As the title asks - how does anyone do it? This morning, all I wanted to do was 3 laps of a 3 mile loop at an easy pace - absolute hell! Every 30 seconds there's a Dog sprinting up to you and trying to jump up your leg! Then there's the little ones that run at your feet and you have to try very hard not to kick or trip over them, then there's the big ones that just stand there blocking your path, forcing you to dive into the bushes to avoid running them down, then there's the super speedy ones that unexpectedly bolt round the corner just as you approach, and worst of all the useless owner who just stands there saying "Don't worry he only wants to play".
If I tried to actually run some intervals on a trail I fear that I would be killed! Dunno how anyone can manage it.
