There were medals and t-shirts last 2 times. I'd be surprised if there's no medal.
You can leave a bag at the finish, the start is a 20min walk from the car park/finish so the idea is you just wear a jumper to do the walk then chuck it in a carrier bag. That way the organisers don't have loads of heavy bags to cart back to the finish.
