Early Days

Ying Ren, or Mok as he is always known as was not very sporty in his early days. When young, he went to piano lessons, like most other children as learning music is  supposed to be good for a child’s brain development. He went on to play the Gu Zheng, a large chinese instrument as his Co-Curricular Activity in Red Swastika Primary School.


When he reached 11 years old, Primary 5, Mok learnt how to swim and eventually joined the SASA (Bedok) swim club. This marked the beginning of his swimming career which lasted about 6 years. His favorite event was the 200m butterfly and the 1500m freestyle. During his secondary school years in Raffles Institution, Mok was exposed to cross country when he took part in the Annual School’s Cross Country at Macritchie Reservoir 2001. This was his first exposure to running. In Secondary 1, despite still training as a swimmer, he came in 11th position in the Inter-School cross country competition. For the next 3 years in Raffles Institution, Mok remained training as a swimmer while also competing for the school in cross country races. He trained in several swim clubs such as Swim Fast Aquatic Club and Singapore Swimming Club.


In 2005, Mok entered Raffles Junior College. It was then he was also exposed to the rising trend of Triathlon in Singapore. He took part in his first aquathlon, and was drafted into the National Triathlon Squad. This was the beginning of his triathlon career. His first triathlon race was at A’Famosa, Malacca where he finished in 17th position (3 years later, he returned to the same race and won the event). Triathlon allowed him to travel to many countries to race such as Malaysia, Indonesia, Korea, China, Hong Kong and Taiwan. Each overseas competition added to his

experience in handling stress and competition. During this time, Mok was also coached by the RJC cross country coach, Mr Steven Quek who imparted alot of knowledge on the science behind training also also how to be an efficient student-athlete which is very important in Singapore.

 Medical School

In 2006, Mok graduated from RJC and was drafted into the Army for compulsory Basic Military Training at Pulau Tekong. After 3 months, he qualified for the Officer Cadet School. After 3 months in OCS, he managed to disrupt his military service to enter medical school at the Yong Loo Lin School of Medicine, National University of Singapore in July 2007.

SEA Games Gold

For the next 5 months, Mok self-coached himself with the assistance of several advisors such as Dr Kua Harn Wei and Mr Ramlan in the different triathlon disciplines and eventually went on to clinch the gold medal at the SEA Games in Thailand for triathlon.

After the Asian Beach Games in 2008 where Mok finished 12 out of 31 participants despite being a student athlete, he decided to change his focus towards pure Running as clinical years for medical schools start in Year 3 and that means more time spent traveling to hospitals and being on the feet for most times of the day. Running is less time consuming than cycling or swimming as there is no need for traveling to and fro the pool and one can run any time of the day.
