"We started from nothing in 2007 and we've improved out of sight since then. We are simply not prepared to give up now."
The ride has also received the backing of Deputy Prime Minister Nick Clegg, who is the MP for Sheffield Hallam.
"It gives me great pride as a local MP to see that the ladies GB volleyball team are prepared to cycle to London to raise as much money as possible so that they can fund their training," he said.
"This really is an inspirational act and I am sure that the public will be backing the team and offering their encouragement to them on their journey."
The planned route will take the team through Nottingham, Loughborough, Leicester, Stratford, Oxford, Reading, Hampton Court, Richmond Park, Westminster and Trafalgar Square, before coming to an end at Earls Court on Tuesday night.
Along the way, they will take part in demonstration volleyball events, offer the public rides on a seven-seater-bike, provide an inflatable volleyball court and meet local people to spread the word of their venture.
Volleyball was one of eight sports to have had London 2012 funding slashed in January because of a £50m budget shortfall.
