This set her up for a series of wins at one-day and stage races including the Tour de l’Aude – one of the hardest and most prestigious in women’s cycling, never before won by a British rider. She won both time trial and road race British national titles, and topped the season with victory at the UCI Time Trial World Championships in Geelong, Australia.
In 2011 the Cervélo Test Team was taken over to become Team Garmin Cérvelo. Emma won the Trofeo Alfredo Binda World Cup – again in a solo breakaway. She then suffered a broken collarbone but returned later in the season to win the time trial stage of Bira-Emakumeen in Spain, a mountain stage of the prestigious Giro Donne (the women's Giro d'Italia) and the overall classification at the Tour de l’Ardèche. Her bronze medal in the UCI Time Trial World Championships in Copenhagen was impressive in demonstrating that she was also competitive on flat, technical courses: becoming a more versatile cyclist and expanding her already respected profile as a pure climber.
The Garmin Cervélo women’s team was discontinued in 2012 by the men's team management, and Emma raced for the Dutch team AA Drink-Leontien. She again finished 2nd in the general classification of the Giro Donne. At the 2012 London Olympics she finished 6th in the time trial and rode in support of Elizabeth Armitstead’s silver medal in the road race. She successfully defended her title at the Tour de l'Ardèche, including 2 stage wins. At the end of the cycling season, Emma ran her first marathon in Luzern, in a time of 2:55:36.
2013 saw Emma concentrate her efforts on completing her doctoral thesis. She raced with the small, non-professional Bigla Cycling Team whilst also returning to triathlon and running. She showed aptitude at long-distance multi-sport events, winning the inaugural Swissman Xtreme Triathlon and finishing 6th in the prestigious Jungfrau Marathon. She won the Lausanne marathon in a time of 2:44:29. On the bike, she won the inaugural Tour du Languedoc-Roussillon and two stages of the Tour de Feminin Czech stage race.
In 2014, Emma returned to professional cycling with Lotto-Belisol Ladies' Team. She regained her title at the British national time trial championship, following this with the mountains classification and three stage wins at the Giro Rosa (the renamed Giro Donne). She continued to combine triathlon with cycling, with podium finishes at Challenge Philippines and Rapperswil 70.3.
In order to concentrate on multi-sport events, Emma retired from professional cycling on 3rd August 2014 on a high, displaying her trademark grit and determination, achieving silver medals in both the road race and time trial at the Commonwealth Games in Glasgow. Just one month later, on 6th September, she won the Zofingen Powerman long-course duathlon world championship - breaking the course record by 16 minutes.
From 2015 Emma has been supported by sponsorship from the Norwegian Geotechnical Institute (NGI). That year, she successfully transferred to triathlon and won Challenge Philippines, the Alpe d'Huez long-distance triathlon, Embrunman, and defended her world champion title at Powerman Zofingen. At the start of 2016 she won Powerman Malaysia, came second at Rapperswil 70.3 behind Daniela Ryf, and then put multi-sport on hold to race with the Great Britain Cycling Team in an attempt to make selection for the Rio Olympics. In September 2016 she again successfully defended her world champion title in long-course duathlon at Powerman Zofingen, achieving an unprecedented three consecutive wins.
In 2017 Emma won the Ventouxman Triathlon and the European long-distance duathlon championship, as well as defending her titles at Powerman Zofingen and Taiwan KOM. She also returned to competetive running with a win a the infamously tough Inferno Halfmarathon (2100m of altitude gain).
