Acclimatization. The Everest Marathon is a high-altitude race held in a region with low atmospheric pressure and oxygen levels, with some parts covered by snow all year round. Thus, to avoid health risks like altitude sickness, snow blindness and cold allergy, runners often require some days for acclimatization in the race. Usually, participants are advised by the event organizers to stay around the region for a few days or even hike towards the starting point from Lukla. Some agencies even prefer the participants spending up to 7 days for  preparation of the trip. Participation number limits and ecologically conscious practices. To protect the fragile natural ecosystem around the Everest region lying within the borders of the Sagarmatha National Park, the number of participants are capped so as to prevent environmental problems arising from overcrowding. Typically, organizers cap the numbers at around 250 every year. The organizers also have integrated a concept making Everest Marathon a Green Event by applying waste minimization, as well as implementing clean waste disposal practices. Off-Road Trail. The Everest Marathon route consists entirely of off-road non-tarmac surfaces. Runners will need to navigate  through natural trails, stone trails, and steps, and sometimes even snowy and muddy trails. Thus, the route requires special clothing gears, and equipment for navigating the trails. Elevation drop. The total elevation drop between the start and finish points can be as high as 1620m. The lowest point in the route is at Laubisasa, which is located 3439m above sea level.
