01·Course Characteristics
While physically flat and fast, the true test of this scenic lakeside course is the immense physiological demand of racing at 1,970 meters above sea level.
There's still hope!
The ideal build for this course is 16 weeks, and you have 8. We'll compress the essentials into your remaining time, prioritizing the demands that matter most on this course to get you to the finish line.
02·Course by Section
A single-loop counterclockwise swim in the pristine, calm freshwater of Erhai Lake, backdropped by the majestic Cang Mountain. Water temperatures hover between 17°C and 20°C, making wetsuits highly likely or mandatory.
A flat, fast three-lap course on high-quality asphalt directly alongside Erhai Lake. While the climbing is minimal at 150 to 250 meters, athletes must remain aerodynamic and prepare for potential lakeside winds.
A flat, two-lap run along a paved, vehicle-free ecological corridor offering beautiful mountain views. The entire path is right on the shoreline, exposing you to direct sunshine with very little natural shade.
03·AVG beginners' Training Timeline
Because Dali is flat but sits at 1,970 meters, this 16-week plan focuses heavily on expanding your cardiovascular capacity. We front-load aerobic volume and progressively build sustained flat-line power, preparing you to maintain an aggressive aerodynamic position while managing the increased cardiac strain of thin air.
Aerobic Engine & Capacity
Build a strong cardiovascular base to handle the oxygen-deprived environment.
Sustained Aerobic Power
Develop consistent muscular endurance and posture for the flat, aerobar-heavy bike ride.
Altitude & Muscular Stamina
Introduce race-pace simulation workouts under metabolic stress to mimic high-altitude breathing.
Specific Build & Simulation
Execute long, flat brick sessions to adapt your legs to running on flat, unshaded terrain.
Taper & Acclimatization
Reduce training volume significantly and arrive early at 1,970 meters to acclimatize.
Adapts to your fitness, schedule & recovery every week.

With temperatures peaking around 24°C and minimal shade on the run, prepare for direct sun exposure. Regularly pour water over your head at aid stations and use sponges to keep your core temperature down.
The dry, 1,970-meter air accelerates dehydration and slows gastric emptying. Consume 600 to 1,000 ml of fluid per hour heavily spiked with sodium, and stick to 60 to 90 grams of easily digestible liquid carbs or gels.
Lower your target power and pace by 5-10% early on to account for the thinner air at high altitude. Maintain a conservative, steady effort on the flat bike to save your lungs for the run.
Arrive 5 to 7 days before the race to allow your body to acclimatize to the 1,970-meter elevation. Pack a full-sleeve wetsuit for the 17-20°C lake water, and secure your Chinese entry visa well in advance.
The entire event is held at a high altitude of approximately 1,970 meters (6,463 feet) above sea level, which is the primary physiological challenge of the race. Despite the thin air, the course profile itself is exceptionally flat, featuring a swim with zero elevation gain, a bike course with only 150 to 250 meters of gain, and a run course with less than 50 meters of total gain.
Physically, the 90 km bike course is nearly flat, highly accessible, and designed as a fast three-lap loop on high-quality asphalt around Erhai Lake with only 150 to 250 meters of total elevation gain. However, the overall difficulty is rated as Medium-High because the high altitude of 1,970 meters reduces oxygen availability, which can lower your power output and raise your heart rate. You will need to pace yourself carefully and prepare for potential wind exposure coming off the lake.
The water temperature in Erhai Lake typically hovers between 17°C and 20°C (63°F to 68°F) in mid-September. This means the 1.9 km single-loop swim is highly likely to be wetsuit-legal or even wetsuit-mandatory. You will self-seed for the swim start in calm, pristine freshwater backdropped by the Cangshan mountains.
Because you are racing at an altitude of 1,970 meters where the air is drier, you will dehydrate much faster due to lower humidity and increased respiration. You should aggressively target 600 to 1,000 ml of fluid per hour, heavily supplemented with sodium and electrolytes. Additionally, aim for 60 to 90 grams of carbohydrates per hour using easily digestible options like gels, as high altitudes can slow your gastric emptying.
It is highly recommended that you arrive in Dali at least 5 to 7 days before race day on September 13, 2026, to allow your body to physiologically adjust to the altitude of 1,970 meters. You can access the venue via Dali Fengyi Airport (DLU) or take a 2-hour high-speed train from Kunming. Make sure to secure your Chinese entry visa well in advance of your travel.
