We’re now running a regular weekly photography assignment in the Observer New Review and the next theme is ‘fast.’ So whether its a memorable day at the races, abstaining for lent this year or a special moment that disappeared too soon, share your photos of what fast means to you – and tell us about your image in the description box.
The closing date is 26 March at 10 am. We’ll publish our favourites in The New Review on 29 March and in a gallery on the Guardian site.
You can share your ‘fast’ pictures by clicking on the blue ‘Contribute’ button on this article. You can also use the GuardianWitness smartphone app or the Guardian app and search for ‘GuardianWitness assignments’ – and if you add it to the homepage – you can keep up with all our assignments.
