Fun Run for human trafficking

I've never done a fund-raiser run, but I'm planning on one for 6/4. Our church youth group is sponsoring it to raise money to aid victims of human trafficking. Funds will go to "Sower of Seeds" ministry.  I plan to run at least 50K (31.2 miles). If 20 of you pledge $1 per mile, that would be enough money to rescue a girl and support her for 3 months. Can I count on you? For details, send me a note or go to http://www.wellspringdfw.org/fun-run-june-4/
