Thank you all very much for your comments and feedback! I found it all to be very helpful!
I think I would be ok running the actual race by myself once I got started and am not as worried about that
afterall you are all right, it sounds like there is a lot of support from others and most are very encouraging and friendly. Im more worried about traveling by myself for the event and not having any friends or family there with me to enjoy time with outside of the race (before or after). I am ok traveling by myself, but am concerned about picking the right resort and transportation, and all of that on my own.

I have this fear I'll take the wrong bus or miss it completely or something silly like that! Im not sure I would want to visit the parks by myself? I hope that makes sense because I think independence is important
Im just wondering how much I would enjoy some of the other aspects of the weekend without others to enjoy it with? Of course, you're also right that I do have time to make new friends here too...

Ahh decisions decisions!
