I get a lot of "Really? You ride a bike? YOU did the MS150 and finished??" Yeah, I do and I did.

I have noticed that a lot of people are negative to you when you are doing something you really love and are happy about. I have started a new career path in my life, and some people have been...less than supportive.

Maybe they are jealous that you are doing something that makes you happy and they are unhappy. Convince them to get a bike and see how they like it.
