8 WEEKS TO STRENGTH, ENDURANCE AND CONFIDENCE
Base Building Training PLAN
Base building is where every runner starts — whether you're lacing up for the first time or coming back after time off. Base building is all about building the foundation before starting a build so that training can actually be fun! We offer 8-week training plans helps you build aerobic fitness, develop consistent habits, and lay a solid foundation for whatever comes next. No pressure. No burnout. Just smart, supportive training designed to help you feel strong and capable.
What is a base building running plan?
A base building running plan is a structured training plan designed to establish habits, build aerobic fitness, and build endurance for runners. The primary goal of a base building plan is to slowly and gradually increase mileage/time spent running and overall aerobic capacity (Aerobic capacity is the measure of how efficiently your body can use oxygen to produce energy during activities like running, jumping, and playing. Feel like you’re out of breath running down the block? That’s aerobic capacity. With training, you build endurance!), preparing the runner for whatever they hope to train for be it a 5K or a marathon.
Base building plans typically focus on increasing weekly mileage through a combination of conversational-paced runs, long runs, and cross-training activities. These plans often incorporate a gradual progression of mileage and intensity over several weeks, allowing the runner's body to adapt and build strength while minimizing the risk of injury or burnout.
Additionally, base building plans include runner specific strength training exercises to improve muscular endurance and prevent imbalances or weaknesses that could lead to injury as well as flexibility and mobility work to support overall athletic performance and recovery.
Base building is essential for runners of all levels, from beginners to experienced athletes, as it provides a solid fitness foundation that can support more advanced training and racing goals. By following one of our base building plans, runners can improve their overall fitness, endurance, and resilience, setting themselves up for success in their running journey.
