According to reports from Cornwall, it seems a dolphin off the coast of Cornwall might have been trying for a place in the British Olympic team albeit with limited chances as Zapcat powerboating isn’t currently part of the Olympic schedule.
The Zapcat powerboats are essentially inflateable dingies but with a powerful motor on the back (similar to those used by coastguards), but by all accounts the Dolphin which interupted proceedings for around half an hour, was doing significantly better at the sport than its human counterparts.
Perhaps out of sight, Dolphins have their own Olympics including with fairly familiar sports such as the 100 metres dash (underwater), hurdling over the waves and tag which isn’t admittedly an Olympic sport yet but give them time.
Eventually the Dolphin decided it’d shown them daft humans how to do things and moved on, allowing the races to continue. However, we’re still not sure if the Olympic rules actually prevent animal entrants.
