Irish comedian Stevo Timothy is attempting to complete a charity cycle on Saturday in aid of the Irish Wheelchair Association.
The Galway comic, who has incomplete paraplegia following a motorbike accident in 2015, uses a wheelchair and walks with the aid of crutches.
Mr Timothy, who is known for his Farmer Michael sketches, said training for the 5km cycle saw him get back on a bicycle for the first time in "six or seven years".
He has been documenting his training on social media, where he has a significant following, and has received shout-outs and messages of support from a number of celebrities, including professional footballers Seamus Coleman and Gary Lineker, former footballer Paul McGrath and actress, writer and comedian Dawn French.
Mr Timothy will undertake the cycle on a 400m track on Saturday, and so far he has raised over €40,000 through his GoFundMe page.
