If you are still looking, I am the Indy Mini Team Captain for the Children's Tumor Foundation's NF Endurance team. We have 17 charity entries left for the race, and we would be happy to help you get into the Indy Mini.
If you get your entry through us, we offer a pre-race pasta dinner, a booth at the expo in case you need any support during packet pickup, personal fundraising support, and on course coaching.
Also, with our entries there is no registration or transfer fee. Instead, you would get a code that would let you register on the Indy Mini website for free using the "Tracking Code A" option.
Let me know if you would like specific details. You can always check us out on Facebook to get a feel for our team community too. http://facebook.com/nfendurance
