Common Mistakes with the Verb ‘run’
The verb “run” is one of the most frequently used irregular verbs in English, and it causes confusion because its past tense and past participle forms are identical: “ran” (past tense) and “run” (past participle). The most common mistake is using “ran” where the past participle “run” is required, especially after auxiliary verbs like “have,” “has,” or “had.” For example, saying “I have ran five miles” is incorrect; the correct form is “I have run five miles.” This guide will help you master the correct forms of “run” and avoid the errors that trip up even advanced learners.
Quick Answer: The Forms of ‘run’
- Base form: run (used for present tense, except third-person singular)
- Third-person singular: runs (he/she/it runs)
- Past tense: ran (used for completed actions in the past)
- Past participle: run (used with auxiliary verbs like have, has, had, be, get)
- Present participle/gerund: running
The key rule: after any form of “have” (have, has, had) or “be” (am, is, are, was, were), always use the past participle “run,” never “ran.”

Common Mistakes with ‘run’
Here are the most frequent errors learners make, along with explanations and corrections.
Mistake 1: Using “ran” after “have,” “has,” or “had”
Incorrect: I have ran three miles today.
Correct: I have run three miles today.
Why: After any form of “have,” you must use the past participle, which is “run,” not the past tense “ran.”
Mistake 2: Using “run” as the simple past tense
Incorrect: Yesterday, I run to the store.
Correct: Yesterday, I ran to the store.
Why: For a completed action in the past without an auxiliary verb, use the past tense “ran.”
Mistake 3: Confusing “run” with “ran” in passive voice
Incorrect: The event was ran by a local charity.
Correct: The event was run by a local charity.
Why: Passive voice requires the past participle “run” after the verb “be.”
Mistake 4: Using “ran” in perfect conditional sentences
Incorrect: If I had known, I would have ran faster.
Correct: If I had known, I would have run faster.
Why: The conditional perfect uses “would have” + past participle, so “run” is correct.
