Viper challenge is a 20km challenge course, filled with 20 man-made obstacles that will challenge both heart and spirit. It is Asia's perennial obstacle challenge, like no other. Designed to take you out of your comfort zone, you enter the challenge either as an individual warrior or as part of a team... Whichever way you enter, you will finish understanding that only teamwork will get you across the line, without it you are unlikely to succeed. Viper Challenge is set to be one of Malaysia’s most exciting events for 2013.
