My mother's favourite comment is "Is that wise?"
meaning that she doesn't think that I should be doing it. With the added, unspoken comment "at your age" 
My ex' favourite comment is "I did the GNR" Only he forgets to add, "once, 30 years ago." Doubt if he could run a bath now although he subscribes to all the men's fitness mags
and faffs around in a gym - allegedly
My off-spring are great.
No 2 Child gets out the spatula (a la Run, Fat Boy, Run) and whacks me on the bum whenever I go out - according to him, he's helping with my training
No matter what I'm doing though, he always says "Good luck" (aahh, sweet).
No 1 Child thinks I'm mad, but in a nice "proud of mum" way.
Due to injury, my running will probably be limited to 10k distances, so I was toying with the idea of (thinking about!) moving to tri's instead. When they'd all picked themselves up from the floor, where they'd fallen, laughing..................
TBH, doesn't matter to me what they think, whatever I do, I do for myself
