The popularity of Mountain Biking (MTB) in Malaysia is increasing.This adds to the demand for more cycling sites and special events for MTB. In line the growing demand, the Malaysian government encourages participation in active sports and recreation as a healthy lifestyle. One of the approaches is through the establishment of the Putrajaya Challenge Park (PCP). This study is conducted at PCP, one of a well-known MTB site in Malaysia. It has a network of treks where these treks are rated with different difficulty level for cyclists to choose from according to their abilityandpreferences. MTB is known to be associated with risks and high technical skills, hence it is great interest to understand the factors affecting demand in such sport. Therefore, the purpose of this study is to determine the factors affecting the demand in MTB participation at PCP. Data was collected using a structured questionnaire and obtained a total of 302 usable questionnaires. A multiple linear regression analysis is employed and it is found that three factors were significant at 95% confidence level; total travel cost, years of participation and cost of equipment upgrades. The finding from the study is to supply PCP management with the information for future adventurous recreational events in PCP or in other similar establishments. This research also identifies some key findings and makes some recommendations for future research and management.
