Problem Solved

For our problem with our two actors riding the horse at the same time. We have thought of an idea where we will have both of them on someone else's shoulders running along a field. Where we will then film from a low angle looking up so that it looks like they are moving as if they are on the horse. Hopefully this will work on our next filming day, which we are planning to do on two days. This is because we are not able to get  our actors to the place where the horse is. Therefore we have decided 2 days so we can get the filming done as quick as possible so we are able to check and edit the clips. On the 7th feb we are hoping to get the horse shots done and then on the 10th feb we are going to get the actors shots done.

Here is our planned storyboards for our new scenes:
