For Rusziona's race you'll see these abilities in your vehicle interface:
- [spell=398225]
- [spell=401260]
- [spell=401261]
For my best attempts, I did this:
There's nothing mentioned for the "Jump" keybind (Spacebar by default), but using it followed by [spell=398225] leads to faster starts compared to only gliding forward + Dashing. I was using a second Dash as soon as available and then tried to avoid touching the gale wind behind the last ring in the canyon because you'll waste several seconds while losing control from being catapulted upwards.
To have my cooldown ready near the gates, I won't use another Dash while getting closer to Blackrock Mountain. I use the boost of another gale wind and grab the green Vigor sphere. Because being too fast within the mountain's winding corridors (IMHO the most tricky part of this race with many chances to ruin your timing), for the only time in the whole race I'm using [spell=401260] close to the gates to slow down completely and immediately Dash with [spell=398225] (without touching the ground) to have a nice pace to get me through the mountain. When you feel safe, you can use another Dash inside but make sure to have [spell=398225] ready for the exit.
The rest of the race is all about using the gale winds and grabbing the available Vigor spheres to Dash on cooldown with one exception: When you temporarily leave the Ruins of Thaurissian and enter the Flame Crest area, there is a tight S-curve. You don't want to be too fast when going in, so keep your [spell=398225] for the end of this short passage.
