Thailand marked the one year anniversary of last summer's dramatic cave rescue, in which 13 youth footballers and their coach were saved after spending two weeks trapped in a flooded cavern, by holding a commemorative marathon and biking event in the city of Chiang Rai.

About 4,000 people took part in the activities, which were organized by local authorities with the aim of raising funds to improve conditions at the Tham Luang Cave Complex where the youngsters were trapped.

Nine members of the Wild Boars joined their coach in running the marathon, smiling and posing for photos, while looking notably taller and older since last summer's ordeal that attracted global attention. Those in attendance included government officials, divers, and cave experts who were involved in the rescue mission.

"We were able make this impossible task become possible, and if you ask me, that is how we feel. I think that every staff member, ten thousand people involved, all feel happy to have been part of this situation, and to help 13 children." Former Chiang Rai Governor Narongsak Osatanakorn said in an interview.

Local ethnic women performed in traditional dress at the ceremony for members of the Wild Boars soccer team, when they return to Tham Luang after the marathon.

The team entered the complex on June 23 last year, but soon became trapped by heavy flooding. Divers found the group 10 days later, and rescued them during an operation that began on July 10.
