Why run-walk intervals?
Muscles, tendons and joints need time to get used to the load. Walking breaks reduce the strain without forcing you to stop your workout. Programs like “Couch to 5K” from the UK’s National Health Service (NHS) are built on exactly this idea: week by week, the running segments get longer and the walking breaks shorter.
An example plan for eight weeks
Start and end every session with 5 minutes of brisk walking. Repeat the intervals until you reach about 20 to 30 minutes. If a week feels too hard, simply repeat it.
| Week | Run | Walk | Repeats |
|---|---|---|---|
| 1 | 1 min | 1.5 min | 8× |
| 2 | 1.5 min | 2 min | 6× |
| 3 | 3 min | 1.5 min | 5× |
| 4 | 5 min | 2.5 min | 3× |
| 5 | 8 min | 3 min | 2× |
| 6 | 10 min | 3 min | 2× |
| 7 | 25 min | – | 1× |
| 8 | 30 min | – | 1× |
How fast should I run?
Slower than you think. As a rule of thumb, you should still be able to speak in full sentences while running. Pace is secondary at the start – what matters is that you run regularly.
Common mistakes
- Starting too fast and running out of steam after a few minutes
- Running every day without rest days
- Ignoring pain – take a break if something hurts and have it checked by a doctor if in doubt
- Increasing your volume too quickly
