After the glider section, you can use a mushroom to reach the ramp.
This shortcut is possible shroomless by releasing a mini turbo before the grass and hopping to the ramp.
On the final turn, you can use a mushroom to cross the grass and make a tighter turn.
Strategies
Due to the lack of item shortcuts, Shy Guy Falls is a running track, so pick this track when ahead.
Power items can be used on the final two shortcuts to get ahead.
If you have a Lightning, you can use it at the second set in order to target shock people on their gliders and prevent them from taking the ending shortcuts.
Bob-ombs can be placed at the second turn, the top path after the glider, and the ramp shortcut to impede other players.
