Found it!

I finally found a triathlon to replace the one I originally wanted to do! http://www.uswts.com/wa/welcome.htm

It's perfect -- still an all women event, it supports a cause I can get behind, and it's not until September, which means I still have ample time to get ready! The distances for the Super Sprint are pretty short, so I don't think it will be a huge problem. Yipeee!!! I signed up for it today!!
