The mobile app is what you actually use on race day. It runs the plan you built on the web — pacing, fueling, gear, checkpoints, alerts — fully offline.

​
Install

Search Absurd Running in the App Store, or open the link from absurdrunning.com on your iPhone and tap Get.

​
Sign in

Use the same account you signed up with on the web. Your routes and plans sync automatically.

​
Download a plan for race day

Plans run online by default, but you’ll want to download them for race day so they keep working without signal.
1

Open the plan

From the Plans tab, tap the plan you want to run.
2

Tap Download

The plan details + map tiles for the route get saved locally to your phone. Map tile download takes longer than the plan itself — start it before you leave the house.
3

Verify offline

Toggle airplane mode on. Open the plan again — everything still works. Toggle airplane mode off.

​
On race day

  • Open the plan when you start running.
  • The app shows you which segment you’re on, your target pace, what to eat, what to wear at the next checkpoint, and what’s in your drop bag.
  • Per-checkpoint alerts fire as you approach each one.
  • No notifications repeat — if you miss one, you’ll see it in the timeline.

​
Things to know

  • Battery: keep your phone in low-power mode and screen brightness low. The map view is the biggest power draw.
  • Watch integration: Apple Watch and Garmin support is in progress. For now, alerts come through your phone.
  • Updates: keep the app on the latest version before race day. Updates ship frequently and the plan format may evolve.
