What's God got to do with surfing? Well, everything at least according to Nachum Shifren, better known to LA longboarders as the surfing rabbi.
In this quirky documentary, he takes us on a journey to the place where sport meets spirituality.
He argues that the discipline and self-abnegation of surfing are analogous to the requirements of orthodox Judaism.
His story is paralleled by those of followers of the mystic Sri Chinmoy.
They believe that one path to enlightenment is by running huge distances in self-transcendence races.
We join them at an extraordinary track meet in South London as runners compete to cover the furthest distance in 24 hours.
