Trail Running Night Safety: A Complete Guide from Headlamps to Routes

Introduction

The UTMB starts at 18:00 in the evening, and a Nenggao Andongjun traverse inevitably means starting or arriving in the dark. Night running is the norm in trail running, but statistics show that 40% of falls, getting lost, and ankle sprains in trail running occur at night. This article compiles 7 key safety rules.

1. Headlamp: The Single Most Important Piece of Gear

Recommended brands: Petzl, Black Diamond, Ledlenser, Fenix

2. Headlamp Usage Tips

• Set 3 brightness levels to save battery
• Carry spare batteries
• Wear it under the brim of your cap to keep moths off your face
• Aim your gaze slightly higher, illuminating 5-10 meters ahead
• When running with teammates, avoid shining lights in each other’s eyes

3. Clothing and Reflectivity

• Sew reflective strips onto your pack and hat
• Wear fluorescent clothing to increase visibility
• Carry a lightweight insulating layer (mountain nights <10°C)
• Wear a windproof cap to keep your neck warm

4. Route Selection Principles

Night running routes should meet the following criteria:

• High familiarity (run during the day at least 3 times)
• Clear paths (avoid complex junctions)
• Well-defined emergency exit points
• Areas with good signal

Recommended night running routes in Taiwan:

• Yangmingshan Erziping Trail: Gentle terrain, good signal
• Daan Forest Park: Pure urban warm-up
• Wulai Neidong Front Section: Short-distance technical practice
• Hohuan Mountain Road: High altitude but wide road

5. Nighttime Visual Deterioration

At night, peripheral vision deteriorates, affecting:

• Depth perception by 30%
• Reaction time by 20-40%
• Color recognition significantly

Countermeasures:

• Increase cadence, shorten stride
• Reduce pace by 15-20%
• Continuously scan your gaze rather than fixating
• Be more cautious on ascents and descents

6. Emergency Response

• Carry a phone (fully charged + power bank)
• Inform family of your route and estimated time
• Carry an emergency whistle
• Learn basic first aid
• Carry NT$100 in small bills (for a taxi)

7. The Rule of 3

Night trail runs are recommended with 3 or more people:

• 1 leader
• 1 sweep at the back
• Those in the middle look out for each other

Solo night running carries too much risk, unless on a familiar short route.

Practical Advice

• Start night running training 4 weeks before a race to adapt your vision
• Practice with regular partners to build coordination
• Avoid technical sections on rainy nights
• Mark your supplies with reflective tags to avoid missing them
• Take a hot shower and consume carbohydrates immediately after running

Conclusion

Night running is the “rite of passage” of trail running. From Yangmingshan Erziping to the UTMB start line, every night run builds experience. Safety first, then chase speed. Only when you learn to coexist with the darkness are you a true trail runner.
