High flying Gloucester have made moves to solidify their status as one of the leading clubs in the Aviva Premiership, re-signing four players.
“It’s been a great start to the season, and it was an easy decision for me to remain at the club,” said former England and British & Irish Lions centre Twelvetrees, 29, who has made over 100 appearances for Gloucester.
“It’s been frustrating for me to miss the start of the season, and see the boys impressing, and I’m hugely excited to get out on the pitch and add to the team.
“The way the boys are trying to play under Johan [Ackermann] is great to see and suits me down to a tee. I’m delighted to continue my time here and play in front of the Gloucester fans.”
Fellow centre Trinder, 28, is in his tenth season at the club, playing over 120 games.
Meanwhile Ludlow, 23, made his debut in 2013 and recently made his 50th appearance.
