Just make sure that you remember the following:
• Arrive in good physical condition.
Improve your overall physical condition at least one or two months before the trip. Train harder as the day neighbors. Ride regularly and combine it with weight training to develop muscle.
• Bring the right equipment.
Your backpack should include multi-tools (wrenches for nuts and bolts), tire repair kit (pump, spare inner tube, patches and glue), first aid kit, blanket / sleeping bag, flashlight, matches, cellular phone or satellite phone, and money.
If possible, assign someone to carry one or some items that need not to duplicated like multi-tools and pump.
• Wear the right clothes.
Being trendy is good but it is often unnecessary. Wear clothes that are comfortable and right for the weather condition.
• Check your bike.
Just like your car, mountain bikes need to be checked, especially if they are going for a long trip. Check the tires, suspension, chains, gears, brakes, nuts and bolts. Any small damage can become a big problem on the road. Replace parts that need to be replaced to minimize the chances of breakdown.
• Know the trail
Any season mountain biker would agree that experience and skill is no match with knowledge of the trail. Learn every curve, bend, dips, terrain condition, and everything that can be learned about the trail. This way, you will be able to plan your sleep and anticipate danger even before you arrive in the area.
• Take extra caution
Wear your helmet and gloves. Keep your speed in check. Do not ride too fast. Keep in control of your bike and plan your crash at all times.
• Inform a family member or a friend about your trip
Write down everything about your trip including, the location, your itineraries, and expected time and day of return.
• Do not ignore safety warnings
Most biking trails have rules, safety warnings and marks. They are designed for your safety so make sure that you follow all of them. There are places where you can bend or even break the rules; this is not one of those.
• Do not ride beyond your skill
Most beginners commit one common mistake: becoming too proud of themselves. This can be dangerous as they try stunts and stuff that are beyond their capability. Remember, there is no shame on walking and carrying your bike if you are not comfortable riding on it. If you are not sure that you can cross rivers or travel cliffs on your bike, do not even attempt to do it.
• Do not try anything stupid
If you do not want to be airlifted and spend several days in the hospital, then make sure that you keep your actions checked. Never ride alone. Keep up with the pace of the group. If you think you are the weakest person, insure that you ride in the middle of the pack. If you think you are the strongest, then do not think that you can do everything you want. Stay as a team at all times. Do not ride ahead or behind of the main party.
