Imagine running from Tuas to Changi seven times over four days, along a route that includes mountains and forests. That's the 345km challenge Mr Lim Nghee Huat has set himself in August when he competes in Ultra Great Britain. The race across Scotland is the longest event the 65-year old has participated in during his 12 years of running for good causes.

This year, Mr Lim is raising funds for the Tan Kim Ping Academic Fund under the SingHealth Duke-NUS Radiological Sciences Academic Clinical Programme (RADSC ACP) to support its medical research and education initiatives.

Mr Lim, who has tackled the hottest and toughest races on the planet, says that each race comes with its unique challenges, but it is the cause he is running for that always keeps him going.

"This year, I wanted to choose a beneficiary that is marking a milestone and making a difference. I'm running for Radiological Sciences because I believe this medical specialty is one that really helps many people by detecting what illnesses they have," says Mr Lim. "I think that medical research and education in this field are critical so that new methods can be developed for earlier detection of diseases."

The fund hopes to raise $250,000 through the support of Mr Lim and other fundraising initiatives.

Professor Tan Bien Soo, Academic Chair of the RADSC ACP describes Mr Lim's passion for running and spirit to raise funds for charity as truly inspirational.

"We are extremely privileged to have such a prominent runner race for our cause. Almost everyone would have some form of contact with the field of Radiological Sciences over his or her lifetime. Radiological Sciences supports all medical specialties in determining accurate diagnoses and in monitoring patients' responses to treatments. We are grateful to have Mr Lim's support as we continuously strive to advance the way we see, understand and treat the human body," says Prof Tan.

To cheer Mr Lim on from Singapore, over 500 SingHealth and Duke-NUS Medical School staff, family and friends will gather for The RAD Race, a non-competitive 3.45 km run organised in tribute. The RAD Race is a part of the RAD FUNdraising 2018 campaign, and will take place on Sunday, 19 August 2018, at Punggol Waterway Park, in tandem with Mr Lim's ultramarathon race.

Dr Tan Kim Ping pioneered Radiological Sciences in Singapore and headed the Department of Diagnostic Radiology at Singapore General Hospital from 1991 to 2002. During his illustrious medical career, he spearheaded many changes in the field locally, such as introducing the availability of 24/7 radiology services. He also mentored numerous radiologists, many of whom currently hold leadership positions in various healthcare institutions. 

The Tan Kim Ping Academic Fund aims to continue Dr Tan's legacy of innovation by spurring discoveries in new imaging technologies and procedures to improve outcomes. Areas of research the fund will support include developing innovative and cost-effective treatments for renal dialysis access, and limb ischaemia to prevent amputations in people with diabetes. The fund will also be used in the fight against cancer to develop targeted tumour therapies and to study the effectiveness of new treatments through imaging.  The Fund will build on Dr Tan's passion in medical education and research to equip radiologists with the skills and knowledge to serve future generations and discover new imaging technologies and procedures to improve patient outcomes.
