Dongola racing is a popular event in traditional local regattas, especially on the River Thames in southern England and was first competed at Maidenhead in 1886.
Dongola racing originates from Lord Wolseley's Nile Expedition of 1884–1885 to relieve Charles George Gordon at Khartoum.
Lord Wolsey offered £100 to the battalion that covered the 370 miles from Sarras to Debbeh in the fastest time.
The Royal Irish Regiment beat the Black Watch in a close finish.
Others may turn up on the day and treat the event in a light-hearted manner and in fancy dress.
