[3] Post-retirement he initially worked as an athlete intern at Goldman Sachs in London,[4] then joined The Service Course, in which he is an investor, as COO and now CEO, in early 2020.

[citation needed] Gerrans took up cycling after injuring his knee and speaking with his neighbour, former Yellow Jersey holder Phil Anderson whom he credits with introducing him to the sport.

[citation needed] Gerrans underwent surgery at a hospital in Nice following a heavy fall in the GP d'Ouverture la Marseillaise in February, 2006.

Barely surviving attacks from the other strong climbers in the breakaway, in which the fourth rider was dropped from the group, he eventually sprinted away in the last few dozen metres, without a response from the two remaining contenders.

[2] In January 2012, Gerrans became national road race champion for the first time, out-sprinting Lampre–ISD's Matthew Lloyd and Team Sky's Richie Porte for victory.

[24][25] On 17 March 2012, Gerrans won Milan–San Remo in a three-man sprint finish, beating RadioShack–Nissan's Fabian Cancellara and Liquigas–Cannondale's Vincenzo Nibali to the line in Sanremo.

His participation in the Volta a Catalunya yielded more success, winning the sixth stage in a sprint finish; he did so by a bike length ahead of Gianni Meersman of Belgium.

After a lead-out from teammate Pieter Weening, Gerrans sprinted to his third stage victory of the year ahead of a fast-finishing Peter Velits of Omega Pharma–Quick-Step.

Orica–GreenEDGE also won the team time trial the following day, beating Omega Pharma–Quick-Step; as a result, Gerrans donned the race leader's yellow jersey, only the sixth Australian cyclist to do so.

Having failed to get the inside line on the left-hand curve, with his Omega-Pharma team out of the picture, Cavendish was pushing with his head and shoulders in a desperate attempt to move Australia's Simon Gerrans to the left.

Cavendish lost control of his front wheel and fell heavily on his right shoulder, with Gerrans, a stage winner and yellow jersey wearer last year, hitting the deck simultaneously.

[32] Those two wins announced very good form just ahead of the World Championships in Ponferrada, in which he came in second place after his select group failed to reach lone escapee Michał Kwiatkowski.

[36] In the Tour de France, Gerrans was involved in a massive, high-speed crash on stage 3 and he had to quit the race due to a broken wrist.

[43] In September 2017 it was announced that he would join the BMC Racing Team for 2018, with a role as a road captain and key domestique for Richie Porte and Greg Van Avermaet.

[46] In August 2018, he announced in an open letter published by the BMC Racing Team that he would retire from competition at the end of the season, stating that his "passion for the sport is not what it used to be", but indicating that he wanted to remain involved in cycling in some capacity after spending more time with his family.
