Accuweather forecasts temperatures in Can Tho on Sunday to range from 25-33 degrees Celsius with 91% humidity and a chance of thunderstorms. These conditions are typical for the Mekong Delta during the rainy season. While the temperature is relatively cool, the high humidity and potential rain present a significant challenge for runners, possibly creating slippery conditions.

The 42km race begins at 2:30 a.m., giving runners 3 to 4 hours before the sun's peak intensity. However, as the sun rises, increasing temperatures and heat radiation can lead to rapid dehydration. The high humidity further elevates the risk of heatstroke and exhaustion, demanding caution from participants.

Runners are advised to adjust their pace, slowing down compared to their usual training runs. Regular hydration with water and electrolytes is crucial for maintaining safe energy levels. VnExpress Marathon events provide water stations every 1.5 to 2 km, offering water, electrolytes, and ice. Runners can locate these stations on the course map provided by the organizers.

Experts recommend adapting training strategies to race conditions. Alternating running with short walking breaks or focusing on time-based running rather than fixed distances can aid recovery and prevent overexertion. This approach also mitigates the risk of heatstroke as humidity and temperature rise during the morning.

To combat the humid heat, runners can use cooling towels or gels applied to the neck, nape, or wrists. After finishing, resting in the shade for at least 10 to 15 minutes allows the body to cool down gradually. Directly pouring water over the head is discouraged as it can cause reverse heatstroke. In case of rain and slippery roads, runners should reduce speed around curves and bridges. Spectators are encouraged to bring raincoats and umbrellas.

The VnExpress Marathon Can Tho 2025 is the first event in the series held in the Mekong Delta, attracting over 9,000 runners nationwide. Beyond its sporting significance, the marathon promotes Can Tho, the heart of the Mekong Delta, showcasing its unique culture, cuisine, and river landscapes. Many runners combine the race with local sightseeing and experiences, integrating sport and tourism.
