We are in the midst of our third annual St. Jude Radiothon and decided to put the focus on kids for the next couple of days. The kids at St. Jude are all amazing, but this country is full of other amazing and inspirational kids, like Kayla Montgomery. Three years ago, Montgomery was a budding soccer star until she was diagnosed with Multiple Sclerosis, more commonly known as MS. As a result, Montgomery gave up soccer and joined the cross country team at her high school in North Carolina.

The nature of Montgomery's MS condition allows her to run at speeds that cause other runners pain, but the 18-year-old doesn't feel the pain, which gives her a unique advantage in cross country running and she has become one of the best runners in the nation.

The downside is that while Montgomery does not feel the pain while in motion, at the end of the race when she stops running, her legs completely collapse under her and her coach has to be there to catch her.

Montgomery refuses to let MS get in her way, which is why she deserves a designation of "amazing kid" and her story should inspire others, especially kids fighting disease. Not all of these kids may be able to run, but they can certainly be inspired to overcome obstacles. Watch Montgomery's story below.
