|Rugby union career|
Marais was born in the town of Somerset East and grew up on a farm near Cookhouse. He attended Gill College in Somerset East, a school that also produced the Springbok brothers Willie and Michael du Plessis. After school he went to study agriculture at the prestigious Stellenbosch University, with the intention of becoming a veterinarian. Later on he did his doctorate at the University of Port Elizabeth, the forerunner of the Nelson Mandela Metropolitan University.
In his schooldays he was a loose forward, but was converted into a prop by Danie Craven when he went to Stellenbosch.
At provincial level, he represented Western Province as well as now-defunct North Eastern Cape and Eastern Province.
After retiring from first-class rugby, he continued to play for his hostel team at university for five seasons and stopped playing altogether just shy of his 40th birthday.
Life after rugbyEdit
After his retirement from playing, he coached the University of Port Elizabeth's as well as the Eastern Province under-20 sides and was also the assistant coach to the Eastern Province senior team for a while. He served as a Springbok selector from 1982 through 1986, and then again from 1993 up to the 1995 Rugby World Cup.
