You can't make this up:
Fatima Yvelain is a regional-level distance runner in France. I suspect you had not heard of her until now but she enters history with one of the best ever excuses for a positive doping test.

Following a positive test for EPO after a half-marathon, she claimed heavy rainfall on the day of race had caused water to stream over hidden medical waste somewhere near the course. As she ran, the EPO-laced rainwater splashed onto her shorts, thus contaminating her urine when she later provided a sample at the doping control.

Needless athletics website VO2.fr reports the French Athletics Federation didn’t believe a word. She is banned for two years.

Update: this is no hoax story. You can read the official sanction from the French Athletics Federation here.
