I have a competition that is a three day trip for my mare to get there and I am really worried if she will be okay, any tips to make her comfortable during the trip?

Use Proper and comfortable boots, you can wrap the tail <3
Do not use a tail bandage. Tail wrap only. The bandage will cut off circulation and the tail will die
I always travel mine in bandages - I use a 'pillow' bandage underneath the actual bandages and then wrap quite firm. This helps keep swelling out of their legs when travelling for long periods of time and can't move around very much
Make sure you have enough water for her as well as food. Stop often to check up on her. If possible walk her at stops and reload again. Only do that if it will be safe for both you and the horse.
