+description: "Set a maximum duration for a task to run."
+---
+
+The `maxDuration` parameter sets a maximum compute time limit for tasks. When a task exceeds this duration, it will be automatically stopped. This helps prevent runaway tasks and manage compute resources effectively.
+
+You must set a default maxDuration in your `trigger.config.ts` file, which will apply to all tasks unless overridden:
+
+```ts /config/trigger.config.ts
+import { defineConfig } from "@trigger.dev/sdk";
+
+export default defineConfig({
+  project: "proj_gtcwttqhhtlasxgfuhxs",
+  maxDuration: 60, // 60 seconds or 1 minute
+});
+```
+
+<Note>
+  The minimum maxDuration is 5 seconds. If you want to avoid timeouts, set this value to a very large number of seconds.
+</Note>
+
+You can set the `maxDuration` for a run in the following ways:
+
+- Across all your tasks in the [config](/config/config-file#max-duration)
+- On a specific task
+- On a specific run when you [trigger a task](/triggering#maxduration)
+
+## How it works
+
+The `maxDuration` is set in seconds, and is compared to the CPU time elapsed since the start of a single execution (which we call [attempts](/runs#attempts)) of the task. The CPU time is the time that the task has been actively running on the CPU, and does not include time spent waiting during the following:
+
+- `wait.for` calls
+- `triggerAndWait` calls
+- `batchTriggerAndWait` calls
+
+You can inspect the CPU time of a task inside the run function with our `usage` utility:
+
+```ts /trigger/max-duration.ts
+import { task, usage } from "@trigger.dev/sdk";
+
+export const maxDurationTask = task({
+  id: "max-duration-task",
+  maxDuration: 300, // 300 seconds or 5 minutes
+  run: async (payload: any, { ctx }) => {
+    let currentUsage = usage.getCurrent();
+
+    currentUsage.attempt.durationMs; // The CPU time in milliseconds since the start of the run
+  },
+});
+```
+
+The above value will be compared to the `maxDuration` you set. If the task exceeds the `maxDuration`, it will be stopped with the following error:
+
+![Max duration error](/runs/max-duration-error.png)
+
+## Configuring for a task
+
+You can set a `maxDuration` on a specific task:
+
+```ts /trigger/max-duration-task.ts
+import { task } from "@trigger.dev/sdk";
+
+export const maxDurationTask = task({
+  id: "max-duration-task",
+  maxDuration: 300, // 300 seconds or 5 minutes
+  run: async (payload: any, { ctx }) => {
+    //...
+  },
+});
+```
+
+This will override the default `maxDuration` set in the config file. If you have a config file with a default `maxDuration` of 60 seconds, and you set a `maxDuration` of 300 seconds on a task, the task will run for 300 seconds.
+
+You can "turn off" the Max duration set in your config file for a specific task like so:
+
+```ts /trigger/max-duration-task.ts
+import { task, timeout } from "@trigger.dev/sdk";
+
+export const maxDurationTask = task({
+  id: "max-duration-task",
+  maxDuration: timeout.None, // No max duration
+  run: async (payload: any, { ctx }) => {
+    //...
+  },
+});
+```
+
+## Configuring for a run
+
+You can set a `maxDuration` on a specific run when you trigger a task:
+
+```ts /trigger/max-duration.ts
+import { maxDurationTask } from "./trigger/max-duration-task";
+
+// Trigger the task with a maxDuration of 300 seconds
+const run = await maxDurationTask.trigger(
+  { foo: "bar" },
+  {
+    maxDuration: 300, // 300 seconds or 5 minutes
+  }
+);
+```
+
+You can also set the `maxDuration` to `timeout.None` to turn off the max duration for a specific run:
+
+```ts /trigger/max-duration.ts
+import { maxDurationTask } from "./trigger/max-duration-task";
+import { timeout } from "@trigger.dev/sdk";
+
+// Trigger the task with no maxDuration
+const run = await maxDurationTask.trigger(
+  { foo: "bar" },
+  {
+    maxDuration: timeout.None, // No max duration
+  }
+);
+```
+
+## maxDuration in run context
+
+You can access the `maxDuration` set for a run in the run context:
+
+```ts /trigger/max-duration-task.ts
+import { task } from "@trigger.dev/sdk";
+
+export const maxDurationTask = task({
+  id: "max-duration-task",
+  maxDuration: 300, // 300 seconds or 5 minutes
+  run: async (payload: any, { ctx }) => {
+    console.log(ctx.run.maxDuration); // 300
+  },
+});
+```
+
+## maxDuration and lifecycle functions
+
+When a task run exceeds the `maxDuration`, the lifecycle functions `cleanup`, `onSuccess`, and `onFailure` will not be called.
