Better start training for the Spartan Race. 

Ticked the triathlon box already? Then test yourself against the international craze for endurance obstacle course races.

The US-born Spartan Race (www.spartanrace.co.th) makes its debut in Thailand this Sep 9 at the Siam Country Club in Chonburi (home to Wonderfruit), where participants will test themselves against 20-23 military-style obstacles over five kilometers. Challenges include mud traps, barbed wire, walls, rope climbs and even fire pits. 

There are five different ability levels for men and women (starting at B1,650), but the best athletes will be in the Elite category, which you can now sign up for at the early-bird rate of B2,250.
