Indurain's Lungs
Legend of Garry Nelson
He was. World champion at 21 when clean.It's easy to forget Lance was an incredible cyclist.
I don't think his drug taking has been traced back to his pre cancer days.
Although I may be wrong, as quite frankly I'll be happen to never see or hear of him again. (easier said than done with my sport of choice)
He was World Champion, and he won a couple of classics.
