If we do this it will be a fun run/walk type event but I figured it out and we will need at least $2500 in sponsorships just to break even. First there is liability insurance which is around $500. If we preorder 100 t-shirts at $10 each that is around $1000 and there are guaranteed to be additional costs of running the event such as security/safety provided by the police dept., advertising/publicity, creation of a website which allows for online registration, etc that will add up fast. Lots of details that must be worked out and expenses that must be underwritten by sponsors if we are going to make the run/walk profitable and an annual event.
I believe it can be done but I am very nervous and know I will need help. If you are willing to help be on the team to put this thing together and make it a success and/or would like to learn more about becoming an event sponsor, please let me know.
More details will be available soon!
