Three-time world champion's son Marlon was born in Monaco yesterday...

Peter Sagan and his wife Katarina have announced the birth of their first child, a boy named Marlon.

The Slovak cyclist, who last month became the first man in history to win the road world championship for the third year running, broke the news on Twitter.

He had used the same social media platform earlier this year to announce that the couple were expecting a baby.

The new addition to the Sagan family was born yesterday in Monaco, where Sagan is now based, the star-studded principality affording him a degree of anonymity that he cannot enjoy in his native country.

The past few weeks have been a happier time for Sagan than the first few months of 2017, with just one win in the Spring Classics campaign at Kuurne-Brussels-Kuurne and his disqualification from the Tour de France in July.

In September, he took his 100th professional win at the Grand Prix Cycliste de Quebec then followed that up with his third consecutive rainbow jersey as he outsprinted Alexander Kristoff, racing on home soil in Bergen, Norway.

Sagan chose to stay in Monaco to be with his wife as their child’s birth approached rather than attend the UCI World Gala in Guilin, China.

“I think you understand that family comes above all, so I want to be by the side of my wife,” he told the audience at the event, where Belgium’s Greg van Avermaet was crowned as UCI WorldTour champion for 2017. 

Born in Scotland, Simon moved to London aged seven and now lives in the Oxfordshire Cotswolds with his miniature schnauzer, Elodie. He fell in love with cycling one Saturday morning in 1994 while living in Italy when Milan-San Remo went past his front door. A daily cycle commuter in London back before riding to work started to boom, he's been news editor at road.cc since 2009. Handily for work, he speaks French and Italian. He doesn't get to ride his Colnago as often as he'd like, and freely admits he's much more adept at cooking than fettling with bikes.
