Got you you piece of crap!
Took me a few tries, came up with a little strategy that allowed me to do it a couple tries afterward.
Basically, I knew that I couldn't handle full speed for long and crashing slows you down so much, so....
First lap:
Run the whole thing perfectly, not too hard.
Second lap:
Still going fast from the first lap, I go up the right wall, make the left, and then STOP myself before I go down to make the little turn into the forest. You stop yourself by pressing in the opposite direction. So I press to the right, and then immediately run again and finish the lap.
Now I'm not going crazy fast, but fast enough that I can still make time and handle the zig zag tree section.
Third lap:
Same as above.
If you crash once with this method, it's over.
After I thought of trying this method, only took me another two tries to get it.
