ROANOKE, Va. -

Wednesday, volunteers put together supplies for the 17-aid stations that will be set along the route.

Things like cups, trash bags and electrolyte drinks are organized into boxes.

The day before the race they'll be loaded in an u-haul.

"Some places we're lucky and able to do it the day before the night before, but most places we go out at 2:30 in the morning and we put the materials, the table, the tents and all these boxes and the things out," explains Assistant Race Director Molly Bullington,

Organizers say given this is the marathon's 5th year they know what to expect -and that helps.

Everything is going according to schedule.

But, organizers say they could still use nearly 150- more volunteers.

They say the number they have now is fine, but more is always better.
