Staying in Lincoln city

Im going to be staying in Lincoln city for a week and would like to ride some trails. I dont want to drive for hours to gt to a trail thats less than 15 miles long. Can someone help me locate some trails 1 - 1.5 hours from lincoln city? I would be willing to drive a little longer if there was a long trail(35+ miles-5000+ ft climbing) I have permission form the Mrs. to take a whole day. If I can't find suitable trails I'll have to ride the road, and that doesn't seem acceptable to me. Any help would be greatly appreciated, and if your ever in northern utah, I can help you find and take you on all the best trails.
