I think the Speed Bump would really not be that difficult like Roadblock or Detours, I mean think about those speed bumps last seasons like sitting on ice, washing tanks, staying in sauna etc. Those speed bumps are not like solving puzzles, they're just tasks that can be finish in an average or fixed time.
But i'm really worried about G/M's position,,, I'm rooting for them...
I also speculate the Trotters u-turning K/V since the goths were the cause of them being U-turn by cheerleaders in China... It would also be interesting if they U-turn them right in front of their faces!
