You can personalize a gift in many ways. Writing a special note to give with the gift is always a good place to start. You might also want to have the gift monogrammed. Have your recipient's name or initials sewn into apparel or engraved on a water bottle or picture frame. Gifts that you make yourself are a great opportunity for personalization. For example, you could put together a framed photo collage of your weekend at a race together. Or, purchase a gift related to an inside story or joke between the two of you. Give the gift of an experience rather than something tangible. You could make him a fancy breakfast for his birthday with his favorite foods, or get him a gift certificate for a massage that he can use after a marathon.
