Slowing down at downhillsThere are two places in this stage where you don't want to approach a downhill at full speed:
1. The downhill after the first big vertical jump on lap 2.
2. Right before the downhill in the second tunnel on lap 2.
This is the ring route that gives the optimal boosts for this stage.
