Contestants at this year's Men's Health Urbanathlon will be pushed to their limits once more with five new obstacles and a mystery challenge.
Pang Lee Cheng, general manager of Singapore Press Holdings (SPH) Magazines, said: "The Men's Health Urbanathlon has grown from strength to strength in the last five years.
"This year's edition promises to be our toughest ever, and should provide a thrilling challenge for Singapore runners."
While the dreaded uphill monkey bars is missing from the March2 race, new obstacles like the Wire House - a 4m-long web of bungee cords - and Peaks and Troughs - 3m-high sloping structures - mean there is no respite for racers. Adding to the intrigue is the mystery challenge, which will be revealed only on race day.
Registration for the race, jointly organised by SPH Magazines and HiVelocity and once again open to women, has already exceeded last year's figures.
Said Kelvin Tan, editor of Men's Health: "We have already exceeded the 3,000 number of participants from last year's race.
"However, we are keeping registrations open till this Friday so that even more running enthusiasts can join us and experience for themselves how memorable the Urbanathlon is."
Back for more is Singapore runner Anne Qi Hui, who finished in 1hr 8min 57sec last year.
The 33-year-old said: "The race tends to bring out the best in me. Endurance, speed and focus are required to finish the race, and it is important to use the right strategy for each obstacle.
"Of course, it's important to have fun at the same time."
Joining Qi are Singapore's "Blade Runner" Shariff Abdullah, and the seven-member Team Singapura Everest, who are aiming to scale Mount Everest next year.
Hiwan Idus, member of Team Singapura Everest, said: "We are confident that our training for Everest will put us in good stead for the Urbanathlon."
Registration fees are priced at $128, and each participant will receive a race pack worth over $400.
