Gerda Steyn, a former student at the University of the Free State, won her first Comrades race on Sunday, setting a new course record.
Winning the Comrades ultra-marathon is the greatest honour of her life and still feels unreal, said Gerda Steyn a day after winning the race in a record time.
 
The former Kovsie student had an incredible race on Sunday, completing the 86,83 km’s in a time of 05:58:54, which is a new record for women in the up run. It is more than 10 minutes faster than the previous record of 06:09:23 set in 2006.
 
It was also the fourth fastest Comrades time ever by a female in the 94-year history of the race.
 
Greatest honour of my life
 
“Being the Comrades winner is the greatest honour of my life. Thank you to an entire nation for carrying me to the line. It feels like a dream,” Steyn said.
 
The 29-year-old Steyn became the first woman in 30 years to win both the Comrades and Two Oceans in the same year. She also won the Two Oceans in 2018 and came second in the Comrades last year.
 
Steyn, who studied Quantity Surveying and Construction Management at the University of the Free State (UFS) between 2009 and 2012, said the record time was discussed beforehand.
 
I went for it
 
“We felt it was possible, but it wasn’t my main goal right from the start of the race. At the halfway mark, I saw it was possible and I went for it.”
 
According to Steyn, the media attention since her win is quite intense. “But I don’t complain. It is such an honour, so I do it with a smile.”
 
At the Two Oceans ultra-marathon in April, she missed out on the 30-year record time by just 53 seconds.
 
Prof Francis Petersen, UFS Rector and Vice-Chancellor, said Steyn was a proud ambassador of the university. “It is always important for me to see how our former students perform. I would like to congratulate her. Well done. She is carrying the Kovsie name with pride,” Prof Petersen said.

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
