What preparations do you need to make for the first run of the whole horse?

First of all, you should make sure your physical condition. You can have a physical examination to see if there is any heart problem. There is also the need to train well in advance and accumulate enough running. Book your own hotel in advance, or arrange your itinerary in advance. Then you must rest early the night before, have breakfast the next day, arrive at the venue ahead of time, don't worry, stop if you feel unwell, don't stretch immediately after running, and then go home and have a good rest.
