OSCAR's Inflatable 5k is a charity fun run featuring large inflatable obstacles. The York event takes place at Elvington Airfield. It's a 5k in a relaxed, fun way: participants bounce, slide, and leap through the course to raise funds for OSCAR's Paediatric Brain Tumour Charity, supporting children with brain tumours.
The charity considers the York run its main Inflatable 5k, also directing supporters to similar inflatable 5k events in their areas. Fundraising is integral to the event; one participant page showed £945 raised from 39 supporters, exceeding a £125 target, and one campaign aimed for £10,000.
