Growing up in Cirencester, Gloucestershire, Trinder, 32, played most all sports, but began to focus all his energy on rugby at the age of 15. Post high school, Trinder attended Hartpury College studying Sports Science and to pursue professional rugby. He joined and played regularly for Moseley RFC in National League D1 from 2007-2009. Meanwhile, 2008 quickly became a turning point in Trinder’s career.
Trinder made his Premiership debut in March 2008 against the Sale Sharks, coming in for Leon Lloyd after injury. He also represented England on the U18s squad making eight appearances between 2008/09 and competing in the Six Nations U20 competition.
The following season with Gloucester, Trinder filled in for long-time Gloucester Mike Tindall making four starts. He again earned a spot with England, this time on the U20 squad for the Six Nations and making it to the World Cup Championship Final.
The 2009/10 campaign ended early for Trinder with an injury, but after earning an extended contract with Gloucester, he went on for a standout subsequent season. Scoring 13 tries in 23 appearances, the 2010/11 season was one for the books. This also marked his selection for England Saxons aiding in the side’s Churchill Cup win.
Trinder has made three England 1st appearances: two against the Barbarians (2011, 2014) and the other in New Zealand in 2014 against the Canterbury Crusaders. During the summer of 2014, he was also a part of the England Summer tour to New Zealand.
He continued his time with Gloucester Rugby through the 2015 campaign before suffering an ACL tear in 2016. Trinder battled back for the 2016/17 season making 12 appearances. In 2017/18 Trinder came back in top form having several high performing matches. He was awarded Man of the Match and two Try of the Weeks moments before the season’s end.
Awarded the honor from the loyal Gloucester fans, Trinder celebrated his Testimonial Year in 2019/20. With his time at Kingsholm Stadium coming to a close, Trinder closed out his Gloucester time in April 2021 after making a grand total 172 appearances for the club scoring 46 tries.
Trinder then made the move to France competing for RC Vannes, the Brittnay-based club in the Pro D2 competition, during the summer of 2021. Returning to the UK, Trinder was named Player-Coach of RFU Championship’s Ampthill RFC.
