Yorkshire's leading sporting sons and daughters will today help launch the county's own marathon, which is being established in memory of late charity fundraiser Jane Tomlinson CBE.
Cricket legend Dickie Bird, TV football pundit Chris Kamara and double Paralympic gold medallist Hannah Cockroft will help launch the event in York.
The Plusnet Yorkshire Marathon, which is expected to raise up to £500,000 for charities in its first year, will take place in the city on October 20.
The 26.2 mile race is being organised by Jane Tomlinson's For All Events, which was set up by the Tomlinson family as a legacy to late Wakefield-born fundraiser and campaigner.
Jane Tomlinson raised almost £2 million for charity in her lifetime by tackling a series of endurance challenges despite being diagnosed with terminal cancer. The former amateur athlete died in September 2007.
Kamara, who will help launch the marathon at Clifford's Tower in York today, said:
Cockroft, who is also supporting the event, said it would build on Yorkshire's incredible showing in the 2012 Olympics. She said:
Jane Tomlinson's For All Events already runs the successful Leeds, York, Hull and Pennine-Lancashire 10Ks and the sell-out Leeds Half Marathon.
Jane's widower Mike Tomlinson said he hoped the Plusnet Yorkshire Marathon would now become a major highlight of the UK's sporting calendar.
Runners will be able to raise funds for any cause of their choice or one of the event's partner charities - Martin House Children's Hospice, Macmillan Cancer Support, Yorkshire Cancer Research, Parkinson's UK, the Haven, Clic Sargent, Candlelighters, St Leonard's Hospice, Sue Ryder Care and the Jane Tomlinson Appeal.
