(Portland, OR)  --  Runners in this weekend's Portlandathon race will be lending a helping hand to those struggling with homelessness and addiction.  Race organizers say they've chosen the Union Gospel Mission as their charity of choice for Sunday's event.  Portlandathon includes a full and half marathon along with courses for a 5-mile run and a 4-mile river run/walk.  The marathon course is a qualifier for the Boston marathon.
