Key Training Tips
- Block 1: Release your body, even if legs feel fresh, don't accelerate
- Blocks 2 & 3: The sweet spot for steady pace work - this is where growth happens!
- Blocks 4 & 5: If feeling good, excellent! If struggling, flow slower and control heart rate
- Between blocks: Use walks to hydrate, breathe, relax shoulders, release jaw tension
