This 12-week training plan is designed for beginner to intermediate runners who want to build consistency, durability, and confidence without rushing the process. The goal is simple: gradually build up to 50 miles per week by Week 12 in a way that is sustainable and realistic.

The plan follows a slow, steady mileage progression, prioritizing easy and regular runs only. There are no workouts, intervals, or complicated sessions—just running at a comfortable, conversational pace. This approach allows the body to adapt naturally, reduces injury risk, and helps athletes develop a solid aerobic base.

IMPORTANT NOTE: Easy run pace should NEVER feel like you're wearing your body down. If you are running with someone else, it should be very easy to talk with them without feeling out of breath/more tired. You can feel free to pick it up a little on the pace, but this plan is mainly just to build up a solid mileage base.
