Understanding How “Run” Changes in the Past and Past Participle

The English language can be tricky, especially when it comes to irregular verbs like “run”. You might wonder why the past tense and past participle forms of “run” don’t follow the simple patterns of regular verbs. Instead of just adding “ed” to make it “runned,” the verb changes its form.

In this guide, we will take a deep dive into the past and past participle of run, clarify common mistakes, and provide plenty of examples so you can master using “run” in different contexts.

What is the Past Tense of “Run”?

When we talk about the past tense of run, we are referring to the form of the verb used to describe an action that has already happened. Unlike regular verbs, where we simply add -ed (e.g., “talk” becomes “talked”), the verb “run” is irregular, meaning it changes its form completely.

The simple past tense of run is “ran.” For instance:

• I ran to the store yesterday.
• She ran five miles last night.

In these examples, the action of running has already been completed in the past, and so we use ran. It’s important to remember that “ran” is the past form of “run”, not “runed” or anything else. Irregular verbs like this require memorization and practice to avoid confusion.

Examples of “Ran” in the Past Tense

To make the concept clearer, let’s go through a variety of examples where “ran” is used correctly in the past tense.

• They ran to catch the bus.
• We ran out of time during the meeting.
• The dog ran across the yard.
• He ran after the ball when it rolled down the hill.

In each of these sentences, “ran” clearly indicates a past action. Notice how the verb doesn’t change regardless of the subject (I, we, they, he, etc.). This consistency is one thing that makes irregular verbs easier to use once you know their forms.

Common Mistakes in Using “Ran”

Many English learners confuse the past tense of “run” with the past participle, leading to errors like, “I have ran” or “She has ran”. In fact, this is incorrect, as “ran” is only used in the simple past tense, not with auxiliary verbs like “have” or “has.” For example:

• Incorrect: I have ran a marathon.
• Correct: I have run a marathon.

This distinction brings us to the next important form: the past participle of “run”.

What is the Past Participle of “Run”?

The past participle form of a verb is used in perfect tenses, which describe actions that have been completed at some point in time before now. For regular verbs, the past participle often looks just like the past tense. For irregular verbs like “run,” however, it follows a unique pattern.

The past participle of run is “run.” Yes, you read that right. Unlike the past tense form (ran), the past participle remains “run.”

Here’s how you would use it:

• I have run five miles today.
• She has run to the store.
• They have run this company for 20 years.

As you can see, the past participle “run” is paired with auxiliary verbs like “have” and “has” to form the present perfect tense. “Ran” cannot be used in this context—this is a mistake many learners make.

Examples of “Run” in the Past Participle Tense

Now, let’s explore more examples to see how run functions in the past participle tense:

Example	Explanation
I have run five marathons.	Describes an action completed before now using “have” + “run.”
She had run out of ideas.	Refers to a completed action in the past perfect tense.
They have run this project for months.	Ongoing or recently completed action.
By tomorrow, we will have run a total of ten miles.	Future perfect tense using “will have” + “run.”

Common Mistakes with the Past Participle of “Run”

One of the most common errors is using “ran” instead of “run” in the perfect tenses. As mentioned earlier, the correct form when using “have” or “has” (or any other auxiliary verb) is always “run”:

• Incorrect: I had ran a mile before the rain started.
• Correct: I had run a mile before the rain started.

The difference may seem small, but it’s essential for proper grammar.

Using “Run” in Different Tenses

To fully grasp the verb “run,” it’s essential to understand how it behaves in various tenses. This is where many learners struggle because irregular verbs like “run” do not follow standard conjugation patterns. Below is a breakdown of how to use “run” across different tenses.

Present Tense for “Run”

The present tense for run uses the base form “run” and applies to actions happening now or regularly. For example:

• I run every morning.
• They run three times a week.
• She runs quickly. (Note that in the third person singular, we add an “s.”)

Present Continuous Tense

When describing actions that are happening right now, we use the present continuous tense with the gerund form, “running.”

• I am running to the store.
• He is running late.
• They are running a race.

The present continuous tense helps describe an action in progress at the moment of speaking.

Simple Past Tense of “Run”

As we’ve covered, the simple past tense run is “ran.” It describes actions completed in the past:

• He ran yesterday.
• I ran the marathon last week.

Past Perfect Tense of “Run”

The past perfect of run describes an action that was completed before another past action. This tense always uses the past participle “run” and the auxiliary verb “had.”

• By the time she arrived, I had run to the store.
• They had run all the way home before realizing they forgot the keys.

In both examples, the action of running was finished before another past event.

Future Tense of “Run”

To describe actions that will happen in the future, we use “will run”:

• I will run a 5K next month.
• We will run the experiment tomorrow.

Future Perfect Tense

The future perfect tense describes an action that will be completed before a specific future time. It uses “will have run”:

• By next week, I will have run 20 miles.
• They will have run out of supplies by the end of the day.

Here, the future perfect tense indicates that the action of running will be completed by a specific future point.
