San Jose, California (United States of America) - "Santa Teresa King Richard Annual Trail Run". This event is held close to my heart. As a way to honor my father, Richard Limb, I created and named this event after him. My dad has always been a King to me. I remember him sharing stories of his running in Santa Teresa County Park when he was young and the love he had for it. He loved the area so much that as an adult he settled into a home in the Santa Teresa area and lived there for more than 40 years! My dad was a respected English teacher at Leland High School until he retired. In years past, when I initiated this event, my dad would start the runners with a huge smile on his face! This event is my way to celebrate my pride and love for him. Join us in celebrating my father and enjoy a wonderful race with us! www.ultrasignup.com/register.aspx?did=115296
