Wayne Dill’s diary of his participation in the gruelling Kota Kinabalu Challenge in Borneo continues here when, on day four, he experiences white water rafting, and a friend from Beijing repeatedly injures himself in strange and unusual ways. Mr Dill took part in the challenge to raise money for Raleigh International Bermuda. For more information about Raleigh see www.raleigh.bm .Day 4: Tuesday, March 6, 2012We break down the camp and begin a two-hour trek out of the jungle. We walk along the river and the lush greenery is beautiful. There are several river crossings and the weight of my rucksack lets me know that my fitness is lacking. Every step has to be deliberate and sure. There have been a few falls and this serves to remind me that nothing can be taken for granted. I struggle to focus my efforts given the heat and narrow foot paths.At a river crossing we come across a moon rat in a hunter’s snare. The guide Floyd pulls his machete and I push on past not wanting to see the animal harmed. I learn that Floyd released the animal to everyone’s relief. As we walk through a village Jerry from Beijing strikes his head and manages to acquire two gashes in his scalp. Crispin is in disbelief “How the hell do you walk into the only building on the trek and strike the edge of the roof!” Stephen our medic patches him up and we arrive at the check point.When I drop my rucksack to the ground I feel like I can float into the sky. The sensation of weightlessness is overwhelming and short-lived. We must get ready for the 8K bike and run race. There are cool energy drinks and fruit and I can’t satiate either my thirst or hunger. Each team has to manage how they’re going to complete the race. I stick with Dueane (Dill) who is struggling with a foot injury. We decide to run 2K, bike 4K and finish with the mandatory 2K run. Teammates Philip (Faries) and Liza take off on the bikes. This run course is brutally difficult. At one point Dueane pushes on a tree and it falls off the bank into the river below a drop well over 30 feet. Jerry is again injured when he falls off his bike going down a hill.Dueane gallantly struggles through the course with his injured foot and cramps. The run finish is next to the river and there are waiting rafts for each team. We have a guide on the raft to help us navigate the category two rapids of the Kiulu River. We are given two hours to paddle to the next check point where the race through the rapids begins. At a calm bend in the river most teams jump in the water and float down river next to the raft. The spontaneous dip is cool and refreshing. The Kiulu River is amazingly beautiful. We drift by water buffalo, monitor lizards and vibrant splashes of colour flutter by as butterflies or hang from trees as exotic flowers.At the checkpoint we race down the rapids for 4K. Liza acts as coxswain calling out the beat that we paddle to and we finish just behind the winners by two seconds. The finish is at the TAC and one of the most action-packed and activity intense days I’ve ever experienced is over.I wash what I can in the river and after a cold shower I have my last set of clean dry clothes. Everyone else has the same idea and the eating area becomes an endless string of hanging laundry.At dinner the camaraderie is very high. Common experience gives rise to friendship. Crispin presents the summary of scores and our Team Six is in last place.
