Pulpstar said:Doping clearly does go on in racing - Al Zarooni is obviously clear evidence of that. In addition different substances are legal in different juristictions.
As well as the fact you can use substances like bute on domestic horses but not racing stock.
Sir Henry though ? Doubt it but hey ho you never know.
One thing about the heart attack, horses heart rates go from ~ 30 at rest to ~ 240 at full exertion. Thats a HUGE range ( > Human athletes - 30 bpm - 200 tops maybe) and their hearts are obviously larger than human hearts so I'd think their risk of a heart attack are probably far higher than a human after a race. Not really evidence of doping.
Didnt say it was, just asking was it suspicious.
