The Union of South Africa competed at the 1920 Summer Olympics in Antwerp, Belgium.

The team took three total medals, one of each color, with Rudd winning two on his own and being part of the relay that won the silver.

The South Africans took three medals, including silvers in the tandem (Smith and Walker) and individual time trial (by Kaltenbrun) and a bronze in the team pursuit.

The team pursuit medal was awarded due to South Africa having the faster time of the two semifinal losers.

South Africa won its first Olympic shooting medal, with the silver in the long-range team prone military rifle.

Winslow, the defending gold medalist in the singles, fell to Ichiya Kumagae in the semifinals and finished with the bronze medal.
