Trail Running Gear Checklist: Complete Guide to Mandatory Gear, Hydration Packs, Trekking Poles, and Headlamps

Why Is There “Mandatory Gear”?

Trail running races are mostly held in mountainous areas, where weather can shift from blazing sun to thunderstorms within an hour, and temperatures can drop from 30°C to 5°C. Mandatory gear is required by race organizers so you can self-rescue in the worst-case scenario—failing to carry all items may result in disqualification.

ITRA International Standard Mandatory Gear (Graded by Distance)

Short Distance (<25K)

• Mobile phone (fully charged)

Medium Distance (25-50K)

All of the above plus:

• Emergency blanket (140×200cm)
• Self-adhesive bandage
• Personal food supply (500-800 kcal)
• Headlamp (even for daytime races)
• Spare batteries

Long Distance/Ultramarathon (50K+)

All of the above plus:

• Waterproof jacket (with taped seams)
• Waterproof pants (for some races)
• Long-sleeve thermal layer (>180g/m² merino or equivalent)
• Gloves + thermal hat
• Second headlamp
• Whistle
• Cup (essential for zero-waste races)

• Some races require crampons and rope (very rare)

Choosing a Hydration Vest / Pack

Capacity Comparison

Key Fit Points

1. No vest bouncing: Jump around while wearing it—there should be no significant shifting
2. Chest strap position: Should not press on your chest or constrict your breasts
3. Bottle placement: Front chest bottles should be easy to access and stow
4. Rear capacity: Must fit a rain jacket + thermal layer + food

Soft Flasks vs. Hydration Bladder

• Soft flasks (500ml ×2): Easy to access, you can see how much remains
• Hydration bladder (1.5-2L): Large capacity but more hassle to stop and refill
• Hybrid setup: Front soft flasks + rear bladder, commonly used in ultramarathons

Choosing Trekking Poles

Pole length formula: Height × 0.66-0.68 (cm)

• Height 170cm → Pole length approx. 115cm

Choosing a Headlamp

Lumen Output Guide

Battery Life

• Look at runtime at medium brightness (manufacturers often inflate numbers using the lowest setting)
• For 100-mile races, carry at least 12-16 hours of battery capacity

Recommended Headlamp Specs

• Main light: Petzl NAO+, Silva Trail Speed 5XT, BD Spot 400
• Backup light: Compact 100-200 lumen model that can attach to a waist pack or chest strap

Tips for Combining Hydration Vests and Headlamps

• Store headlamp batteries in the vest’s inner pocket (keeps them warm, prevents voltage drop in low temperatures)
• Keep the backup headlamp in a separate pocket so you can find it even in the rain
• Route the headlamp strap under the brim of your cap to reduce light bounce in front of your eyes

Common Mistakes

1. Buying gear only right before the race: Blisters, poor fit, chafing
2. Skimping on gear weight: Thermal layer too thin, hypothermia at the summit
3. Not practicing putting gear on and off: Need to grab your rain jacket in a technical section but can’t get it on in 10 minutes
4. Not checking batteries: Headlamp dies halfway through the race

One-Week Pre-Race Gear Checklist

• [ ] All mandatory gear gathered (per race regulations)
• [ ] Hydration vest test-fitted with weight (including water and food)
• [ ] Headlamp charged and fitted with fresh batteries
• [ ] Rain jacket waterproof test (spray water to confirm seams don’t leak)
• [ ] Poles extended and tested (telescoping sections don’t stick)
• [ ] First aid kit checked (no expired bandages)

Conclusion

Trail running gear isn’t about “the more you prepare, the better”—it’s about matching gear to risk scenarios. Think through the course elevation, estimated time, and weather conditions, and your gear list will practically write itself.
