This is a mileage based plan designed for intermediate runners looking to complete a half marathon. It is a structured plan with built in recovery weeks. It has suggested strength training days and at least one full rest day each week. It begins with shorter runs and progresses to a 12-mile run before tapering for the race. Various runs are included in the plan to help you progress safely and quickly to achieve your goal. There are also notes included throughout the week to give you recommendations for practicing fueling and hydrating properly. There is a threshold pace test included about halfway through the training plan. Your threshold pace can be updated in training peaks which would change the paces for your training as the workouts are set up based on a percentage of your threshold pace. If you want, you can perform a threshold test prior to this plan. Otherwise I would recommend estimating your threshold pace by estimating what pace you could sustain for a 30-minute solo run at your hardest effort, or what you could do in a 60-minute race. This should be current though. Not what you have done in the past.
