Finally in 2003, Thames achieved an emphatic win in the Wyfold Challenge Cup which was repeated in 2006. This success was further compounded in 2015 when Thames won the Thames Challenge Cup for club eights, the first time the club had done so since 1934. This was followed in 2016 by a win in the Visitors' Challenge Cup for intermediate coxless fours. In 2017, there was an unprecedented achievement: two Thames crews reached the final of the Thames Challenge Cup, with Thames A beating Thames B by 5 lengths. The following year, Thames retained the Thames Challenge Cup, and won the Britannia Challenge Cup for the first time in its history, setting a course record in the process.
