This retrospective analysis of 6643 mountain bike-related ED presentations over 15 years in Tasmania documents a 3-fold increase in MTB injury prevalence after trail development in 2015, with concurrent increases in clinical urgency and ambulance arrivals. The data are descriptive and observational; the association between trail development and injury burden cannot be causal without exclusion of confounding factors such as increased MTB participation or improved injury identification.
Retrospective cohort analysis, pre-post comparison. All mountain bike-related injury presentations to Tasmanian public hospital emergency departments over 15 years. Age range widened from 10–50 years pre-trail to 5–80 years post-trail. Males comprised 80% pre-trail and 85% post-trail.. Intervention: Purpose-built mountain bike trail development in 2015 (observational exposure, not an intervention administered by researchers). Compared with: Pre-trail development period (2010–2014) vs post-trail development period (2015–2024). n = 6,643. Tasmania, Australia (public hospital emergency departments).
MTB-related ED presentations increased 3-fold post-trail development, from 1.0 to 3.6 per 1000 ED presentations (n=743 to 5900) ATS category 1 (most urgent) presentations increased 375% from 0.8 (0.8) to 3.8 (2.8) mean (SD) presentations/year ATS category 2 presentations increased 1343% from 8.2 (4.0) to 118.3 (65.5) presentations/year
Mortality data sparse (4 deaths total); insufficient for comparative or risk estimation analysis
Clinicians and public health professionals in regions considering or with newly developed MTB infrastructure should anticipate significant increases in ED volume, clinical severity, and admission rates. These data support injury prevention and resource planning but do not establish causation; increased participation rates and case identification may partly explain the observed trends.
Retrospective descriptive analysis of injury epidemiology in a single region without a concurrent control group or causal design; provides observational data on trends but cannot establish causation between trail development and injury increases.

Objectives To determine the epidemiology of mountain bike (MTB)-related presentations to public hospital emergency departments (ED) in Tasmania, Australia, pre- and post-development of purpose-built MTB trails. Methods Retrospective analysis of presentations to Tasmanian public hospital EDs pre- and post-MTB trail development in 2015 (total period: 1 st January 2010 to 31 st December 2024). MTB-related injuries were determined from hospital medical records. Epidemiological characteristics were prevalence, clinical urgency (Australasian Triage Scale [ATS] categories 1 to 5, most to least urgent), arrival mode (ambulance vs private transport), mortality, admission rate, seasonal variation, injury profile and patient demographics. Results For the total period, there were 6643 MTB-related presentations. Prevalence increased 3-fold post-trail development, 1.0 to 3.6/1000 ED presentations ( n =743 to 5900) with seasonal burden highest in summer. Clinical urgency increased 375% for ATS category 1 from 0.8 (0.8) mean (SD) to 3.8 (2.8) presentations/year, and 1343% for category 2 from 8.2 (4.0) to 118.3 (65.5) presentations/year. Ambulance arrivals increased 372% from 21.2 (3.6) to 100 (47.6) /year. Hospital admission rate increased 663% post-trail development, from 17.2 (7.4) to 131.3 (64.4) /year. All four deaths were post-trail development. Over the total period, 41.6% of MTB injuries were orthopaedic, soft tissue injuries 27.5%, open wounds 19.3%, and multiple major trauma was 1.8%. Upper extremities were the dominantly injured body region (51.1%). Injured males were more prevalent (pre- 80%, post- 85%). Age distribution widened (10-50 years pre-, 5-80 years post-). 10–14 year-olds had the highest presentations/year increase from 13.8 (7.0) to 118.8 (67.2)/year. Conclusions Increased rates of ED presentations, clinical urgency, and increased arrival by ambulance was observed post purpose-built MTB trail development. This study provides epidemiological data to inform riders about the risks, guide injury prevention strategies and health resource allocation.
