Kids DUs?

Thanks to Kiwanis and OUM we have a great offering of triathlons for kids in the Houston area. Our 9 year old daughter has done 3 so far this season and is really enjoying them.

Unfortunately, we haven't been able to find much in the way of duathlons for our 7 year old daughter. I understand Tri on the Run sponsored one recently but I never saw information on that until right before the race. When we search we are only finding one in La Marque July 17 which happens to be the same day as Shadow Branch Creek tri we planned to do as a family relay. Our daughter really had a heart set on a DU, any suggestions? I'm not finding much in my searches but the TOTR race didn't show up when I searched in the spring so maybe there are more out there I am not finding.
