First and foremost, congratulations! You are an inspiration. I have one flight of stair knees at this point in my life. More than that, and my right knee starts locking up. I can walk flat paths, even inclines, but stairs and my knees don’t get along.
As for the people who are so OFFENDED that Ragen is walking a marathon, I’ll bet a year’s salary that they wouldn’t be offended if she was thin and walking a marathon. They’d be telling her to go for it.
Third, as to “Fitness Circle Jerk” and their ilk, they are more committed to being jerks than to fitness. If they were really so committed to fitness, they would be talking about their particular exercise routines, what electrolyte drink was the best, things of that nature, not hating on people they don’t even know.
