Campus Vlans Distribution Layer Issue

Hey guys I'm playing around with packet tracer and I decided to do a simple campus network design. I've got a router, l3 core, l3 distribution. and l2 access. I can get my switches on the distribution layer to ping back and forth to the router with default routes. But my host's won't in their vlans. They can only ping vlans on the same distribution switch. Can't even hit the router from the host's. It's like it's not routing the host traffic back to the core. If I enable ospf it all works fine so I know I have a routing issue just trying to understand the issue. I've set ip route 0.0.0.0 0.0.0.0 10.10.0.1 and I also made sure ip routing is enabled. Thanks in advance.
