Running in the Tropics: The Ultimate Half Marathon Packing Guide
Preparing for a half marathon in a tropical climate like Sabah requires more than just stamina and determination. The heat, humidity, and potential for rain demand specific gear and thoughtful packing. Whether you’re a first-timer running the Borneo Half Marathon or a seasoned athlete racing in Southeast Asia, this guide will help you pack smart so you can stay cool, comfortable, and focused from start to finish.
Lightweight and Breathable Clothing
Choose running apparel made from moisture-wicking, quick-drying fabrics such as polyester or technical blends. Avoid cotton as it traps sweat and increases the risk of chafing. A lightweight singlet or tee and breathable shorts will keep you cool during the race.

Stay cool and dry with lightweight clothing designed for humid runs.
Proper Footwear and Socks
Your shoes should be well broken in and suited for pavement running. Consider shoes with good ventilation to allow airflow and drainage if it rains. Pair them with synthetic or wool-blend socks that help prevent blisters and wick away moisture.

Reliable shoes and breathable socks are essential for tropical conditions.
Sun Protection Essentials
Even with an early morning race start, the tropical sun rises fast. Pack a running cap or visor, sunglasses with UV protection, and a sweat-resistant sunscreen rated SPF 30 or higher. Apply sunscreen to exposed areas before the race and reapply after.
Race Day Essentials
Do not forget your race bib, timing chip, identification, and a copy of your race confirmation. Pack them the night before to avoid stress in the morning. A small towel, reusable bag, and extra face mask (if required) are also handy.
Travel and Weather Considerations
Check Sabah’s weather forecast before flying in. Light rain is common, so a compact poncho or waterproof jacket is useful. A power bank, extra phone charger, and a small first-aid kit are also helpful, especially for international runners.

A few thoughtful extras make race travel easier and less stressful.
