Honestly, the fire pits at these races aren’t exactly the burning skin-melting infernos that I imagined them to be (for obvious reasons). But you still need to get over ‘em.
Best way to train: Picnic table jumps. Develop your explosive power with plyometrics. To be included in your runs at random intervals – I like the rule “any time you see a picnic table do 5 box jumps.” In the weight room – squat jumps. These will also develop your explosive power and challenge your conditioning to help not only with the fire pit, but the entire race.
