Personalize this timeline04·Race-Day Execution
Temperatures start near a crisp 12°C at dawn and peak around 22°C. Keep a lightweight, windproof layer in your transition bag to stay comfortable during the early miles of the bike leg.
Aim for 80 to 90 grams of carbohydrates and 600 to 750 milliliters of fluid per hour. The mild autumn weather can mask your actual sweat rate, so set a strict repeating alarm to maintain hydration.
Avoid the temptation to surge on the deceptively fast, flat river loops of the bike course. Save your muscular energy for the marathon, where a highly metronomic pace will yield the fastest run split.
A deep-section rear wheel or disc is ideal for this fast, low-wind course. Pack a full-sleeved wetsuit for the cool freshwater lake, and utilize standard road tires inflated for smooth asphalt.
The swim takes place in Jirisan Lake, featuring a fresh water, rolling start layout. The water is usually calm with temperatures typically allowing for wetsuits, but you should prepare for potentially warm conditions depending on the autumn transition. It is highly recommended to practice sighting in open freshwater lakes prior to race day.
The bike course features rolling hills with scenic views of the Seomjin River and Jirisan National Park, rather than extreme alpine climbs. You can expect a fast, well-paved course, but you must pace yourself through the steady, gradual inclines to save your legs for the run. Aerobar comfort and consistent power output are critical for success on this multi-lap course.
The run course is primarily flat and fast, winding through local villages and agricultural fields surrounding the event hub. While the flat terrain is forgiving, October weather in Gurye can bring high humidity or midday heat, so managing your hydration and salt intake early is vital. Spectator support is highly concentrated around the main stadium transition area to boost your spirits.
In early October, Gurye experiences pleasant autumn weather with average daytime highs ranging from 18°C to 24°C (64°F to 75°F). While mornings can be quite cool, particularly by the lake, the midday sun can feel strong on the exposed run course. You should prepare clothing layers for a chilly morning transition and plan for standard heat management during the afternoon.
It is best to arrive in South Korea at least 4 to 5 days before the race on October 4, 2026, especially if you are traveling across multiple time zones. This allows your body to adjust to the local time, complete crucial bike reassembly checks, and scout the Jirisan Lake transition venue. Additionally, arriving early ensures you have ample time to navigate travel logistics from Seoul's Incheon International Airport down to the Gurye region.
