You can't please everybody, if you're making an effort to do the right thing don't worry about it. The second guy sounded like he was trying to be helpful, though I wouldn't heed his advice.

That trail is somewhat narrow, crowded, and exceptionally bumpy thanks to tree roots though, so be careful. I think the reactions may stem from jaded joggers who get sick of the three-inch clearance pass from some less considerate cyclists than yourself. I used to run in that area up to 4 times a week.
