Hill Climber - S4.E9

The challenge this week is to build a one-man hill climber. The teams will have three attempts to scale a 360ft slope with a 1:2 gradient. The team that makes it to the top the most times wins. If both teams reach the summit only once, car-rallying rules will apply and the first successful attempt - that is, the successful attempt in the earliest of the three rounds - will be the one that counts.
