MORE than 3,700 participants pounded through the heart of the Central Business District on Sunday to tackle the Men's Health Urbanathlon.
Starting and ending at the Kallang Practice Track, the gruelling 14km course featured nine obstacles, including a narrow see-sawing plank, squeezing through hanging tyres and traversing a slackline.
A Mystery Obstacle, revealed only on race day, required competitors to climb up a six-metre structure and jump from a two-storey height to end the race.
Participants, aged between 18 and 68, included Minister of State (Trade and Industry) Teo Ser Luck, mountaineer Edwin Siew and "Blade Runner" Shariff Abdullah.
Mr Teo, 46, said: "I had a lot of fun clearing the obstacles. It's unlike any running race.
"The Mystery Obstacle was really fun, especially the part where you jump down. I also had fun at the obstacle where you slide down a rope like a fireman."
This year's individual category was won by Nepalese Gurung Nimesh in a time of 54 min 35 sec. He walked home with over $7,000 worth of prizes.
More than 160 teams, comprising between three and five runners, raced in the corporate category. Team Gurkha came out tops, while the Ministry of Home Affairs and Singapore Police Force took second and third spots respectively.
In its sixth year, the Urbanathlon is jointly organised by SPH Magazines and HiVelocity, and presented by Tigerair.
Ms Pang Lee Cheng, general manager at SPH Magazines, said: "It's heartening to see everyone having fun, and meet loyal readers and participants who keep coming back year-after-year.
"We'll ensure the race continues to pique the interest of Singapore's running community. The support from our sponsors is also testament to a successful event that provides a platform for all parties while promoting health and fitness."
