Obiter recommends the record 12,000 walkers taking part in this evening's London Legal Walk grab a bottle of free water being handed out by the Law Society before they embark on their 10km charity trek - temperatures are set to reach a balmy 24 degrees in the capital this evening.

An impressive 699 teams have signed up for this year's annual event organised by the London Legal Support Trust charity. Last year 10,000 walkers helped to raise £740,000 towards free legal advice services.

Society president Robert Bourns said the walk is a 'great way for us to come together to support charities that provide legal advice day in, day out, helping a hugely diverse range of people, many of them vulnerable and facing frightening legal situations'.

Money raised will enable law centres, local Citizens Advice and other advice agencies who help, for instance, families facing homelessness, older people requiring community care, trafficked women and children, people with disabilities, refugees, and those facing unemployment or mental health problems.

Sir Terence Etherton, master of the rolls, said: 'We will be walking to raise funds for free legal advice supported by the London Legal Support Trust. The need for these charities has grown over the past few years while resources for their work have diminished. That makes the funds raised by the London Legal Walk more important than ever.'

To reduce congestion on the pavements, this year's walkers have a choice of two routes: via the parks or along the river. Both start in Carey Street, ending inside the Society and at the street party in Carey Street/Bell Yard. Stewards will be on hand. 

Best of luck to everyone on their feet this evening. If you spot one of Obiter's colleagues from the Gazette - the official media partner, do say hello and have your best smile ready for our photographer.
