How do you get help if you get hurt while mountain biking alone?
If you get hurt mountain biking alone, call 911 when the injury is serious and you have signal, then send your location to a trusted person. Mountain bike crashes often happen on technical descents far from the trailhead, where an ambulance can't drive to you. That means your Guardian needs your trail system, your planned loop and a return time before you ride, and you need enough gear to stay warm and visible while a rescue team works out how to reach you.
Step by step
01Stop and assess before you move
After a big crash, lie still for a moment. Check for neck pain, numbness, a head strike and whether you can bear weight. If your neck hurts or you lost consciousness, don't try to ride out. Call 911 and describe where you are the way the trail signs do: "I crashed on the lower section of Rattlesnake Trail at Oak Hills bike park, just below junction marker 14, about a mile and a half from the main lot. I hit my head and can't move my left arm." Many networks number their junction posts, and that number is gold to a rescue team.
02Tell your Guardian the trail system and loop
Trail networks have dozens of named segments. Before you ride, send your Guardian the park, the trailhead and the loop you plan. On a phone map, a dot in the woods means little to a dispatcher, but "the lower section of a named trail, above the creek crossing" does.
03Share your live link and set a return time
Start a Holler share at the trailhead and set a return time for the ride. If you haven't checked in five minutes after it, your Guardians get an overdue alert even if your phone app is closed. Tap SOS if you're hurt so they get your location right away.
04Get yourself visible and warm
Pull your bike somewhere visible from the trail, since other riders are often the first to find you. Put on a layer, eat something, and keep your helmet on. Evenings in the woods cool quickly once you stop moving.
05Let your Guardian coordinate
Holler never contacts 911 on its own. If you can't get a call through, your Guardian can call with your last known location and your trail details. They may also know which trailhead or fire road gives rescuers the fastest access.
Related questions
Does crash detection work on mountain bike trails?
Holler's crash detection is an opt-in beta. After a possible hard fall and stillness, it starts an "Are you OK?" countdown and alerts Guardians if you don't answer. Rough descents and drops can trigger false alarms, and some real crashes won't register, so the return time is your stronger backstop. Our crash detection explainer covers the tradeoffs.
What if I'm hurt but can still ride?
Ride slowly to the nearest trailhead or fire road, not back the way you came if that means climbing. Message your Guardian that you're hurt and heading out. If symptoms get worse, stop and call 911. Our guide on what to do after a bike crash covers head-injury warning signs.
What does a realistic solo ride plan look like?
Say you ride an after-work loop of about 12 miles and are normally back at the car by 7:30. You start a live link with your partner as Guardian, set an 8:00 return time and turn on crash detection (beta). You go over the bars on a rock garden at 6:50 with a sore wrist and a cracked helmet. You call 911, tap SOS, pull the bike beside the trail and put on your jacket. Your partner acknowledges the alert and heads to the trailhead to guide the crew in.
Should I ride with a first aid kit?
Yes. A small kit with gauze, tape, wound closure strips and a compact emergency blanket fits in a hip pack. Road rash, deep cuts from pedals and rocks, and waiting in the cold are the most common problems on a solo ride.
What about trails with no signal at all?
Plan as if you'll have none. Tell your Guardian the loop, set a return time, and consider a satellite messenger for remote networks. Your live link will show your last known location, which narrows the search to the section where you went quiet.
