COLONEL John Blashford-Snell is one of the world’s most renowned and influential explorers.

Often cited as an inspiration by the likes of Ranulph Fiennes and Bear Grylls, he has spent decades at the forefront of British expeditions.

His achievements include the first descent of the Blue Nile in Ethiopia, an arduous crossing of the Darien Gap and the first navigation along the full length of the Congo River.

There will be a chance to hear about these daring exploits first hand when he visits Abingdon School on Thursday to speak at the Amey Theatre from 7.30pm.

Tickets are available via the school website.
