Choose the sport
Choosing the right sport for a charity event is probably the most important thing to do if you want it to be a success. While planning an event of this sort, you must take into account which sports are most popular in the city or country, and thus more likely to attract large crowds. For example, if you are organizing a charity sports event in South Asia, you should probably choose cricket, as the sport is a great crowd-puller in those parts. However, if the event is going to be held in the United States of America, it would be prudent to select a sport like baseball or basketball.
Decide how the money will be raised
Next, you have to decide how you will be using this charity sports event to raise money. Apart from charging spectators for tickets, and taking donations from both players and spectators, you should also request the participation of local businessmen - urge them to get involved in the event and make a healthy contribution.
Find a stadium and players
Before advertising the event, you have to make arrangements for the stadium in which the event will be taking place, and invite the players who are going to be participating in the event. It is recommended that you contact a local sports association, and request their help in this regard. If you are able to convince the management of a sports association about the nobility of your cause, it is likely that they will arrange a stadium for you without charging you anything. Similarly, players might also agree to participate for free if they are convinced by the motivation and reason behind the charity event.
Find sponsors and volunteers
In order to raise more money and cover the expenses of the event, you will need to work hard to find sponsors who are ready to spend their money. Many companies, organisations, and businesses will be willing to advertise their brands through a charity sports event, if you manage to convince them successfully.
It will be very hard for you to organise the event alone; therefore, you should take all the help you can find, from people who are willing to volunteer their funds and services for the noble cause.
