Another motivation for adding another option is to increase participation numbers and ultimately impact your revenue. Every runner you can add to a second race distance will be more profitable as most of your fixed costs are already covered. Examples of this can be adding a shorter distance to an event already established with a longer route. Add a 5k distance to a 10k race. You now have an option for people who may not be ready quite yet for the longer event, but can move up next year. Half marathons can easily add 10k's and so on. As your event grows, you can keep adding to the lineup and create something for just about everyone in your demographic.
Not every event needs to offer more than one distance. The BolderBoulder 10k has over 52,000 runners and 70,000 spectators. It was not always this big of course. The race found its niche and became a great scene that the community has wildly embraced. People come from all over to run this event. Adding the right mix of distances combined with creating an event that becomes woven into the fabric of your community will get you on course for success for years to come.
