It weighs and costs quite a bit more than the 70-300mm, but returns an excellent shot... and if you are running around like you say, coupled with the SONY's built-in Super-SteadyShot (Image Stability)... you would be good to go and not need much more in lenses.
Good Luck and I hope you at least take a look at the glass I have suggested. I really do not feel you will be disappointed.
Well, I finally was able to get a hold of an older Tokina AT-X 840 80-400mm f/4-5.6 (not the II-model, Tokina will not make it for the SONY-mount *there is something just weird about that* ) for my own lens bag. This lightweight has some reach on it (effectively a 120-600mm zoom).
Anyway, it is on the way from Japan and I fully intend to see if it is up to par with other lenses in that class. I don't expect it to be as razor-sharp as the TAMRON 200-500mm f/6.9, but it should be on par with the TAMRON 70-300 f/4-5.6 LD.
Should be here by week's end, I hope. 
With all the new camera's available ... perhaps we need to revisit the WHOLE NEW BAG idea?
