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 form is not “runned” but ran, and its past participle is run. Many learners mistakenly treat it as a regular verb or mix up the forms in different tenses. This guide directly explains the correct forms of run, shows you the most common errors, and gives you clear examples for real writing and conversation.
Quick Answer: The Three Forms of ‘run’
Here are the three principal parts of the verb run:
- Base form: run (used for present tense, except third person singular)
- Past tense: ran (used for simple past actions)
- Past participle: run (used with auxiliary verbs like have, has, had, or in passive voice)
Example: “I run every morning.” (present) / “Yesterday, I ran five miles.” (past) / “I have run three marathons.” (past participle)
Why Learners Make Mistakes with ‘run’
The main reason for errors is that run looks like a regular verb (it doesn’t change spelling in the base form), so learners naturally add -ed to form the past tense. Another source of confusion is that the past participle is identical to the base form, which is unusual. In contrast, verbs like walk become walked in both past and past participle, so the pattern for run feels inconsistent.
Comparison Table: ‘run’ vs. Common Irregular Verbs
| Verb | Base Form | Past Tense | Past Participle |
|---|---|---|---|
| run | run | ran | run |
| come | come | came | come |
| swim | swim | swam | swum |
| sing | sing | sang | sung |
| begin | begin | began | begun |
Notice that run and come share the same pattern: the past participle equals the base form. This is a small group of verbs, so it helps to memorize them together.
Natural Examples of ‘run’ in Context
Everyday Conversation
- “I run late every morning because I hit snooze.” (present habit)
- “She ran to the bus stop but missed it.” (past action)
- “We have run out of milk. Can you buy some?” (present perfect)
Email and Writing
- “The project ran from January to March.” (simple past, formal tone)
- “The system has run without errors since the update.” (present perfect, technical context)
- “Please let me know if the meeting runs over time.” (present tense, polite request)
Formal vs. Informal Nuance
In informal conversation, you might hear: “I ran into an old friend yesterday.” In formal writing, you would say: “I encountered a former colleague.” The verb run itself is neutral, but the phrasal verb run into is more casual. For business emails, use run directly: “The test ran successfully.” Avoid “The test was ran” (incorrect) or “The test has been run” (correct).
Common Mistakes with ‘run’
Mistake 1: Using “runned” for past tense
Incorrect: “He runned a marathon last weekend.”
Correct: “He ran a marathon last weekend.”
Why it happens: Learners apply the regular -ed rule. This is the most frequent error.
Mistake 2: Using “ran” as a past participle
Incorrect: “I have ran five kilometers today.”
Correct: “I have run five kilometers today.”
Why it happens: The past tense ran sounds natural, but after have, has, or had, you must use the past participle run.
Mistake 3: Confusing “run” with “ran” in present perfect
Incorrect: “She has ran away from home.”
Correct: “She has run away from home.”
Tip: Remember the pattern: have/has/had + run (not ran).
Mistake 4: Using “run” for past tense in narratives
Incorrect: “Yesterday, I run to the store.”
Correct: “Yesterday, I ran to the store.”
Why it happens: In fast speech, the present form slips in. Always check the time marker (yesterday, last week, ago) to choose ran.
Better Alternatives and When to Use Them
Sometimes run is not the best word choice. Here are alternatives for different contexts:
- Jog – Use for slower, steady running. “I jog every evening.” (less intense than run)
- Sprint – Use for short, fast running. “He sprinted to the finish line.” (emphasizes speed)
- Dash – Use for quick, urgent running. “She dashed into the office.” (informal, implies hurry)
- Operate – Use for machines or systems. “The software operates smoothly.” (formal, technical)
- Manage – Use for running a business or team. “She manages the department.” (professional tone)
When to use run: It is the most common and versatile word for physical movement, machine operation, and managing activities. Use it in everyday speech, emails, and general writing. Choose alternatives when you need a more specific or formal tone.

Final Tips for Using ‘run’ Correctly
To avoid mistakes with run, focus on the time of the action. If the action happened and finished in the past, use ran. If the action connects to the present (with have, has, or had), use run. Practice by writing three sentences each day: one present, one past, and one present perfect.
