What should you do if you fall while trail running alone?
If you fall while trail running alone, stay down for a moment, step off the singletrack and check your hands, knees, ankles and head. Call 911 if you hit your head on rock and feel confused or nauseous, see a bone out of place or can't bear weight. If you're just cut and bruised, clean the wounds, walk a few hundred yards before running again, and take the shortest route back to the trailhead. Let your Guardian know and adjust your return time.
What to do right after a trail fall
01Let the fall finish, then move off the trail
Trail runners mostly fall forward: a toe catches a root or rock and you land on your hands, knees and sometimes chin. Lie still for a breath, then shift a step or two off the singletrack so a mountain biker coming around the bend doesn't hit you.
02Check what hit the ground
Look at your palms and knees for deep cuts or embedded grit, touch your face and scalp for blood, and roll each ankle gently. If your head hit a rock, notice whether you feel dazed or have blurred vision. Scalp cuts bleed a lot, so press on them with a buff or gauze for several minutes before judging.
03Rinse and cover before you move on
Squirt water from your flask into scrapes to flush out dirt and pick out visible grit. Cover what you can with a bandage or tape so it doesn't rub on your vest straps. The NHS says bleeding you can't stop is an emergency, and a wound still dirty after cleaning needs an urgent appointment.
04Test the leg before you trust it
Walk a few hundred yards. Then try a short, gentle downhill, which loads an ankle or knee more than flat ground. If you're limping, stay at a walk. Shaky legs or dizziness mean eat something, drink and sit for a few minutes before carrying on.
05Head out the short way
Pick the quickest route to the trailhead or a road, even if that means cutting the loop. Message your Guardian where you fell and that you're walking out. If you set a return time, extend it to fit your slower pace. The optional stationary alert still covers you if you stop and can't answer its "Are you OK?" prompt.

What if I can't get back up?
Call 911 and give the trail name and the last junction you passed, then tap SOS so your Guardians see where you are. Put on every layer you carry and sit on your vest. Our answer on getting help if you're hurt trail running alone covers what to tell the dispatcher.
What does handling a typical fall look like?
Say you catch a root on a descent five miles from the car and land hard on both hands and a knee. You move off the trail, rinse the grit out, tape the knee and walk for a few minutes. The downhill test hurts, so you walk the remaining miles, text your Guardian and push your return time back 45 minutes.
Why do I fall more on trails late in a run?
Tired legs lift your feet less, and focus drifts. Shorten your stride on technical sections, look three or four steps ahead, and slow down on descents in the last miles. At dusk, a headlamp with a wide beam helps you see roots. The trail running safety guide covers footing and route choice.
Should I see a doctor after a trail fall?
Yes if you hit your head and later get a worsening headache, repeated vomiting or confusion, which the CDC lists as danger signs. Also get checked if a joint swells badly, a cut is deep or gaping, or scrapes turn red and hot over the next days.
