Past Participle of Run: Meaning and Examples
The past participle of run is run. Unlike many irregular verbs, run does not change its form between the base verb and the past participle. You say run for the present tense, ran for the simple past tense, and run for the past participle. This means that in perfect tenses and passive structures, you will use run with a helping verb such as have, has, had, or be. For example, She has run three miles today or The race was run in record time. This guide explains exactly when and how to use the past participle of run, with clear examples, common mistakes, and practical practice.
Quick Answer: Past Participle of Run
The past participle of run is run. Use it with helping verbs like have, has, had, or was/were.
- Present perfect: I have run every morning this week.
- Past perfect: She had run five kilometers before breakfast.
- Passive voice: The marathon was run in under three hours.
Understanding the Verb Forms of Run
To use the past participle correctly, it helps to see all three principal parts of the verb run:
| Base Form | Simple Past | Past Participle |
|---|---|---|
| run | ran | run |
Notice that the simple past (ran) is different from the past participle (run). This is a common point of confusion. For example, you would say Yesterday I ran to the store (simple past), but I have run to the store many times (past participle with have).
When to Use the Past Participle of Run
The past participle run appears in three main grammatical contexts:
1. Present Perfect Tense
Use have or has + run to describe an action that started in the past and continues to the present, or a past action with relevance now.
- Example: They have run this business for ten years.
- Example: He has run in every local race since 2020.
2. Past Perfect Tense
Use had + run to describe an action completed before another past action.
- Example: By the time we arrived, the engine had run out of fuel.
- Example: She had run the report twice before the meeting.
3. Passive Voice
Use a form of be + run when the subject receives the action.
- Example: The program was run by a small team.
- Example: The tests are run every morning.
Comparison: Run vs. Ran vs. Run (Past Participle)
| Form | Use | Example |
|---|---|---|

| ran (simple past) | Completed action in the past | She ran home yesterday. |
| run (past participle) | With helping verbs in perfect tenses or passive voice | He has run a marathon. / The race was run well. |

Common Mistakes with the Past Participle of Run
Even advanced learners sometimes mix up ran and run. Here are the most frequent errors:
Mistake 1: Using ran with have/has/had
Incorrect: She has ran five kilometers.
Correct: She has run five kilometers.
Why: After have, has, or had, you must use the past participle, not the simple past.
Mistake 2: Using run as the simple past
Incorrect: Yesterday I run to the store.
Correct: Yesterday I ran to the store.
Why: For a completed action in the past without a helping verb, use ran.
Mistake 3: Forgetting the helping verb in passive voice
Incorrect: The race run in the morning.
Correct: The race was run in the morning.
Why: Passive voice requires a form of be before the past participle.
Better Alternatives and When to Use Them
While run is the correct past participle, sometimes other verbs can express the idea more precisely depending on context:
- Operated – Use in formal or technical writing when referring to machines or systems: The software was operated by a technician.
- Managed – Use for businesses or teams: The department was managed by a director.
- Conducted – Use for experiments, surveys, or studies: The survey was conducted last month.
- Completed – Use when focusing on finishing a distance or task: The race was completed in record time.
Choose run when you want a direct, everyday word. Choose an alternative when you need a more specific or formal tone.
Formal vs. Informal Tone
The past participle run works in both formal and informal English, but the surrounding words change the tone:
- Informal: “I have run out of ideas.” (common in conversation)
- Formal: “The analysis has run its course.” (common in reports)
- Email context: “The system has run without errors since the update.” (neutral, professional)
In very formal writing, you might replace run with a more specific verb like executed or administered, but run itself is never incorrect.
