Effort-Based: Lake Sonoma Trail Marathon - Goal of Finishing


Greg Marshall


16 Weeks

Plan Description

This plan is for the beginner to intermediate runner aiming to complete the Lake Sonoma Trail Marathon. You can check out the companion blog post here:

LS26.2 is run on soft single track trails around Lake Sonoma in the heart of scenic California wine country, and this plan makes sure that athletes will be ready to handle the demands of a course that's been referred to as "death by a thousand hills".

This comprehensive 16-week plan will help you to physically and mentally prepare to cover the 26.2 mile race distance and it's 6,000ft of vertical gain and loss. Even if you've never run any race longer than a road half marathon, success at the LS26.2 is in reach with this plan.

Features of this plan include:

-5 training sessions in an average week with two days of pure rest.

-Detailed workouts that will prepare you for a trail running race even if you don't have access to trails or long hills for training.

-Weekly Training Tips to help support your running through nutrition, recovery practices, and mental preparedness guidance

-Attainable long runs and interval workouts specifically targeted at preparing you for the many hills on this race course.

-Fully structured workout execution with compatible devices

This plan uses effort-based (RPE) targets so that you can easily manage your workout whether you're doing it on technical trail for fast-and-flat pavement. For the Heart Rate-based version of this plan, see this page:
