Zone 2 heart rate for a 50-year-old
For a 50-year-old, Zone 2 heart rate is roughly 102–119 bpm, based on an estimated max heart rate of 170 bpm. If you know your resting heart rate, the Karvonen table below gives a more personal range.
All 5 heart rate zones at age 50
| Zone | 220 − age (max 170) | Tanaka formula (max 173) |
|---|---|---|
| Zone 1 · Recovery | 85–102 bpm | 86–104 bpm |
| Zone 2 · Easy aerobic | 102–119 bpm | 104–121 bpm |
| Zone 3 · Tempo | 119–136 bpm | 121–138 bpm |
| Zone 4 · Threshold | 136–153 bpm | 138–156 bpm |
| Zone 5 · Max | 153–170 bpm | 156–173 bpm |
Two common max heart rate estimates: 220 minus age, and the Tanaka formula (208 − 0.7 × age). Real max heart rate can differ from both by 10–15 bpm.
Zone 2 at age 50 by resting heart rate
The Karvonen method uses your heart rate reserve (max minus resting), so fitter people with lower resting heart rates get a range that fits them better. Zone 2 = resting + 60–70% of reserve.
| Resting heart rate | Zone 2 (Karvonen) |
|---|---|
| 50 bpm | 122–134 bpm |
| 55 bpm | 124–136 bpm |
| 60 bpm | 126–137 bpm |
| 65 bpm | 128–138 bpm |
| 70 bpm | 130–140 bpm |
| 75 bpm | 132–142 bpm |

- Talk test: full sentences means you're in Zone 2.
- Expect to slow down: many runners need to run 1–2 minutes per mile slower at first.
- Track progress: your pace at the same heart rate should improve over 4–8 weeks. How long Zone 2 takes.

What is Zone 2 heart rate for a 50-year-old?
Using the common 220-minus-age estimate, max heart rate is about 170 bpm, so Zone 2 (60–70% of max) is about 102–119 bpm. Adding your resting heart rate gives a more personal range.
Is 119 bpm too high for Zone 2 at 50?
Not necessarily. 119 bpm is the top of the estimated range for age 50. Max heart rate varies by 10–15 bpm between people, so use the talk test as a check: if you can speak in full sentences, you're close to Zone 2.
How do I find my exact Zone 2?
Add your resting heart rate to the Zone 2 calculator (Karvonen method), or get a lab test. The talk test is a good free cross-check.
