The finest minds from across the globe will be flexing mental muscle for the next three days in Croydon.
The World Memory Championships, which get underway today at the Croydon Conference Centre today, will see competitors from 32 counties put their brains through the paces and test their powers of recall.
Among many other pursuits, contestants will be challenged to remember a sequence of more than 4,000 binary numbers, recall the order of a pack of cards in just a handful of seconds and remember the dates of historical events.
Croydon is hosting the 22nd annual Championships because Chris Day, the general secretary of the World Memory Council, lives in Waddon.
