Heart Break Hill Duathlon?

I thought about something today and decided to ask my friends, family, and church members what they think.
I was thinking about putting on a benefit duathlon for our church building. There is only 1 triathlon and 2 duathlons for all of central NM. Alb and Santa Fe are 2 of the largest cities in NM. Most of the duathlon in NM are raced by people from those two cities and most du's/tri's are at least 4 hrs drive from Alb.
I have friends at the NM Outlaws, NM tri club, Fellowship of Christian Athletes, and the Tri-atomics triathlon teams. They would probably be willing to send out emails to all their members and serious competitors in NM. And if we also put fliers at all the run and bike shops in Alb and Santa Fe at minimum we could get 50-100 racers at $40 per that's $2000-$4000. But I don't know why we wouldn't get more like 75-150 racers. If we decided to put it on in early 08, perhaps late Feb-late March, we could probably get into the SW Challenge series. If we did that I'd be willing to bet we could get between 100-450 competitors. The Jay Benson gets 450 racers every year and it is a rough road with allot of switch backs. It's not very pretty terrain.
We could have the transition area at the Entranosa/344 church property. The run could go up Entransoa and back. The bike could go south on 344, down heart break hill and turn around right before highway 14. An absolutely beautiful and challenging ride. Not very much traffic. No major intersections to worry about. And heart break hill is famous in this area among cyclists and multi-sport athletes!
Another great thing about a benefit duathlon is it could possibly get some people to come visit my church or be a great way to reach out to believers or non-believers alike. I could put out church fliers in the race packets. Mark or one of our elders could give a pre-race prayer. It could be a fun way to reach out to the community and also a great tool to help get funding for building our church.
*The hardest thing with duathlons is usually getting enough volunteers to hand out bottles filled with gator aid for the bike leg and cups of gator aid for the run leg. But since it's for the church I bet we'd have more than enough volunteers from our members.

*I would need to see if we could get enough sponsors for enough $ up front to purchase enough gator aid to be handed out on the bike and run legs to every competitor, water bottles for each competitor on the bike leg, small paper cups for the run leg, 26 medals for top 3 males and top 3 females in each age group, 6 plaques: 3 for top three overall male and 3 for top three overall females.

*I would need to find out where to purchase insurance for a duathlon and how much it would cost.

*I would need to see what it takes to become USAT sanctioned race, and if it is even worth it.

So what do you think? Please leave feed back with your opinions. All opinions positive and negative would be appreciated. I don't know anything about putting on a multi-sport race, but I'll do anything to spread Gods word and to support our local multi-sport athletes!
