BBC Radio Lancashire's Graham Liver is to cycle the nearly 500 miles from the Eiffel Tower to Blackpool Tower.
The breakfast presenter's doing the ride next month to raise money for Children in Need.
The 'tower to tower' ride will link up Paris' most famous landmark with Blackpool's – the design of which was famously inspired by its French cousin.
Graham is no stranger to long distance bike rides, having travelled from Leeds Castle in Kent to Leeds last year – at the time he did the mid-morning show on BBC Radio Leeds.
"In a funny way I am looking forward to it, but I know it will hurt," Graham tells us. "Everybody keeps giving me advice, mainly about how to cope with saddle sores, but I know the pain will be worth it and the people of Lancashire will dig deep and give us lots of money for Children in Need."
Graham will be setting off from Paris on Friday 1 October, hoping to reach Blackpool by Thursday 7 October and has set himself a fundraising target of £3,000. Listeners will be able to help him reach his goal by donating via his [link=http://www.justgiving.com/Graham-Liver0]JustGiving page[/link].
John Clayton, Managing Editor at BBC Radio Lancashire, said: "We always like to come up with new ways to raise money for BBC Children in Need – but this year's challenge is going to be one of the toughest yet. Graham has done a bit of cycling before, but I'm not entirely sure he knows what he's let himself in for – it's certainly going to be extremely tough and very hard work. We want the whole of Lancashire to get behind him for this very worthy cause."
Graham will continue to do his breakfast show during the challenge – stopping off at BBC studios he passes en route. He's due to leave Paris on 1 October and travelling via Rouen, Le Havre, Portsmouth, Swindon, Coventry, Stoke-on-Trent and Manchester before finishing in Blackpool on Thursday 7 October with a live OB on the Radio Lancashire afternoon show.
