I left out the following sentences. Could you please check them? Thank you.

2. In their backpacks they have packed extra clothes, food and water for the two-day competition. I can see the finishing line in the background (on or in the top left-hand side of the picture)
3. The first boy on the left is wearing a two-colour (two-tone?) flowery short-sleeved shirt with a yellow T-shirt under it.
4. He is also wearing black tracksuit bottoms with a white stripe on (in?) each side and a white-and-red bandanna on his forehead.
