Here is a picture of one of the participants. He was one of the few Westerners participating and I really enjoyed seeing that many Thai people participating, originating from all over the country!
The start of my category in the streets of Nathon near the pier. It was quite a big group all divided in age groups and male/female categories and the five first finishers got cash prices in each age group and male/female category.
Just before the quarter marathon start, the half marathon runners got going about 15 minutes before us.
