SINGAPORE - Ms Lizzy Hawker, five-time winner of The North Face Ultra Trail du Mont Blanc mountain ultra-marathon, is surprised by the healthy interest in ultra marathons in Singapore.

The 38-year-old Briton, in Singapore for the first time to attend the inaugural Runners Convention last week, said: "I think that Singapore is a city and I didn't actually realise that there are trails to run on."

Ms Hawker, who has not been running for the past six months due to injuries, managed to run on the trails at MacRitchie Reservoir and Rifle Range Road.

For an ultramarathoner like Ms Hawker who has run in some of the world's toughest races, covering 166km, with elevation of 9,600 m, in just 25 hours, the trails in Singapore are considered easy.
