Throughout his time as a professional rider he has, like most of his peers, suffered bumps, knocks and broken bones along the way.
The first injury the British born Irishman mentions is a freak crash that occurred in the 2014 Vuelta a España where someone in front of him stopped abruptly and he managed to crash uphill as a result.
Going over a barrier and slicing his leg, his riding wasn’t really affected but walking proved slightly more difficult. He was particularly aware of the injury when walking up to take the top step on the podium at the Tour of Lombardy later that season.
The 2014 Giro d’Italia was over just minutes after it started for Martin after he and several teammates went down on a slippery raod surface in the opening team time trial.
The 29-year-old notes that most of the crashes he’s got caught up in have been as a result of people going down in front of him.
He now hopes that his new team can shepherd him to safety a bit better and get him back to winning ways.
