KAMPAR: Riders competing in the 30th edition of Le Tour de Langkawi (LTdL) face a daunting new challenge today as they tackle the formidable “mystery box” of Gunung Jerai in Stage 2.

The 145.6km route from Taiping to the 1,217m summit is a new addition to the race which will also include mountain tests at Cameron Highlands (Stage 4) and Genting Highlands (Stage 5).
