AIA One Billion trail is a part of the AIA One Billion campaign, which aims to engage a billion people to live Healthier, Longer, Better Lives by the year 2030.

AIA would like to invite you to participate in this fundraising trail running event. Teams of 4 competitors must complete the course of approximately 100 kilometres within the time limit of 36 hours and let us take this chance to do something extraordinary that inspires others and, at the same time, help less fortunate others to have a better quality of life through the work of The Thai Red Cross Society.
