What Is the Past Tense of Run?
The past tense of run is ran. This is an irregular verb, so it does not follow the standard pattern of adding -ed. You say I run in the present, I ran in the past simple, and I have run with the past participle. The past participle form is also run, which is different from the past tense. This guide explains the forms, shows you how to use them naturally, and helps you avoid common mistakes.
Quick Answer: Past Tense of Run
| Form | Example |
|---|---|
| Base form (present) | run |
| Past simple | ran |
| Past participle | run |
| Present participle / gerund | running |
| Third person singular (present) | runs |
Use ran for completed actions in the past. Use run (past participle) with auxiliary verbs like have, has, had, is, was, or were.
When to Use Ran vs. Run
This is the most common point of confusion. The rule is simple:
- Ran = past simple (no auxiliary verb). Example: She ran to the bus stop yesterday.
- Run = past participle (used with have, has, had, or be verbs). Example: She has run three miles today.
If you are writing a simple past sentence, always use ran. If you are using a perfect tense or passive voice, use run.
Formal vs. Informal Use
In formal writing, such as business emails or academic reports, you will use both forms correctly depending on the tense. For example:
- Formal (past simple): The project ran from January to March.
- Formal (present perfect): The team has run several tests this quarter.
In informal conversation, the same rules apply, but speakers sometimes make errors. You might hear someone say, I run to the store yesterday (incorrect) or I have ran that race before (incorrect). Stick to the correct forms to sound clear and educated.

Common Mistakes with Run and Ran
Even advanced learners sometimes mix these up. Here are the most frequent errors and how to fix them.
Mistake 1: Using “run” as the past simple
Incorrect: Yesterday, I run to the store.
Correct: Yesterday, I ran to the store.
Why: Run is the present tense form. For a completed action in the past, you need ran.
Mistake 2: Using “ran” with “have” or “has”
Incorrect: She has ran that company for years.
Correct: She has run that company for years.
Why: After has, have, or had, you must use the past participle, which is run.
Mistake 3: Confusing “run” with “ran” in passive sentences
Incorrect: The program was ran by volunteers.
Correct: The program was run by volunteers.
Why: The passive voice uses the past participle (run), not the past simple (ran).
Mistake 4: Using “ran” in perfect tenses
Incorrect: I had ran three miles before breakfast.
Correct: I had run three miles before breakfast.
Why: The past perfect always uses the past participle.
