I know this is basic stuff but I can't find where I am having a problem routing from a 3750 switch through the router to the Internet. Could someone look at the config and see where I have screwed up?
I have no access list that would stop it.
I can ping from a host on the 172.16.100.0 network to the 10.10.0.0 network but not to the outside world.

Your default route on the router is set to 192.168.100.254. That tells me you have another router you are going through to get to the Internet. Does that router have a route back to the 172.16.0.0 / 16 network? If you can get on that router try and ping some of the networks on the inside. If you cannot then it is a route that needs to be added on that router.

Very perceptive, that was exactly where the problem was I found it right after I posted. Thanks for your reply.

Never Mind the problem was in a different Router.
