Ok this can actually be done in the trail or the full game.
On the very FIRST level within 30 seconds of being dropped onto the track there will be a massive jump about 12 to 16 seconds into the race if you don't hit any of the walls or anything maintain the fast speed you can holding down
or
and you should clear the gap/jump easily with a little over 500m and Boom easy achievement. If you mess up just restart to checkpoint with the
button ! But if you don't hit an walls you should clear the gap easy.
Again this can be done in the trail if you don't have the full game.
Good Luck to All.
Dislike my guide comment below why and I'll add/ change whatever I can to better the achievement Guide.
Thanks Guys!!
