When you hear phrases like “has run” and “has ran,” it is easy to understand why they get mixed up. Both run and ran are forms of the same irregular verb, but they do not work in the same grammatical situations. The difference becomes especially important when you use helping verbs such as has, have, or had.
The good news is that the rule is straightforward once you understand the three principal forms of run: run (base form), ran (simple past), and run (past participle). Because has must be followed by a past participle, “has run” is the grammatically correct form in standard English. “Has ran” is a common mistake, although you may hear it in informal speech or certain regional varieties of English.
Quick Answer
“Has run” is correct; “has ran” is incorrect in standard English. Use has run because run is the past participle of run. Ran is the simple past form and normally cannot follow has, have, or had.
Why People Confuse It
The confusion comes from the fact that run is an irregular verb with two identical forms:
- Base form: run
- Simple past: ran
- Past participle: run
Compare these sentences:
- She ran five miles yesterday.
- She has run five miles today.
The first sentence uses ran because it describes a completed action in the simple past.
The second uses has run because has requires the past participle.
This is the key distinction behind has run vs. has ran.
First Word: Has Run
Has run is the correct construction in standard English.
It uses:
has + past participle
Since run is the past participle of the verb run, we say:
He has run three miles this morning.
The present perfect tense is commonly formed with has/have + past participle.
Examples of “Has Run”
- She has run every morning this week.
- The machine has run continuously for six hours.
- He has run out of money.
- The dog has run away.
- The program has run successfully.
- The athlete has run faster than expected.
Notice that run remains the same as the base form, even though it is functioning as a past participle.
Second Word: Has Ran
Has ran is not considered correct in standard English.
The problem is that ran is the simple past form, not the past participle.
We can use ran by itself:
She ran to the store.
But we cannot normally place it after has:
❌ She has ran to the store.
The standard form is:
âś… She has run to the store.
This mistake is particularly common because ran sounds natural when describing something that happened in the past.

| Form | Grammatical Role | Example | Correct? |
| run | Base form | I run every day. | âś… |
| ran | Simple past | I ran yesterday. | âś… |
| run | Past participle | I have run today. | âś… |
| has run | Present perfect | She has run five miles. | âś… |
| has ran | Incorrect standard construction | She has ran five miles. | ❌ |
| had run | Past perfect | She had run before breakfast. | âś… |
The Basic Pattern
Remember:
Present: I run.
Past: I ran.
Past participle: I have run.
That one pattern solves most has run vs. has ran questions.
When to Use Each
Use “Has Run”
Use has run when run follows has as part of the present perfect tense.
Examples:
- Maria has run five kilometers.
- The engine has run all night.
- The company has run several successful campaigns.
It can also appear in expressions such as:
- has run out
- has run away
- has run into
- has run across
- has run for office
For example:
The store has run out of milk.
Use “Ran”
Use ran when talking about a completed action in the simple past.
Examples:
- I ran yesterday.
- She ran home after school.
- They ran a marathon last year.
- He ran into an old friend.
A useful clue is that ran often appears with a specific past-time expression:
- yesterday
- last week
- last year
- two hours ago
- in 2024
For example:
She ran five miles yesterday.
But:
She has run five miles this week.

Common Mistakes
1. Using “Ran” After “Has”
The most common error is:
❌ He has ran five miles.
Correct it to:
âś… He has run five miles.
2. Thinking “Ran” Is the Past Participle
It isn’t. The forms are:
run → ran → run
The middle form, ran, is the simple past.
3. Using “Run” for Simple Past
Another common mistake is:
❌ She run yesterday.
The correct sentence is:
âś… She ran yesterday.
4. Confusing “Has Run” With “Ran”
The tense determines which form you need:
She ran yesterday.
She has run every day this week.
The first is simple past. The second is present perfect.
Memory Trick
Here’s an easy way to remember it:
Ran stands alone; run needs a helper.
- I ran.
- She ran.
- He ran.
But:
- I have run.
- She has run.
- He has run.
- They had run.
Think of the pattern:
run → ran → run
If you see has, have, or had, choose run, not ran.
American vs. British English
There is no standard American-versus-British difference that makes “has ran” correct in one variety and “has run” correct in the other.
Both American and British standard English use:
has run
and:
ran
for the simple past.
You may hear “has ran” in some informal, regional, or nonstandard speech communities, but it is not the standard form you should use in formal writing, academic English, professional communication, or carefully edited content.
