Chris Froome crossed the line arm-in-arm with his Team Sky team-mates as he joined the elite club of three-time Tour de France winners on Sunday.
Despite crashing on a treacherous descent on stage 19 and borrowing team-mate Geraint Thomas' bike to ride the final 12km to the finish, Froome managed to extend his overall lead and then defend it on the final stormy day in the Alps, setting up the processional ride in to Paris.
Froome now leads the race by 4 minutes and 5 seconds and he and his team were revelling in the victory as the Stage 21 began on Sunday afternoon.
It was therefore up to the breakaway to produce a spark on an uneventful final day of possible hostilities as Izaguirre won the stage after a daring descent to the finish having crested the final climb, the Col de Joux Plane, alongside 2014 champion Vincenzo Nibali and Colombian Jarlinson Pantano, victor of the 15th stage last Sunday.
Nairo Quintana and Alberto Contador have already been confirmed as taking part, so Froome will face stiff competition for victory should he go.
Coming into the 2016 Tour de France, Great Britain's Chris Froome already had two Tour de France victories to his credit, the most recent coming just a year ago. "Kellan, I dedicate this victory to you", Froome said, also thanking his teammates and coaches.
For British team Sky, it was a fourth Tour win in five years - an incredible achievement for a team created in 2010, and for a country tha had never had a Tour champion before Bradley Wiggins in 2012. "It would be my dream to keep coming back to the Tour for the next five to six years if I can and give it my best shot".
Chris Froome paid tribute to the victims of the tragedy in Nice after winning a third Tour de France on Sunday.
There was one more British stage victor, as Steve Cummings produced a trademark success on stage seven into Lac de Payolle.
Finally there was a groundbreaking performance from Adam Yates, who will also head to Rio, as he became the first British rider to win the white jersey for the best young rider.
Only two riders - Jacques Anquetil in 1963 and Bernard Hinault in 1978 - have won the Tour and Vuelta in the same year.
Of course, it was not all fun and games - there was still a stage to be won - and Rui Costa (Lampre-Merida), Brice Feillu (Fortuneo-Vital Concept) and Daniel Teklehaimanot (Dimension Data) were among those getting their sponsors' names in the breakaway one final time.
The Team Sky rider said yesterday he is likely to take to the start of the fourth edition of the Olympic legacy event. He wore the leader's yellow jersey for 13 of the 21 stages.
Froome has crashed twice, made a daring attack at breakneck speed on a rapid decent, tamed the crosswinds and most memorably found himself running to the finish line on one stage after his bike was broken in a collision with a motorcycle.
Tour director Christian Prudhomme said watching Team Sky was "like watching Paris St Germain, they are so powerful, they always win the championship".
