Only Brennan Jacobs could make me agree to a five-mile fun run. I've had a crush on him ever since I can remember. But this body wasn't made to run. The training is grueling, the other runners are mean, and every time I see Brennan I'm hot and sweaty, and not in a good way. But I'm determined to finish, no matter what the cost. She's smart, she's funny, and she may just be running away with my heart.
