Irulan,
I train hundreds of miles alone on country roads, and no I would not stop to give directions to a stranger for seveal reasons. 1st this stranger might be a preditor who is using that line to lure me into stopping and then try to hurt me and
2nd My training time is very precious to me. I work very hard to carve it out of a very busy schedule of work and parenting.
If I am doing intervals for example and trying to stay in a target heart rate zone, the last thing I need is to stop suddenly.
Now... so you think that I am a bad person....I have stopped to render aid to ladies with car trouble and to fellow riders with mechanical troubles but I personally think that it is rude to bother someone who is training or working out.
