Common Mistakes with the Verb ‘run’
The verb ‘run’ is one of the most frequently used irregular verbs in English, but it is also one of the most commonly misused. The core problem is that ‘run’ has three distinct forms—run (present), ran (past), and run (past participle)—and many learners confuse the past tense ‘ran’ with the past participle ‘run’. This guide directly explains the correct forms, shows you how to avoid the most frequent errors, and gives you practical examples for real writing and conversation.
Quick Answer: The Three Forms of ‘run’
To use ‘run’ correctly, you need to know its three principal parts:
- Base form (present tense): run (e.g., “I run every morning.”)
- Past tense: ran (e.g., “She ran to the bus stop yesterday.”)
- Past participle: run (e.g., “He has run five kilometers today.”)
The most common mistake is using ‘ran’ where the past participle ‘run’ is required, especially after auxiliary verbs like ‘have’, ‘has’, ‘had’, ‘be’, or ‘been’.
Understanding the Forms: A Comparison Table
| Tense / Structure | Correct Form | Example | Common Mistake |
|---|---|---|---|
| Simple Present | run / runs | They run a small business. | They runs a small business. (subject-verb agreement error) |
| Simple Past | ran | I ran out of time. | I run out of time yesterday. (using present for past) |
| Present Perfect | have/has + run | She has run the marathon twice. | She has ran the marathon twice. (using past tense with ‘has’) |
| Past Perfect | had + run | By noon, he had run all the errands. | By noon, he had ran all the errands. |
| Passive Voice | be + run | The program is run by volunteers. | The program is ran by volunteers. |
| Conditional Perfect | would have + run | I would have run faster if I had trained. | I would have ran faster if I had trained. |
Natural Examples in Context
Here are examples that show how ‘run’ is used naturally in everyday conversation, email, and writing. Pay attention to the form and the context.
Everyday Conversation (Informal)
- “I ran into an old friend at the grocery store.” (simple past, chance meeting)
- “We’ve run out of milk. Can you pick some up?” (present perfect, current result)
- “The kids ran around the park until they were tired.” (simple past, completed action)
- “My phone battery has run down again.” (present perfect, current state)
Email and Professional Writing (Formal)
- “The meeting ran over by fifteen minutes.” (simple past, neutral report)
- “The project has run into unexpected delays.” (present perfect, ongoing situation)
- “All reports are run through a quality check before submission.” (passive, present tense)
- “If the test had run successfully, we would have launched last week.” (past perfect conditional)
Nuance and Tone
In informal conversation, ‘run’ is often used in phrasal verbs like ‘run into’ (meet unexpectedly), ‘run out of’ (exhaust supply), or ‘run over’ (exceed time). In formal writing, the same phrasal verbs are acceptable but should be used with precise context. For example, “The budget has run over by 10%” is fine in a business email, but “The budget ran over” is more direct and slightly less formal.
Common Mistakes with ‘run’
Below are the four most frequent errors learners make. Each mistake is followed by the correction and an explanation.
Mistake 1: Using ‘ran’ after ‘have’, ‘has’, or ‘had’
Incorrect: “She has ran three miles already.”
Correct: “She has run three miles already.”
Why: After any form of ‘have’ (have, has, had), you must use the past participle, which is ‘run’, not the past tense ‘ran’.
Mistake 2: Using ‘run’ for simple past
Incorrect: “Yesterday, I run to the store.”
Correct: “Yesterday, I ran to the store.”
Why: For a completed action in the past, use the simple past form ‘ran’.
Mistake 3: Using ‘ran’ in passive voice
Incorrect: “The event was ran by a small team.”
Correct: “The event was run by a small team.”
Why: In passive voice, the past participle is required. ‘Was’ + ‘ran’ is always wrong.
Mistake 4: Confusing ‘run’ with ‘ran’ in conditional sentences
Incorrect: “If I had ran faster, I would have won.”
Correct: “If I had run faster, I would have won.”
Why: The past perfect (had + past participle) needs ‘run’, not ‘ran’.
Better Alternatives and When to Use Them
Sometimes ‘run’ is not the best verb for the situation. Here are more precise alternatives depending on context.
- Instead of “run a business”: Use “manage a business” or “operate a business” for a more professional tone in formal writing.
- Instead of “run away”: Use “flee” or “escape” in serious or dramatic contexts.
- Instead of “run a test”: Use “conduct a test” or “perform a test” in technical or academic writing.
- Instead of “run late”: Use “be delayed” or “be behind schedule” in formal emails.
When to use ‘run’: ‘Run’ is best for everyday speech, informal writing, and phrasal verbs. It is also the correct choice in idiomatic expressions like “run the risk” or “run the show.”

Frequently Asked Questions
1. Is it “I have ran” or “I have run”?
It is always “I have run.” ‘Have’ requires the past participle form, which is ‘run’. ‘Ran’ is only used for the simple past tense without an auxiliary verb.
2. Can I use “ran” after “was” or “were”?
No. After any form of ‘be’ (am, is, are, was, were, been), you must use the past participle ‘run’ for passive voice. For example: “The race was run in record time.”
3. What is the difference between “run” and “ran” in a sentence?
‘Run’ is the base form and past participle; ‘ran’ is the simple past. Use ‘ran’ for a single completed action in the past (e.g., “He ran home”). Use ‘run’ with auxiliary verbs (e.g., “He has run home”) or in the present tense (e.g., “They run every day”).
4. Is “run” an irregular verb?
Yes, ‘run’ is an irregular verb. Its forms do not follow the regular -ed pattern. The three forms are run (present), ran (past), and run (past participle). For more on irregular verb patterns, see our Verb Forms Explained section.
Final Tips for Using ‘run’ Correctly
To master ‘run’, practice these two rules:
- Rule 1: If you see ‘have’, ‘has’, ‘had’, ‘be’, ‘been’, or ‘being’ nearby, use ‘run’ (the past participle).
- Rule 2: If you are talking about a finished action in the past with no auxiliary verb, use ‘ran’.
