Norfolk accountants are on course to raise �150,000 for good causes as part of an anniversary challenge.

The project, known as the LB150 Challenge, was set up in 2008 to mark the 150th anniversary of Lovewell Blake whose founding at Great Yarmouth predated official recognition of accountancy as a profession.

Total funds raised to date stand at �127,000 with 63 local charities and community groups having received grants of up to �2,000 through Norfolk Community Foundation. Ongoing and new activities are planned to reach the target by the autumn, including a sponsored London bridges walk.

'There's a lot of excitement through the firm going into the final year,' said Richard Keeler, manager at the firm's Great Yarmouth office and chairman of the fundraising panel.

'We felt we should mark reaching the target with a big event in the capital and we're planning a route for the walk that takes in the Olympic Stadium with London bridges.'

Other activities on the 2012 agenda include another attempt at the Three Peaks challenge – completed in 2008 but not within 24 hours – and a coast-to-coast cycle ride across northern England.

Recent beneficiaries include the Warren Association to provide facilities for those with learning difficulties at the Warren School in Lowestoft and Mettingham Village Hall.
