When it comes to mountain marathons like the OMM, or LAMM there’s a myriad of factors that influence how quickly you’re going to get around. Some are down to personal skills and training, and these can only be improved the old fashioned way – by slogging around the mountains in whatever spare time you have. One of the biggest factors though is the weight of the kit you’re carting around. As a result, mountain marathoners often go to endless lengths to shave off a few grams where they can. uite
