The honest answer depends on where you are starting. Two guides, for a runner already training consistently and for someone starting close to zero:
| Distance | Already running | Starting from scratch |
|---|---|---|
| 5K fun run | 2 to 4 weeks | 6 to 8 weeks |
| 10K | 4 to 6 weeks | 8 to 10 weeks |
| Half marathon (21.1K) | 8 to 12 weeks | 16 to 20 weeks |
Those windows assume consistent, structured training, not just logging distance. Most recreational runners improve fastest by running most of their week easy and keeping the hard days genuinely hard. If you want a plan built around your assessment and this race as the target, our personal training for runners does exactly that. You can also predict your finish time with our running pace calculator and dial in your easy pace with the heart rate zones calculator.
