Struggling with the past forms of run? You’re not alone. Whether you’re drafting an email, writing an essay, or chatting with a native speaker, choosing between ran and run can be confusing. This guide will clear it all up, once and for all.
Let’s explore how run changes in the past tense and the past participle, and how to use it correctly in every situation.
The Three Forms of “Run” Explained
English verbs typically have three core forms: the base form, the simple past, and the past participle. For the irregular verb run, those forms are:
| Verb Form | Word | Example |
|---|---|---|
| Base Form | run | I run every morning. |
| Simple Past | ran | I ran to the store yesterday. |
| Past Participle | run | I have run five miles today. |

This irregular pattern is what confuses so many English learners.

Understanding the Simple Past of Run: “Ran”
The simple past of run is ran. It’s used to describe actions that were completed in the past, without any connection to the present.
Usage Examples of Past Tense Run:
- I ran across the street before the light turned red.
- She ran a marathon last month.
- They ran late for the meeting.
Notice that the verb ran stands on its own — no helping verbs like have or had are involved.
When to Use “Ran”:
- Events that happened and finished in the past.
- No reference to the present moment.
“She ran through the rain” is correct. “She has ran through the rain” is not.
Past Participle of Run: When and Why to Use “Run”
The past participle of run is also run. It’s used in perfect tenses, usually with auxiliary verbs such as has, have, had, or will have.
Present Perfect Tense with Run:
Used when an action happened at an unspecified time before now.
- I have run three miles this morning.
- She has run a successful business for years.
Past Perfect Tense:

Remember: In perfect tenses, run always pairs with an auxiliary verb.
Have Run vs Have Ran: Clear Up the Confusion
Let’s set the record straight:
- ✅ Correct: I have run
- ❌ Incorrect: I have ran
Why?
The verb have requires a past participle, and ran is the simple past — not the participle.
| Phrase | Correct? | Explanation |
|---|---|---|
| I have ran | ❌ | “Ran” is not a past participle |
| I have run | ✅ | “Run” is the correct past participle form |
| She had ran | ❌ | Wrong use of simple past with past perfect |
| She had run | ✅ | Correct auxiliary + past participle |
Rule of Thumb: Use run with have, has, had, will have.
Common Mistakes with the Verb “Run”
Even native speakers mix this up. Here are the most common errors:
1: Using “ran” with auxiliary verbs
- ❌ I had ran out of ideas.
- ✅ I had run out of ideas.
2: Confusing base and past forms
- ❌ I run to the market yesterday.
- ✅ I ran to the market yesterday.
3: Saying “have ran”
- ❌ They have ran this place before.
- ✅ They have run this place before.
Subject-Verb Agreement in Past Tense with “Run”
In the past tense, subject-verb agreement is simpler because the verb form ran doesn’t change:
- I ran
- You ran
- He/She/It ran
- We ran
- They ran
In perfect tenses, make sure the helping verb agrees with the subject:
- He has run
- They have run
Tip: Don’t let the auxiliary verb trip you up — it’s the one that changes, not run.
