Lodders set the pace for the Rotary Club.
All are taking part in the Rotary Shakespeare Half Marathon on April 25 organised by the Rotary Club of Strat-t ford-upon-Avon.
Steven Baker, a commercial property partner, and Sonia Kang, a solicitor in the business group, are aiming to boost the funds and awareness of the Warwickshire Association for the Blind, Lodders' nominated Charity of the Year.
The charity aims to improve the lives of all blind and partially sighted people living in Warwickshire.
"It does a wonderful job," said Mr Baker. "It offers great support and kindness."
Mr Baker is a middle distance off road specialist and a member of Stratford Athletics Club and Miss Kang is also a keen runner.
Mike Wakeling, who has taken part in the London Marathon, and his wife Jane are raising money for their nephew Steven Ward, a Newcastle University civil engineering student who is set to spend his summer holiday in Uganda helping the Wider Mbarara Project 2010 to build a home for children orphaned by AIDS.
Around pounds 12,000 has to be raised towards construction costs and professional advice alone, with each student required to find a total of pounds 1,500 as their overall contribution.
Mr Wakeling, who heads Lodders' dispute resolution department, said: "AIDS is a terrible scourge across large parts of Africa and Uganda is one of the worsthit.
Steven and his fellow students are raising money for this very worthwhile cause and it deserves our support."
The four are hoping to raise several thousand pounds.
Mr Baker, Mr Wakeling and Miss Kang all took part in last year's event.
