Two colleagues from a Norwich law firm will be undertaking a tough challenge when they attempt to cycle from London to Paris in just 24 hours for charity.

Paula Lawn and Aidan Tidnam, who work for Leathes Prior, will be cycling to the French capital as part of the London to Paris 24 event in June in aid of Scope, a charity that supports disabled people and their families.

They will be riding relay-style in teams of two. Miss Lawn will be cycling with her partner Richard Lee, while Mr Tidnam will be paired with another rider.

The ride itself is nearly 300 miles and split into nine stages of roughly 35 to 40 miles, giving participants the chance to swap with their team mate. Lorries will transport the bikes between stages and the resting team member will travel on a coach between stages.

Miss Lawn, 43, of Bramble Way, Wymondham, is an employment lawyer and an associate at Leathes Prior, based in The Close.

She said: 'I got into sports two years ago when I stopped smoking, and took to it like a duck to water. I've been taking part in triathlons and this year I wanted a really big challenge.

'Aidan mentioned this event, which satisfies my desire for a challenge, and it's for a really good cause. My aim will be to get Paris without being too tired to shop when I arrive!'

Mr Tidnam, 34, of Denmark Road, Norwich, is facilities manager at the firm. He said: 'I'm quite a keen cyclist, although I'm not a member of any clubs.

'I've cycled in the Pyrenees and I've done the Norwich 100, but this will be an even greater challenge. I'm hoping to use this as a stepping stone to do even bigger things for charity.'

Miss Lawn and Mr Tidnam need to raise a minimum of �1,000 each for the charity. They are being supported by Leathes Prior, and will soon be out on training rides, wearing kit bearing their employer's logo.

'If people see us out on the road, I hope they'll give us a toot!' said Miss Lawn.
