Plan Description

Coach Michele offers a complimentary phone call to answer questions.

Build strength, endurance, and confidence with this 18-week marathon plan designed for experienced runners ready to refine their performance.

This plan is ideal for athletes who have completed at least one marathon and maintain a base of 25 to 30 miles per week with a long run of 10-12 miles.

During the first six weeks, you’ll focus on deepening your endurance with Hill Repeats and Steady-State runs, followed by a 5K fitness test at the end of Week 6. Beginning in Week 7, you’ll transition to Tempo Runs, with guidance on how to integrate specific paces alongside or in place of training zones.

An optional Half Marathon in Week 11 allows you to practice race-day pacing, fueling, and hydration while gathering valuable data for your Marathon Goal Pace.

The plan also includes Core and Hip Stability and Strength workouts with video instruction.

Coach Michele is an RRCA Level II Certified Running Coach and Certified Specialist in Fitness Nutrition (ISSA). She currently trains for and competes in ultramarathons of up to 100 miles and has coached athletes to successful finishes at distances ranging from 5K to 200 miles.
