Any event you do should be for you. People react to illness in many different ways; while I would never "not talk about" something like cancer if I was treated and cured, I do tend to plow through things and then get on with it. It's probably the best way your parents can deal with it right now. So, don't take it personally. Looking to others to get kudos for something like a run or a ride just doesn't work. Think about how hard you are working to meet your goals and then reward yourself!
