Does anybody know?

I have a friend who own's a local mud racing track and he wants to add a ATV sand drag strip and needs to know about how deep he should build the foundation up, does he need more at the start and less down the track? He wants to get it up and running ASAP because the mud truck racing season is in full swing. Any help would be appreciated.

id say that it should be even all the way.say like 3 to 4 foot deep all the way down the strip. cause like at the sand dunes you dont know how deep the sand is so i guess it wouldnt matter.

it should be deep at the start, then go down in depth. everytime the motor vehicle burns out, it pushes sand all over, so in time, you will lose a lot of sand at the start.
