Workout Execution Tips
For VO2 Max Intervals
- Warm up properly: 15 min easy + strides
- Start conservatively: First rep should feel controlled
- Even splits: Aim for consistent pace across reps
- Full recovery: Wait until heart rate drops below 70% max
- Quality over quantity: Stop if form breaks down
For Tempo Runs
- "Comfortably hard": You can speak in short phrases
- Consistent pace: Don't speed up or slow down
- Include warm-up/cool-down: 10 min each side
For Easy Runs
- Truly easy: Conversational pace
- Heart rate: Below 75% of max
- Purpose: Recovery and aerobic base
Recovery and Adaptation
Sleep Requirements
| Training Phase | Minimum Sleep |
|---|---|
| Weeks 1-2 | 7-8 hours |
| Weeks 3-6 | 8-9 hours |
| Weeks 7-8 | 7-8 hours |
Nutrition Focus
- Post-workout: Carbs + protein within 30 min
- Daily protein: 1.4-1.6 g/kg body weight
- Hydration: Pale yellow urine as target
Warning Signs to Watch
Reduce training if you experience:
- Persistent fatigue not relieved by rest
- Elevated resting heart rate (5+ bpm above normal)
- Poor sleep quality
- Unusual muscle soreness
- Loss of motivation
Modifications
If You're Struggling
| Problem | Solution |
|---|---|
| Can't hit paces | Slow down 5-10 sec/km |
| Too tired for workouts | Add an extra rest day |
| Lingering soreness | Replace VO2 work with easy running |
| Time constraints | Prioritize VO2 session, shorten others |
If It Feels Too Easy
| Situation | Adjustment |
|---|---|
| Finishing intervals feeling fresh | Add 1-2 reps |
| Recovery feels too long | Cut recovery by 15-30 sec |
| Easy days feel too easy | Good! Keep them easy |
