TRAIL TRAUMA: FIRST RESPONSE FOR RIDERS
12 min · Free lesson · written lesson, video in production
After this lesson you can run the first ten minutes after a serious mountain bike crash: the scene call, the major-trauma priorities, splinting broken limbs with what the trail offers, and the head and spine precautions that protect a mate from a second, permanent injury.
The Technique
- Bike crashes produce a known injury menu - collarbones, wrists, shoulders, ribs, and the ones that matter most: head knocks, spines and big bleeds. Your first job is not medical, it is scene command: riders stopped above the crash, one person in charge, the casualty approached still and calm. A second rider hitting the crash site is the classic compounding disaster.
- The priority order is the remote first aid sequence and it does not bend: catastrophic bleeding first - hard direct pressure immediately - then response, airway, breathing. Everything else, including obvious deformity and screaming, waits behind those.
- Head injuries: any knock that dazed them, cracked the helmet, or cost them memory of the crash ends the riding day, full stop. Watch for the red flags - worsening headache, vomiting, confusion, unequal pupils, drowsiness - and treat any of them as an evacuation, not an observation. The helmet comes off only if the airway needs it, and then with two people, slow.
- Spine precautions: a rider with neck or back pain, tingling, numbness, or any altered consciousness after a big hit is treated as a spinal injury - which means they stay where they are, held still and warm, and help comes to them. The walk-it-off instinct is the enemy; a moved unstable spine is how bad days become lifelong ones.
- Splinting on trail: broken limbs are splinted roughly where they lie - padded with spare layers, structured with what the trail bag offers (pump, tyre lever, sticks, a rolled mat), tied with tubes or straps - and checked beyond the injury for warmth, movement and feeling before and after, every fifteen minutes. Collarbones and shoulders want a sling from a spare tube or jersey, arm pinned gently to the chest.
- Package and decide: insulation under them the moment the survey is done - trail dirt steals heat like snow does - then the honest evacuation question: can they genuinely ride or walk out, or does help come here? Adrenaline lies for about twenty minutes; decide after it wears off, not before.
- Prevention closes the loop: the pads-for-the-descent rule from the gear lesson, riding within sight of your group, and the trip brief that names the nearest trailhead and who carries the kit - the first aid you did before the crash.
Common Mistakes
Sitting the casualty up to see how they are. Fix: the assessment happens where they lie - sitting up is a decision the survey earns, not an opener.
- Splinting so enthusiastically the hand goes cold. Fix: warmth, movement, feeling - before, after, and every fifteen minutes; a splint that stops blood flow is a second injury.
The Drill
The trailside scenario: one mate plays a crashed rider with a chosen injury card - collarbone, forearm, head knock, back pain. Run the full sequence from scene command to the evacuation decision with only your actual riding pack. Ten minutes, then swap. Do it once a season and the real one will feel rehearsed.
Head and spine management must be learned hands-on - this lesson tells you what not to do; a wilderness first aid course teaches you what to do, and we arrange rider-specific ones with working paramedics. This content is general guidance, not medical advice.
