Preparing for a multi-day expedition

Choice of route: Depending on the objectives of the expedition, the route should be carefully selected taking into consideration factors such as difficulty, distance, and nearby natural or cultural points of interest.
Map reading: Proper understanding of how to read a map is essential. This includes understanding symbols, features, and ability to estimate time and distance.
Emergency routes: Always have a plan for how to quickly reach safety in case of emergency. This could include identifying nearest medical facilities, escape routes etc.

Checklist: Create a detailed checklist of all the necessary equipment and supplies required for the expedition. Include everything from camping equipment and navigation tools to first aid kit and food supplies.
Equipment condition: All equipment should be thoroughly checked for wear and tear. Anything that is found to be in a substandard condition should be replaced.
Balancing the load: Distribute weight evenly in the backpack to make carrying it more comfortable and to reduce the risk of injury.

Food quantities: Calculate approximate food requirements based on the length of the expedition and the amount of energy you expect to expend. Always bring a bit extra, just in case.
Preservation: Select foods that are lightweight, non-perishable and easy to cook. Foods in pouches or cans can often be eaten cold if necessary.
Water purification: Always have a method for purifying water, whether that be iodine tablets, a small stove for boiling, or a water filter.

Fitness levels: Assess your current physical condition and make sure it matches with the demands of the journey.
First Aid: A well-stocked first aid kit is crucial, as is the knowledge of how to use everything in it. Recommended items include bandages, plasters, antiseptic wipes, tweezers and painkillers.
Weather conditions: Research and understand the expected weather conditions during the expedition and plan accordingly.

Permissions: Obtain any necessary permissions or permits required for your journey. This might include landowner permission, or special permits for protected areas.
Leave No Trace principles: Familiarise yourself with the principles of Leave No Trace camping, which include disposing of waste properly, leaving what you find, and respecting wildlife and other visitors.
