Friction or rubbing of the skin is often the cause of blisters, especially over long distances. You can prevent them by choosing the correct shoes and socks (made of moisture-wicking synthetic blends), using lubricants and being aware of ‘hot spots’ when they occur.
Hip and knee injuries
Trekking exerts pressure on hips and knees, especially when going downhill. Walkers who do too much too soon can develop IT band syndrome and patellar tendonitis. Avoid this with preparation via a good training schedule. Trekking poles can also help to support your joints.
Cuts and scrapes
Hikers encounter varied terrains so be careful underfoot. Gloves can also help avoid scrapes from low hanging branches or rocks. Always carry a first aid kit to be safe and watch for infection.
Little and often is a good mantra to staying hydrated. Sip sports drinks as well as water or eat salty snacks to replenish lost electrolytes.
