I gave this to my cousin who ran her first half this year, after a lifetime of struggling with her weight. She now runs all the time and it's a lifestyle for her. She turned 40 this year and I wanted to get her something extra special. I sent it to her and she posted it on Facebook because she loved it so much, and so did her running buddies. It is a beautiful piece and guaranteed to be a great gift. Giving the marathon one to my BFF for her birthday in a few weeks.
