The walkers, including several parents and teachers, gathered at 8 am at the first layby on the Esplanade, where this year’s 36-mile walk was started by Denis Le Breuilly, who is retiring this summer after nearly 40 years service to the school.
More than £20,000 was raised on last year’s walk, £10,000 of which went to local and international charities including the Lasallian Developing World Projects, Indian orphanages and educational projects in Kenya.
This year the first £3,000 raised will be divided equally between the Jersey Kidney Association and the Pakistani Earthquake Fund.
Checkpoints have been set up at three-mile intervals and will be manned by parents, pupils and staff.
Motorists are asked to be wary of walkers on all coast roads up to 10 pm tonight.
