I quit distance running twice before due to knee pain, but now I'm back in business: I'm training for my first full marathon in eight years. (mindbodygreen.com)
I ran my first (and only) full marathon at 55 years old. (going4ward.com)
I am about 4 days away from completing my 1st full marathon and I will have trained 16 weeks for it. (mommyedition.com)
