He sustained a broken heel in the Robins' Elite League fixture against Belle Vue in July 2008. He recovered and returned for Swindon later in the season but broke his collarbone in another crash at Coventry and was unable to ride for the Robins in the Elite League play-offs.[6]
He was part of the Berwick Bandits team that won the Premier League Four-Team Championship, held on 15 July 2012, at the East of England Arena.[7] The same season he rode a few times for Swindon and helped them win the 2012 Elite League.[8]
In 2013, he rode for the King's Lynn Stars in the British Elite League.[9]
In May 2016, during a game against the team Sheffield Tigers, Aldén suffered a neck fracture in a crash.[10] After the crash he began to participate in triathlons.[11] In 2022 he qualified for the Ironman World Championship but did not participate.[12]
