What should you do if you fall while mountain biking alone?
If you fall while mountain biking alone, stay still for a moment and check your neck, head and collarbones before you move. Big crashes over the bars can injure the spine, so don't jump up if your neck hurts or you feel tingling. Call 911 for any head strike with confusion, neck pain or a suspected break. For lesser falls, clear the trail, fix the bike, tell your Guardian and ride the easiest route out.
Step by step
01Don't rush to stand
Over-the-bars crashes and hard slams on rocks happen fast. Lie still, wiggle your fingers and toes, and notice any neck pain or numbness. If anything feels wrong in your neck or back, stay where you are and call 911 or ask a passing rider to. NHS guidance treats a head injury from a fall of more than 1 metre as an ambulance call, and going over the bars easily counts.
02Clear the line if you can
Once you know you can move, get yourself and your bike off the trail. Riders coming down a blind descent won't expect a person in the line. If you can't move, prop the bike upright uphill of you as a warning.
03Check your helmet and your head
A cracked or dented helmet means your head took a real hit. Watch for a headache that builds, nausea, confusion, drowsiness or blurred or double vision, which the CDC lists among concussion danger signs. With any of those, stop riding and call for help. The Bicycle Helmet Safety Institute says to replace a helmet after any crash where your head hit, even if it looks fine.
04Do a quick bike check
Look at the bars, stem, brake levers, derailleur and wheels. Bent levers and a twisted stem are common and fixable with a multitool. A cracked frame, broken wheel or failing brakes mean walking out, not riding down.
05Pick the gentlest way out and tell your Guardian
Message your Guardian where you fell and how you are. Use your trail app to find the nearest fire road or gentle trail to the car rather than the technical way back. If you set a Holler return time, extend it so the overdue alert matches your new pace.
Related questions
Does crash detection work for mountain bike falls?
Holler's opt-in crash detection beta looks for a possible hard fall followed by stillness, then asks "Are you OK?" and alerts Guardians if you don't answer. Big hits are more likely to register than slow tip-overs, and jumps can false-alarm. Our crash detection explainer covers the tradeoffs.
What first aid should I carry mountain biking?
Gauze, tape, wound closure strips, a small bandage roll, pain relief, and an emergency blanket. Pedal gashes and deep scrapes are common, and wrapping a sprained wrist lets you walk your bike out.
What if I crash deep in a trail network?
Call 911 if you're badly hurt, and give the trail name and the nearest numbered junction post or named feature, since networks can be confusing on a map. Then tap SOS so your Guardian sees your location. Our answer on getting help if you're hurt mountain biking alone covers what to say.
What does a sensible response to a mid-ride crash look like?
Say you wash out on a root in a berm four miles from the lot and slam your shoulder. You lie still, check your neck, then drag the bike off the line. Your helmet has a crack, your shoulder aches but moves, and your brake lever is bent. You straighten the lever, message your Guardian, and take the fire road back instead of the technical descent. That evening you order a new helmet.
Should I keep riding after a minor crash?
If you and the bike are both fine, ride on at a lower intensity and skip features you were planning to try. Confidence and reflexes take a hit after a fall, which makes a second crash more likely that same day.
