Plain-language summary

Road marathon is a famous running race known for hundreds of years. Trail running is an emerging running discipline which count new runners every year. Trail running and road marathon are two running endurance disciplines which differed by variation of elevation and nature of the terrain. While marathon is essentially run on flat roads, trail races are realized on steep paths (mountain, desert…) with an important variation of elevation. Neuromuscular, biomechanical and physiological consequences are different depending on the discipline, especially with a greater eccentric contribution in trail running. In spite of this characteristic, trail runners take part in several races longer than 40 km per year, while road runners participate in one to two marathons per year.
