I have a great reason for running 1/2 marathons & 5K's. I run them in memory of someone or sometimes a few people who have passed on or people who are struggling with something in their life. For each person I am running for, I carry a special coin or token or even stone with a message on it in my running belt. While I am running, I think about all the struggles these people have had to endure and it keeps me motivated to run in their memory. After the run, I pass the coin or stone onto a family member of that person or that person themselves to keep with them and help ease the pain. Maybe they will keep it in their pocket or purse during difficult times and it will help them get through some tough times.
