Well - I've started my training season, by letting the dogs free run beside me while on a bike or ATV. Though - they still do have leashes on - as I have to run partially through a neighborhood. My goal is to have the dogs doing 10 mile free runs by October - when I will start to do pull training. That way - by the time the "real" training begins in October/November - they'll have a bit of an aerobic base to work with.

I'm keeping them at a very slow, 4-5 miles per hour - so as not to overwork them. This is just to get their hearts pumping a bit - but keep them below hard working physical levels.
