Strength, determination, endurance. Your son has so many amazing qualities. Let him know on his birthday with a birthday card that goes the distance to help him celebrate. A runner has just left the starting line, ready for the race ahead of him. And just like your son, he'll do his best to get to that finish line and take first place. Your continued love and encouragement are expressed in the heartfelt words and wishes, letting your son know how proud you are of him, not just today but every day.
