Night before the ride
Before the ride, it is a good idea to load up on carbohydrate-rich foods the night or even 1 or 2 days before. Stay away from foods that contain too much sugar. Sugar will give you a sudden energy boost but will also leave you in a slump after the effect wears off. Fruits such as oranges, apples, and bananas are also highly recommended both before, during, and after the ride.
Sweating during the ride will make you thirsty from dehydration. Drink a good cup of water before the ride begins but don’t drink too much. The human body takes up to two hours to absorb water and you don’t want a water bottle’s worth of liquid sloshing around in your stomach. As you ride, take periodic sips to keep yourself hydrated. If you wait until you feel thirsty, you’ve waited too long.
Isotonic drink such as Suntonic or 100-Plus is good as it replenishes the salt in our body.
You need not worry about packing enough food and water to last you the entire trip. G club provides water stations mid-way (depending on route) where you can replenish your depleted water.
Sleep early and get up early the night before. If you are participating in the Round Island ride, you must be at the checkpoint 6.15am. Therefore getting up 2 hours before to prepare and gear up your body for the ride is a good idea.
Your bicycle
Check your bicycles for brakes, adjust your seats and put enough pressure to your tyres. Make sure your bicycle tyres pressure are really well inflated rock hard (abt 120) because there are stretches near Genting where construction are going on and your bike got to go over striated concrete.It is the cause of many punctures esp if tyres are underinflated. Oil the chain and gears if possible.
Enjoy your ride ! Remember, this is not a competition, it is a joy ride ! So have fun !
