Chris Froome won the Tour de France in 2013, but this year, instead of flying from the UK to France like everybody else, he went 250 feet under the sea crossing the Channel Tunnel reaching 40 mph at some points.
Eurotunnel's service tunnel is one of the highest security sites in the UK and France and with the current threat level from international terrorism for the UK being assessed as substantial (level 3 out of 5), it's no wonder why Jaguar and Team Sky needed six months to organize this 55 minute long bike ride.
The Channel Tunnel is celebrating its 20th birthday this year and remains one of the biggest engineering achievements of the last century. And talking of engineering, Chris Froome's Pinarello Dogma F8 racing bike is not a bad kit either.
The reigning Tour de France champion had this to say about the experience:
Cycling under the sea was an incredible experience.Opportunities to become the first person in the world to achieve these kind of feats are extremely rare nowadays, especially as a pro-cyclist. To become the first person ever to cycle through the Eurotunnel was right up there with some of the most iconic rides I've ever done - this must have been one of very few 'world first' rides left!
