This is a time based plan designed for intermediate-advanced runners looking to build an effective base and complete a half, full, or ultra marathon in the future. It is a structured plan with built in recovery weeks. It has 2 suggested strength training sessions, 3-4 running sessions, an occasional bike session, and 3 rest days each week. It begins with short-moderate length runs and progresses to a 2 hour run at maximum. The focus of this maintenance plan is on training your aerobic base and VO2 max. The goal each week (outside of testing week and recovery weeks is to get in 3 aerobic sessions of 45+ minutes zone 2 work and a single VO2 max session. There are also notes included throughout the plan to give you recommendations for practicing fueling and hydrating properly. There is a threshold pace test included at the beginning and end of the training plan so you can see your progress over the 2 month period. 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 don't want to do the threshold test, 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.
