If you are planning a big public race then you will need to plan it out a bit. A huge part of the planning is making sure that the race makes the news and people hear about it and sign up for it. A great and sure shot way to make sure that people hear about it is to go through the conventional methods of advertising.
Things such as pamphlets, banners, social media marketing, and maybe even a few television ads will do the trick and will get a lot of people to sign up for the race and help you get the publicity you want for the race. The conventional methods of advertising can be really helpful and are a reliable source of publicity, but you should look at the various free marketing options you have available to yourself before going ahead with the traditional method of marketing.
A good way to understand how you can take advantage of free marketing strategies is by knowing who your audience is supposed to be. The type of race or run you are hoping to pull off can give you a pretty good idea of what you could go to gain people’s attention. For example, if the race is a fun run then you know that you want parents and children to join in to it. This means that you can go to a local church or go to local schools in the area and ask the priest in the church or principle of the school to make an announcement and inform the children and their parents about the event. Similarly if it is for a charity, then you can contact the regular donors to have them participate. Social media is also important and pictures of 5k race medals & awards online would help publicize the event.
