Runner World interpretation: Trail running presents unique terrain challenges that can increase the likelihood of falls and related injuries. Recent systematic reviews have identified both intrinsic characteristics, such as runner experience, and extrinsic conditions, including warm‑up practices, training surfaces, and psychological factors, that influence injury risk. By integrating these peer‑reviewed findings, runners can consider evidence‑informed adjustments to preparation, surface selection, stability monitoring, and behavioral planning to help reduce fall risk while acknowledging individual variability.

This guide is general educational information, not a diagnosis, treatment plan or individualized exercise prescription. Recent surgery, pregnancy, chronic illness, medication concerns, significant symptoms and return from injury require advice from an appropriately qualified clinician.
Understanding Risk Factors
Peer-reviewed finding: A living systematic review of trail‑running injuries examined 19 studies involving 2,785 participants and identified several intrinsic and extrinsic factors linked to higher injury incidence. Intrinsic factors associated with injury included greater running experience, higher competition level, and higher scores on the Propensity to Accident Questionnaire. Extrinsic factors associated with injury comprised skipping warm‑up, lacking a specialised training plan, training on asphalt, double daily sessions, and occupations involving physical labour. Evidence basis: PMID 35022162
Runner World interpretation: While the review reports these associations, some intrinsic factors such as extensive experience may reflect greater exposure rather than a direct causal effect. Adjusting modifiable extrinsic factors—like incorporating consistent warm‑ups, following a structured training plan, and limiting repetitive high‑impact sessions—could help mitigate risk, but individual circumstances differ. Consulting a qualified professional can tailor strategies to personal history and goals. Evidence basis: PMID 35022162
Warm‑up and Preparation
Runner World interpretation: The systematic review highlighted neglecting a warm‑up as an extrinsic factor that was repeatedly linked with injury among trail runners. Although the studies did not provide precise risk estimates, the consistent identification of this practice suggests that omitting preparatory activity may be associated with a greater chance of injury during technical runs. Evidence basis: PMID 35022162
Runner World interpretation: Runners may therefore add brief, terrain‑specific activation routines before each outing, focusing on dynamic movements that engage the lower‑body muscles used on slopes. The exact content and duration of such warm‑ups have not been defined in the literature, so seeking guidance from a qualified coach can help select appropriate exercises. Evidence basis: PMID 35022162
Training Surface and Environment
Runner World interpretation: The review reported that training on asphalt, compared with natural trail surfaces, was associated with a higher incidence of injury among trail runners. While the evidence does not quantify the magnitude of risk, the repeated observation across studies indicates that harder, less forgiving surfaces may increase musculoskeletal stress during running. Evidence basis: PMID 35022162
Runner World interpretation: To apply this insight, runners can prioritize trail sessions over pavement workouts and introduce any necessary pavement training gradually within a structured plan. When pavement work is unavoidable, using supportive footwear and limiting session length may help offset added stress, but individualized assessment remains important. Evidence basis: PMID 35022162
Dynamic Stability Monitoring
Peer-reviewed finding: A narrative review of accelerometer‑based studies described that trunk acceleration indices, such as cycle repeatability and signal dispersion, can be used to assess dynamic stability during locomotion on varied surfaces. Fifteen studies employing a lumbar‑placed tri‑axial sensor demonstrated the feasibility of these metrics in asymptomatic participants, although most recordings were performed indoors rather than in outdoor trail conditions. Evidence basis: PMID 31456487
Runner World interpretation: Runners interested in monitoring stability may use wearable devices that capture lumbar acceleration and review repeatability scores across runs. While these tools show promise for quantifying movement consistency, the current evidence does not yet confirm that the metrics predict real‑world trail falls, so they should complement professional assessment rather than replace it. Evidence basis: PMID 31456487
Behavioral Strategies for Injury Prevention
Peer-reviewed finding: A prospective cohort study applying the Theory of Planned Behavior found that higher intention, positive attitude, supportive subjective norms, and greater perceived behavioral control each predicted increased engagement in injury‑preventive actions among trail runners. Together these determinants explained roughly half of the variance in preventive behavior, highlighting the psychological component of injury risk management. Evidence basis: PMID 34001423
Runner World interpretation: Based on these findings, runners can set specific injury‑prevention goals, seek feedback from peers or coaches, and enhance perceived control by planning routes, selecting appropriate gear, and scheduling rest. Strengthening intention and attitude through goal‑setting may foster consistent preventive actions, though personal motivation and context will influence outcomes. Evidence basis: PMID 34001423
