I don't doubt that Indurain was a great athlete. I think he had a Vo2 max of about 88 and could put out a lot of power. But he weighed 78kg when he was slim.
I'm not sure of my numbers but apparently the drug ridden tours of the 1990's and the Armstrong era saw the winners putting out around 6.7-6.8 watts per kg. I've seen figures quoted for Indurain of 6.8 and 7.0 for Riis in 1996. Some estimates of this year's TDF suggest 6watts per kg. This I'm told is a lot more believable.
Do I think Indurain used EPO? For me, there's no doubt he did.
The point they all miss is that the USADA case is not just about doping it is about the whole conspiracy to evade detection
USADA:
"The USPS Team doping conspiracy was professionally designed to groom and pressure athletes to use dangerous drugs, to evade detection, to ensure its secrecy and ultimately gain an unfair competitive advantage through superior doping practices."
I posted in the LA thread with a list of USPS riders who have admitted doping but didn't ever test positive. The fact is that there is overwhelming evidence (not least the admissions of many USPS team members) to support the USPS conclusion and the fact that LA never tested positive (even if that is true) is neither here nor there.
Sad to see the likes of Miguel Indurain still trying to support LA when he won't even defend himself.
I think there needs to be a broad enquiry (as suggested by Travis Tygart and others) and then a very public and very aggresive anti-doping programme: I am sure Pat McQuaid is working on it as we speak.
