Day 4 started out with the usual briefing where the instructions to enter the `Twilight Zone' were revealed. A seven kilometre stretch where the choice was given for the competitors either to go through this difficult terrain or to backtrack. The media was also given the choice either to backtrack, or to hike the seven kilometres.
The convoy lined up to twilight zone with the Land Rover team from Philippines leading the way followed by the Lankan team. Rest of the convoy consisted of Malaysia, Hong Kong and China consisting of a total of 13 vehicles entering the twilight zone.
The twilight zone lived up to its reputation from the very beginning of the trail. As the trail progressed, the terrain became muddy and narrow. At every hill, winching was necessary for the Lankan car whereas better prepared vehicles such as the Philippines and the Malaysian team contended the essence with much ease. The tropical rain started descending making matters worse and separating the convoy where the river rose and the part of the convoy had to turn back.
With the rain drenched trails every climb needed at least to be winched four times. While the lead car was not to be seen ahead, the Malaysian car was promoted up the order to lead the convoy. Also a team from Hong Kong contributed to the recovery, bringing in the true sense of team work which was the right formula to get through the twilight zone.
