Create a tshirt design for upcoming high school cross country race

Each year our high school cross country team hosts "The Dale Shephard Invitational Cross Country Race". At this event we sell t-shirts as a fundraiser for the team. We need your help designing this year's t-shirt. Attached are five designs from prior years' t-shirts to give you an idea of what we are looking for. This needs a quick turn around, please. Needs to be done by Saturday. Also, we will provide the school logo.
