Tweddle is not the only celebrity to have been injured while taking part.
Melinda Messenger was forced to pull out in the first series after sustaining concussion while practising for the bobsleigh.
Meanwhile, in the second series, Ola Jordan suffered a “serious” injury to her leg and hips after she fell over at an indoor ski slope. She has since said her leg may “never be the same again”.
The show last aired in 2017, with Made in Chelsea star Spencer Matthews pipping Olympic gymnast Louis Smith to win the series.
