First Section: Advantages and Challenges of Treadmill Training
Advantages of Treadmill Training
Treadmill training has unique benefits. Firstly, it's unaffected by weather conditions, allowing you to train indoors regardless of rain, snow, or extreme heat. Secondly, treadmills allow precise control over speed and incline, helping you manage training intensity and pace effectively. Lastly, treadmill running can reduce joint impact, lowering the risk of injury.
Case Study: I have a friend, John, who lives in New York. During winter, the cold and pollution made outdoor running impossible. He switched to treadmill training, which not only shielded him from harsh weather but also helped him complete his first half marathon in 12 weeks.
Challenges of Treadmill Training
However, treadmill training also presents challenges. Firstly, the experience differs from outdoor running, which might feel monotonous. Secondly, the changes in incline and speed might not mimic the natural variations of outdoor running, making training somewhat repetitive. Lastly, treadmill running might overlook some running techniques like stride and posture adjustments.
Reflection Question: Have you encountered these challenges with treadmill training? How did you overcome them?
Second Section: Jack Daniels' Training System
Introduction to Training Phases
Jack Daniels outlines five primary training phases in his "Running Formula":

E (Easy Run): This is foundational training aimed at improving aerobic capacity and endurance. Intensity is low, typically 60%-70% of your maximum heart rate.
M (Marathon Pace): Simulates race pace to help you adapt to half marathon rhythm. Moderate intensity, usually 70%-80% of max heart rate.
T (Threshold Run): Increases lactate threshold, enhancing endurance. High intensity, typically 80%-88% of max heart rate.
I (Interval Run): Short, high-intensity runs to boost speed and endurance. Very high intensity, usually 88%-92% of max heart rate.
R (Repetition Run): Long, high-intensity runs to improve endurance and speed. Extremely high intensity, typically 92%-98% of max heart rate.

Training Goals and Intensity
Each training phase has specific goals and intensity levels:

E: Enhances basic aerobic capacity, ideal for recovery and long-distance training.
M: Adapts to race pace, builds endurance.
T: Raises lactate threshold, improves endurance.
I: Increases speed and endurance, suitable for short sprints.
R: Boosts endurance and speed, for long, intense sessions.

Case Study: I once coached a student who started with E and M training, gradually incorporating T and I, eventually achieving her personal best in a half marathon.
Adjusting Training Intensity
Adjusting training intensity based on your fitness level is crucial. Here are some suggestions:

Beginners: Focus on E and M, gradually introducing T and I.
Intermediate Runners: Balance E, M, T, and I, with occasional R training.
Advanced Runners: Increase the proportion of R training while maintaining the quality of E and M.

Reflection Question: How intense is your current training? Do you feel the need to adjust?
Third Section: Executing Training on a Treadmill
Simulating E Training
E training on a treadmill is straightforward. Set a comfortable pace, usually 60%-70% of your max heart rate, and maintain a relaxed stride for 30-60 minutes. You can watch TV or listen to music to keep entertained while keeping your heart rate in the target zone.
Note: Don't focus too much on speed; keep the pace easy to avoid injury.
Simulating M Training
For M training, set the treadmill to your target half marathon pace and run for 20-30 minutes. Adjust the incline every 5 minutes to simulate race conditions.
Case Study: One of my students improved his half marathon pace from 6:30 to 6:00 per mile through treadmill M training.
Simulating T Training
T training requires higher intensity. Set the treadmill speed to 80%-88% of your max heart rate and run for 10-20 minutes. Adjust the incline every 2-3 minutes to mimic the changes in pace.
Note: Pay attention to your body's response to avoid overexertion.
Simulating I and R Training
I and R training involve high-intensity short sprints. Set the treadmill speed to 88%-98% of your max heart rate for short distances (200-800 meters), with recovery periods in between.
Case Study: When I do I training on the treadmill, I set the speed to 7.5 mph for 400 meters, then recover for 2 minutes before repeating.
Reflection Question: Have you tried high-intensity training on a treadmill? What insights have you gained?
Fourth Section: 12-Week Training Plan
Training Calendar
Here's a 12-week training calendar for your reference:

Weeks 1-4: Focus on E and M training, increasing weekly volume by 10%.
Weeks 5-8: Increase the proportion of T training, introduce some I training.
Weeks 9-12: Emphasize M and T training, incorporate R training, reduce E training.

Note: Ensure at least one complete rest day per week to avoid overtraining.
