What to Prepare: Chongqing's famous fog can limit visibility early on — watch your footing. Humidity is the real challenge here; wear light, breathable fabrics and start hydrating the day before. The hilly terrain means you'll heat up faster than on flat courses.

Wind Impact on Race Day

Winds peaking around 13.9 km/h — the typical daily maximum for this date — can affect your pace by 5-15 seconds per kilometer in exposed stretches. Headwinds slow you down exponentially: a 20 km/h wind costs more than twice a 10 km/h wind.
