Early career

Jason Dunford started swimming competitively in 1991, at the age of five and it was while at Kenton College, a primary school in Nairobi, under coach Andrew Nderu, that he began to establish himself as a top swimmer in age group for the region.^[2] At 13, the talented swimmer moved to study on a scholarship at Marlborough College in the United Kingdom.^[4]

Dunford competed in various races at the 2004 Short Course World Championships in Indianapolis, and 2005 World Championships in Montreal, but the young swimmer failed to advance past the heats.^[5]

While at Marlborough College he met coach Peter O'Sullivan, himself a former Great Britain International Swimmer in the 400 m Individual medley. O'Sullivan had swum at the University of Georgia, and it was he who encouraged Jason to look to college in the US to develop his swimming career. In 2005, after finishing his A-Levels, Dunford moved to Stanford University in the United States where he earned a swimming scholarship. In 2009, he graduated with a BA in Human biology,^[6] in 2012, he completed his MS in Earth Systems, and in 2016 he returned to the same campus, graduating with his MBA from the Stanford Graduate School of Business in June 2018.

In Shanghai he reached semi-finals in two events: 100 metres freestyle and 100 metres butterfly.^[7] He missed the 2006 Commonwealth Games due to a conflict with preparations for his first NCAA Championships.^[8]

The 2006 African Swimming Championships in Dakar, Senegal, marked a breakthrough moment for him as he became the first Kenyan ever to win a continental swimming medal with gold in the 100m butterfly on the first day of competition. He went on to finish the competition with two gold medals (100m butterfly and 50m backstroke), three silvers (50m butterfly, 100m and 200m freestyle) and one bronze (50m freestyle).^[6] He also broke a number of national records. His younger brother David Dunford also performed well, winning two golds and one silver (100m backstroke, 200m backstroke and 50m backstroke).^[9]
