Can I Break The 10% Rule? | GTN Coaches Corner

Summary and Key Topics

This video is part of GTN's (Global Triathlon Network) "Coaches Corner" series, where coaches answer viewer questions on various triathlon training topics. This episode focuses on the "10% Rule" and covers fueling during training, whether to wear socks, commute cycling as training, scheduling back-to-back sessions, and injury prevention for beginner runners.

1. Should You Fuel During Low-Intensity Workouts?

  • Question: "Do I need to fuel during a 1.5 to 2-hour Zone 2 (low-intensity) run?"
  • Answer Summary:
    • Fueling during low-intensity workouts isn't mandatory, but for sessions longer than 1.5 hours, it's beneficial.
    • Reasons:
      1. Fueling during exercise lets you start recovery sooner. It shortens glycogen replenishment time, letting you prepare for the next workout faster.
      2. Practicing fueling during training helps develop your race-day fueling ability.
    • Memorable Quote:
      • "If you fuel during exercise, you can start glycogen recovery even before the workout is over."

2. Should You Train Without Socks in Triathlon?

  • Question: "I want to skip socks during T1 (swim-bike transition) and T2 (bike-run transition) to save time. Should I practice without socks?"
  • Answer Summary:
    • Going sockless can save transition time, but it's better to wear socks during training.
    • Reasons:
      1. Training without socks can cause blisters or toenail damage that disrupts training consistency.
      2. After a race, you have recovery days to manage blisters.
    • Memorable Quote:
      • "Putting on socks only takes 5-10 seconds. There's no need to risk ruining your training to save that time."

3. Can Commute Cycling Replace Training?

  • Question: "Can my daily 20-minute bike commute count as training?"
  • Answer Summary:
    • Commute cycling should be considered as part of training, but it cannot replace it.
    • Reasons:
      1. Short commute rides help with maintenance but have limited impact on fitness improvement.
      2. However, commute riding can affect fatigue and recovery, so it should be factored into your training plan.
    • Memorable Quote:
      • "Commute riding can't replace training, but it does affect fatigue and recovery, so it must be accounted for."

4. Back-to-Back Sessions: Immediately After or Split Throughout the Day?

  • Question: "Should I do workout sessions back-to-back, or split them throughout the day?"
  • Answer Summary:
    • Default Principle: Unless your coach specifically prescribes it, splitting sessions is better.
    • Reasons:
      1. Splitting sessions improves workout quality. Less fatigue means more effective training.
      2. Back-to-back sessions can increase mental and physical stress.
    • Exception:
      • Brick sessions (cycling immediately followed by running) may require consecutive sessions.
    • Memorable Quote:
      • "Splitting workouts reduces the preparation and motivation burden, making your day less stressful overall."

5. Event Planning for 70.3 Triathlon Preparation

  • Question: "I'm preparing for a 70.3 triathlon in 7 months. What events should I include?"
  • Answer Summary:
    • Set process goals (intermediate milestones) to maintain motivation and track progress.
    • Recommended events:
      1. Sprint-distance triathlon
      2. Olympic-distance triathlon
    • Caution:
      • Adding too many events can disrupt training consistency.
    • Memorable Quote:
      • "If your goal is simply to finish a 70.3, it's best to build up progressively with sprint and Olympic distances."

6. The 10% Rule and Injury Prevention for Beginner Runners

  • Question: "As a beginner runner, how do I prevent injuries? What is the 10% rule?"
  • Answer Summary:
    • The 10% Rule: Don't increase your weekly training volume (distance or intensity) by more than 10%.
    • Reasons:
      1. Cardiovascular fitness improves quickly, but bones, ligaments, and tendons take much longer to adapt.
      2. The gap in adaptation speed between cardiovascular fitness and structural tissue can lead to injury.
    • Specific Example:
      • If you ran 10km last week, don't exceed 11km this week.
      • If you're adding intensity, keep the distance the same.
    • Memorable Quotes:
      • "Cardiovascular fitness improves in 4-6 weeks, but bones and ligaments can take 12 weeks or more. This gap is what causes injuries."
      • "Following the 10% rule prevents the vicious cycle of getting injured and having to start over from scratch."

Key Terms

  • 10% Rule: Don't increase weekly training volume by more than 10%.
  • Fueling: Consider fueling even during low-intensity sessions for recovery.
  • Wearing Socks: Wear socks during training to prevent injuries.
  • Commute Cycling: Consider it part of training, but it's not a replacement.
  • Process Goals: Sprint and Olympic distance events as stepping stones for long-term goals.
  • Injury Prevention: Understand the adaptation gap between cardiovascular fitness and structural tissue, and plan training accordingly.

Closing Thoughts

This video is packed with practical and useful advice for triathlon training. It particularly emphasizes that following fundamental principles like the 10% rule prevents injuries and enables sustainable training. The coaches' friendly and detailed responses to viewer questions are also impressive.

"Good questions lead to better training. Looking forward to your next question!"
