Who won the TdF with only one kidney?
Answer: Greg LeMond

Dave Reid and Sean Co posted the correct answer.
Here is a pic of his shot gun pellets. When I am breathing really hard in the mountains and about to get chipped I think of the LeMonster and try to remind myself that my lungs are actually running at full capacity unlike his.
