Training Zones
Heart Rate Zone System
| Zone | Name | % Max HR | Perceived Effort | Purpose |
|---|---|---|---|---|
| 1 | Recovery | 50-60% | Very easy, conversational | Active recovery |
| 2 | Easy/Aerobic | 60-70% | Easy, can hold full conversation | Base building, fat oxidation |
| 3 | Tempo | 70-80% | Comfortably hard, short sentences | Lactate threshold improvement |
| 4 | Threshold | 80-90% | Hard, few words at a time | VO2max improvement |
| 5 | Interval/Max | 90-100% | All-out, cannot speak | Speed and power |
Estimating Max Heart Rate
Formula 1 (Traditional): 220 - Age = Estimated Max HR
Formula 2 (Tanaka): 208 - (0.7 x Age) = Estimated Max HR
Example (Age 35):
Traditional: 220 - 35 = 185 bpm
Tanaka: 208 - (0.7 x 35) = 183.5 bpm
Zone Calculation (using 185 max HR):
Zone 1: 93-111 bpm
Zone 2: 111-130 bpm
Zone 3: 130-148 bpm
Zone 4: 148-167 bpm
Zone 5: 167-185 bpm

Pacing Strategies
Race Pace Calculator (Based on Recent Race Time)
If your 5K time is: [TIME]
Estimated 10K: 5K time x 2.09
Estimated Half Marathon: 5K time x 4.65
Estimated Marathon: 5K time x 9.8
Example (5K in 25:00):
10K: ~52:15
Half Marathon: ~1:56:15
Marathon: ~4:05:00
Pacing Strategy by Race
| Race | Strategy | Details |
|---|---|---|
| 5K | Even or slight negative split | Start controlled, push last mile |
| 10K | Even splits | Consistent pace throughout |
| Half Marathon | Slight negative split | First half 10-15 sec/mi slower than goal |
| Marathon | Conservative start | First 10K at goal+15 sec/mi, settle into pace, push last 10K |
Treadmill Pace Conversion
