When should you worry if someone is late back from running?
For a road run of under an hour, 15 minutes late is normal: an extra loop, a chat, a coffee stop. Start actively checking at about 30 minutes past the time they gave you, sooner if it is dark, very hot or they have a medical condition. If they miss two calls and their live location hasn't moved in 20 minutes or more, go to where they last were or call 911. You never have to wait hours before asking for help.
What to do, in order
01Work out how late is actually late
Runners often underestimate how long a run takes, and a planned 5 miles can quietly become 7. Ask yourself how long this person's usual runs take and whether they mentioned a longer route today. A runner on a 45 minute loop who is 40 minutes over is a different situation from a marathoner on a three hour long run who is 20 minutes over.
02Open their live link and read the timestamp
If they shared a live location link, look at two things: where the dot is and how long ago it last updated. A dot moving at running pace with a fresh update means they are fine and just slow. A fresh update from a dot that has sat in a park or on a quiet road for 20 minutes deserves a call. If the page marks the location as stale, the phone has stopped sending (dead battery or no signal), and the last known location stays on the map with the route line leading to it. With Holler, the link opens in any browser.
03Call twice, then message
Call, wait a minute, call again. Many runners carry the phone in a waist belt with the ringer muted, so a second call often gets picked up when the first one didn't. Then send a short message: "You OK? Reply when you see this." Write down the time of each attempt; a dispatcher may ask.
04Call someone closer than you
A running partner, a neighbor who lives near the route or the shop where they usually stop can often check faster than you can. Give them the exact spot from the live link, not just the neighborhood.
05Go to the last known location, ideally with someone
If the link shows them stopped and they aren't answering, drive or walk to that spot with a charged phone and a flashlight if it's getting dark. Check both sides of the road and the path edges. If you find them hurt, call 911 first, then help. If they aren't there, call 911 and say exactly where you looked.
06Call 911 and give the dispatcher a clear picture
Call right away if they sent an SOS, if the link stopped on a road shoulder or remote path and they won't answer, if it is dark and they have no light, or if they have diabetes, epilepsy or a heart condition. Tell the dispatcher: their name and age, what they are wearing (shoe and top colors), the route they planned, the last known location and the time it was recorded, any medical conditions, and whether they carry ID or a phone. Our guide on when to call 911 if someone is overdue walks through the call.

Do police make you wait 24 hours before reporting a missing adult?
No. That is a myth from television. California's Attorney General says there is no waiting period to report a person missing, and New York City's 311 service says you do not have to wait 24 hours. If you believe a runner is in danger, call 911 now; the dispatcher decides how to respond.
What if the live link froze an hour ago?
A frozen link usually means the phone lost signal or the battery died, not that the runner stopped. Look at where it froze and how long ago. If they would have been home well within the time since the last update and still aren't, treat it the same as no movement and start calling. Our explainer on cell dead zones covers why links go quiet.
How can a runner make this easier for me?
Ask them to set a return time before they head out. If they haven't checked in five minutes after it, Holler's server sends you an overdue alert even if their phone app is closed, so you aren't left watching the clock. Being a calm contact is a skill; our guide on being a good safety contact walks through it.
I got an overdue alert. Does tapping acknowledge send anyone?
No. Acknowledging only tells the runner and any other Guardians that someone is checking, so you don't all call at once. Holler never contacts 911. If the steps above point to trouble, you make that call.
Should I post on social media or local running groups?
Call 911 first if you think they are hurt or missing. After that, a message to their running club asking whether anyone saw them on a named route can help, because other runners use the same paths. Share the route and a description, never their home address.
