The cycling World champion is significantly less successful during the year when he wears the rainbow jersey than in the previous year, and many have said this is due to a curse.
Thomas Perneger at Geneva University Hospital, Switzerland, put his intellectual petal to the metal to find out if this curse is real and details his work in the Christmas issue of The BMJ.(1)
The "rainbow" jersey is worn by the current cycling World champion (it is white, with bands of blue, red, black, yellow and green across the chest) and many cyclists believe that the World champion will be afflicted with all manner of misery while wearing the jersey- injury, disease, family tragedy, doping investigations, even death - but especially a lack of wins.
