Lucas had not been racing, instead he chose to opt-out and had just been watching from the stands.

The barking broke his daydream, and he heard a camper yell "Hellhounds!" and thats when he stood up, changing his bracelet and clasp into a bow and quiver, he drew an arrow, and instantly the arrow went up in flames, eliciting a some envy from a couple of campers around him that hadn't yet seen the bow. 
 
 He scanned the area, waiting for the hounds to break into his view.
