If it is climbed quickly enough and the walkers do not get lost they can return to the bottom by about nine o'clock. It takes several hours to get to Snowdon in Wales. The walkers are usually very tired and worried that there is not enough time. If they arrive at the bottom of Snowdon at half past one in the afternoon they can climb it in two hours. This leaves them an hour and a half to get back to the bottom. If they were too slow on the other mountains or the journeys in between they might have to run!
