Cape Town - South Africa's Lebogang Shange and Wayne Snyman finished in 44th and 58th positions, respectively, in Friday's men's 20km race walk at the Rio Olympic Games.
A high school dropout and former farm labourer, Shange completed his campaign in a creditable 1:25:07, while Snyman's time was 1:29:20.
Only 63 of the 141 starters finished the gruelling competition, with more than half the field sidelined by attrition or disqualification.
Great Britain's Tom Bosworth led for much of the race before fading to sixth spot, while the in-form Caio Bonfim recorded a Brazilian record - 1:19:42 - in finishing fourth.
