The Rainbow Jersey is the crowning achievement of any cyclist’s career, proof that they are the very best in the world. GCN stats guru Cillian Kelly heads to Belgium in a lighthearted jaunt to chat to ex pros, pros and journalists about how the Rainbow Jersey undoubtedly brings with it greatness, but also the pressure to live up to the win. In 'Legend of the Rainbow Jersey’, Cillian uses his statistical nouse as he crunches the numbers and speaks with a selection of former world champions including Michal Kwiatkowski, Rui Costa, Philippe Gilbert and Johan Museeuw about riders wins and losses after winning this famous jersey. Finally, Cillian watches from the roadside as current world champions Remco Evenepoel and Annemiek van Vleuten take on the Ardennes hills in Liege-Bastogne-Liege. Will they crown their season as world champions by winning in rainbows? Or will the jersey weigh heavy on their shoulders?
