Hi CQ, that's why I started taking mine too for time saving but actually they both love it! One will go further so if I'm doing a long run I do two loops and drop the greyhound home before going out again :)
I would also like to say that I have ever been to a rave and certain only not a 10k, blimmin phone!
It's soooo foggy here this morning, met my friend as usual and my hair was soaked when we got back, fringe dripping and the end of my ponytail really wet too, the air is soooo damp.
