lanterne rouges ?). Such an event is obviously going to put your body under huge stress - some would say that more should be done to keep the rider in good health - intravenous recovery options should be encouraged, not banned - whereas the prevailing view is that it is a test of how the body deteriorates over 3 weeks.
As fans we don't don't want to see riders crashing over cliffs, or have 19 year-olds with blood like treacle dying in their sleep, but at the same time we don't want to see the sport emasculated either. And what elite sports people don't take a few risks with their long term health - hell, this is a climbing site, a sport which has always exalted those who push what is humanly possible to the very limits. And eulogised those who took one risk too many.
Getting to the top in any sport takes both talent and dedication - if Froome chooses to, and is able to stay off the carbs then that isn't morally suspect - it's a factor in what has got him to the top. (And the difference between him and those of us who ride for cake and/or cheesy chip butties). (as another aside - listen to Graham Obree talking to Richard Moore on the Cycling podcast - Obree reckons that the only difference between them was mental).
Now you could argue that riders should have a minimum BMI, or a BMI passport. You could even say there ought to be more testing on their mental stability. But in the absence of rules you will also get people who will push things to the limits and beyond - this is the nature of competition

Are they banned ? Are they harmful. If it simply a matter of cost then it becomes a cost/benefit question. Some people will spend £10 grand on a bike for a sportive.....
> Big money professional sport where winner takes all and make all the £ leads people to bend the rules.
Cheating occurs in sport at all levels. It's human nature. At least at the professional level there is a degree of independent oversight. Which brings me back to the beginning - the only reason we are having this debate is that one nation has been caught cheating on a massive scale and wants to undermine the credibility of the independent bodies that has sought to sanction them.
