Looking to build up from running marathons or your first ultra up to a more mountainous ultra? Then look no further than this 20 week training plan designed with the Lakeland Trails 100k in mind so targeting a 100km distance over fairly technical terrain with 3,200m/10,500ft of ascent over 5 mountain passes.

With a maximum of 6 runs per week, including plenty of hill training, this training plan is designed for the runner that is running regularly and capable of running a marathon as a minimum. Week one total volume is 34km & 300m/900ft of ascent with the biggest volume week of 88km & 3,200m/10,500ft of ascent. Ideally you will need access to train on local mountains/hills to be able to replicate the ascent and technical terrain required. It is possible with just training in a city using stairs but much more effective with the appropriate terrain.

This training plan will include videos and tips to help guide you on topics such as nutrition, hydration & kit for race day and suggested strength and mobility sessions to work in alongside your running plan.
