Filipino W?J, 24, admitted being under the influence of alcohol when he hit three cyclists near Safa Park.
One of them, popular triathlete Roy Nasr, 49, a Lebanese expatriate who lived in Dubai, died at the scene.
His training partners, Briton S?Z and American A?T, were injured in the accident, at about 5.30am on September 6, and required hospital treatment. All three were hit from behind.
The driver confessed at Dubai Traffic Court to five charges - causing death, risking a person's safety, damaging property, drink-driving and illegal consumption of alcohol. He also apologised to Nasr's family.
As well as his prison term and blood money, his licence was suspended for three months.
The judgment is subject to appeal within 15 days.
Nasr's death sparked an outpouring of grief among the triathlon community in Dubai and a number of memorial events have been organised in his honour.
The Roy Nasr Memorial Super Sprint and Sprint Triathlon takes place at the Jebel Ali Gold Hotel on October 12 and is already sold out.
The winner of the race will be awarded a special memorial trophy in Nasr's honour.
