Frequently Asked Questions
What to look for in a marathon training coach?
A great marathon coach should offer more than a one-size-fits-all plan. Look for expertise in endurance training, strength development, recovery, and injury prevention, as well as the ability to personalize programs to your goals and lifestyle. Data-driven guidance using tools like heart rate, pacing strategies, and VO₂ max is also a plus. At BeFit, our virtual membership gives you access to certified coaches who provide these elements in a structured way, with different levels of support so you can train smarter and reach the marathon finish line with confidence.
What is the 10-10-10 rule in marathon training?
This pacing strategy breaks the marathon into three mental and physical segments:
- First 10 miles: Controlled and relaxed — conserve energy.
- Second 10 miles: Hold a steady, sustainable effort — your true race pace.
- Final 10K: Dig deep and finish strong — this is where smart training pays off.
- It’s not just about surviving the distance — it’s about managing your energy wisely.
How much does a marathon training plan cost?
Marathon training plans can range from free generic schedules to premium programs costing hundreds of dollars per month. The difference is personalization and support. At BeFit, we offer a virtual membership with multiple tiers so runners can choose the level of coaching that fits their goals and budget. Whether you want a structured plan with progress tracking or a fully personalized program guided by a coach, our membership provides expert support at every stage of your marathon journey.
How to train for a marathon?
Training for a marathon goes beyond logging miles. A complete plan includes long runs to build endurance, tempo and interval sessions to improve efficiency, and strength and mobility work to keep the body resilient. Periodized training organizes these elements in cycles so that effort and recovery are balanced, helping you progress without injury.
Can you run a marathon without training?
Technically, yes, but it comes with real risks. While finishing a marathon is an incredible achievement, running one without proper training can lead to injury, dehydration, and long-term health issues. Instead, we guide you through a progressive, science-backed approach that helps you arrive at race day confident, healthy, and proud of the work you’ve done.
