The University of the Free State will hope to start developing their next Wayde van Niekerk when the first Varsity athletics meeting takes place on Friday at the Tuks Athletics Stadium in Pretoria.
The second meeting is on 23 March, also in Pretoria.
Thirteen members (five men and eight women) of the Kovsie team of 25 are still under the age of 21.
The hope for medals among the men would be on Sefako Mokhosoa (triple jump), Hendrik Maartens, and Tsebo Matsoso (both 200 m). Mokhosoa, who represented South Africa last year at the Southern Region Championships, is in red-hot form and achieved a personal best of 16.13 m at the Motheo/Xhariep meeting two weeks ago. This is currently the third best distance in the country for 2018.
Maartens would like to go one step further. In last year’s final Varsity meeting, he finished second in 20.62. Great things are expected of Matsoso, a first-year student who competed at the African Junior Championship in 2017. Last year, he was one of the top athletes at school level by winning the SA title in a time of 21.14.
Ts’epang Sello (800 m) and Elmé Smith (100 m and 200 m) will lead the charge for the women. Sello already came close to her personal best (2:09.8) this year, while Smith has also been running fast times. Her best this year was 11.88 (100 m) and 24.53 (200 m).
Tyler Beling (1 500 m) is another first-year student who is showing great potential. She obtained a fourth position at last weekend’s CAA Southern Region Cross-country Championships. Maryke Brits (100 m hurdles and long jump) is a possible medallist, despite running her first event for the year on Wednesday night.
The meeting starts at 17:15 and will be broadcast on SuperSport 5.

On 14 May this year, Dr DW Bester received a DPhil in Statistics from the University of Oxford. The entire ceremony, which was held in the Sheldonian Theatre in Oxford, was conducted in Latin, as has been the case for the past 800 years.
Dr Bester completed his undergraduate studies and his honours degree at the University of the Free State (UFS). “At first, I was only planning to study for a master’s degree, but was privileged to get an opportunity to do a PhD as well. I didn’t think twice!” he says.
Studies at the University of Oxford
Universities in England do not require a master’s degree for PhD studies. With the help of Prof Max Finkelstein from the UFS Department of Mathematical Statistics and Actuarial Science, Dr Bester registered for the DPhil programme in Statistics directly after his honours studies.
“The title of my thesis was: Joint survival models: A Bayesian investigation of longitudinal volatility. It dealt with a problem in the medical field to determine the cause of stroke risk: is it the absolute level of blood pressure, or the volatility thereof? The analysis of this question led to interesting models which needed advanced application techniques. I had to study these techniques and write programmes for their application.
Although Dr Bester is working currently as the technical head of a company that calculates insurance for power stations, satellites, rockets, and cyber risks, he would like to continue working with his Oxford supervisor in future to make the techniques they have developed more accessible for researchers outside of the field of statistics.
“Studying at Oxford requires hard work, perseverance, and a lot of luck. Luck plays a big role, since there are no guarantees that hard work will ensure you a spot in one of the top universities.
Regarding his studies at Oxford, Dr Bester thinks back on his exposure to the GNU/Linux operating system, and free software. “I have seen how valuable this is for analyses in practice. I also had the privilege of meeting the father of free software, Richard Stallman,” Dr Bester says.
2011 Rhodes Scholar
He was elected as Rhodes Scholar in 2011. According to Dr Bester, who has been interested in Mathematics since high school, the Rhodes scholarship was something of a fluke. He applied for the Rhodes scholarship on the recommendation of Prof Robert Schall of the Department of Mathematical Statistics and Actuarial Science.
Role of the UFS in his successes
In addition to the continued support from the team of passionate professors and lecturers at the UFS, the actuarial degree at the UFS is fraught with statistics. Emphasis is also placed on Bayesian statistics. This was crucial to his studies at Oxford. According to Dr Bester, this topic is emphasised strongly in the international statistics community.
Dr Bester regards the work done by two of his lecturers, Michael von Maltitz and Sean van der Merwe, among his highlights at the UFS. Since our first year, they have created an atmosphere of camaraderie among the students. “I think this contributed to the success of everybody. They also make an effort to present topics outside of the syllabus regularly,” says Bester.
