What to do if someone's location stops moving on a run, ride or hike

First, breathe: most stopped dots have ordinary causes

A location that stops moving is the most common thing that worries a safety contact, and it's worth knowing that most stops are boring. People pause at crossings, refill water, stretch, take a photo, chat with a neighbor, duck into a store or sit on a bench to catch their breath. Cyclists fix flats. Hikers eat lunch at the viewpoint they drove an hour to see.

That doesn't mean you should ignore it. It means your first job is to gather two or three facts quickly, so you can tell a normal pause from a real problem. The steps below are ordered so you spend the first few minutes on the things most likely to give you an answer.

If you're new to this role, our hub on how to be a good safety contact covers the plan you should agree before they leave. Having that plan makes this moment much easier.

Read the map like a clue, not a verdict

A live location map shows where the phone last reported, and when. Those two facts together tell you far more than either one alone. On a Holler link you also see the route they have travelled as a line, so you can tell whether the stop is on their planned loop or somewhere unexpected, and the page marks the location as stale when updates stop arriving.

Phone location is also approximate. Even a Minnesota county 911 center, using its own location tools, says that in good conditions it will get a location within 100 yards of a modern cell phone, and that being indoors or in heavily forested areas makes it less accurate. So a dot that sits just off the trail or on the wrong side of a road may be a small error, not a fall into a ravine. Our explainer on how accurate phone GPS is goes into why.

The steps, in order

Work through these in order. Most of the time you'll have an answer by step two.

When a stop becomes an emergency

There isn't a single right number of minutes, and it would be dishonest to give you one. What matters is how the stop fits the plan and the conditions. The same ten-minute pause means different things for a runner at a city café at noon and a hiker on a ridge an hour before sunset.

Idaho Mountain Search and Rescue advises treating missing or overdue people as an emergency until proven otherwise, and notes that a delay in requesting help can hurt the outcome of a search. That's a useful rule of thumb here too: if your gut says something is wrong and you can't reach them, it's reasonable to call.

Here is how that can play out. Your partner is on a 90-minute trail run with a return time of 8:00. At 7:05 you glance at the link: the dot has not moved in 15 minutes, but the location updated a minute ago, and it sits partway down a switchback, not at the viewpoint. You call twice, no answer. You text their running friend who lives near the trailhead and ask them to drive over. At 7:15, with still no answer, you call 911, say you are not with them, and read out the location and the time it was recorded. Twenty minutes of guessing would have gained nothing. For activity-specific timing, see when to worry if someone is late back from running and from mountain biking.

• They are not answering and the phone is still reporting a location that isn't moving.
• The stop is somewhere with no obvious reason to stop, like the middle of a road, a creek crossing or partway down a descent.
• They are alone, somewhere remote, or it's getting dark, very hot or very cold.
• They have a condition that can cause sudden problems, such as diabetes, epilepsy or a heart condition.
• A stationary alert or crash detection alert fired and they didn't respond to it.

If a stationary alert fired

Some safety apps can watch for this for you. Holler has an optional stationary alert: if the person stops moving for the time they chose, Holler asks them "Are you OK?" on their phone and alerts Guardians if they don't answer. Guardians get the alert by email and by app or browser push, and the live link shows where they stopped and how long ago the location last updated.

A stationary alert carries more weight than a dot you happened to notice, because they were asked directly and didn't respond. Skip straight to calling them and anyone nearby, and move to 911 quickly if you can't reach them. On the Holler live link you can acknowledge the alert so they can see someone is checking on them. Acknowledging does not send help and doesn't mean anyone has arrived.

It's worth knowing the limits. A stationary alert can fire when someone simply forgot to answer, like during a long café stop, and a phone that has lost signal or battery cannot show whether they are moving. Holler cannot sense heat illness, seizures or heart problems directly. Stillness and missed check-ins are how it catches that something may be wrong. Holler never contacts 911 on anyone's behalf.

What to tell a 911 dispatcher

County 911 centers ask callers to be ready to say where the emergency is, what happened, who is involved, and how it happened. When you're calling about someone else's location, lead with the fact that you are not at the scene, then give the location as precisely as you can.

If they are in another town or state, still call 911 from where you are. Tell the dispatcher right away that the person is somewhere else and give the town, county and state. County 911 centers say they transfer calls that need another agency. If they can't, ask for the police or sheriff's number for the county where the person is. Our guide on how to respond to an SOS alert covers this in more detail, and during any Holler alert the live page shows their coordinates ready to read out.

• "I'm calling about my partner, who is out running alone. I'm not with them."
• The last known location: an address, trail and park name, or the latitude and longitude from the map, plus the nearest town and county.
• The time that location was recorded and how long they've been still.
• What they were doing, their planned route and where they started or parked.
• Their name, age, what they're wearing, and any medical conditions or medications.
• Your phone number, and whether you have a live link that is still updating.

Afterward, tune the plan

Most of these episodes end with a call back and an apology. That's a good outcome, and worth a short, blame-free conversation. If stops keep causing worry, the plan probably needs adjusting rather than the Guardian learning to ignore it.

Maybe the stationary delay should be longer for trail runs with photo stops, or they could send a quick "stopping for coffee" message. Maybe they need a battery pack, a clearer return time with more buffer, or a note about a known dead zone on their route. For hikers, a written trip plan makes the "is this stop expected?" question much easier to answer.
