Track DNA — what the dirt is really like

Sand
Hard-packLoamSand
  • ▸Deep, loose dirt that swallows the front wheel if you back off — carry momentum. Expect soft berms, big roost, and chop/whoops forming by the afternoon motos.
  • ▸Drains fast — often rideable the day after a rain, and it actually rides BEST with some moisture in it.
  • ▸High silt (29%) — this dirt turns to DUST when dry. Expect water trucks, hazy late motos, and pack extra air-filter prep.
  • ▸Flat land — every jump and roller is built, which usually means a faster, more momentum-style track.
  • ▸Wettest months: Jul, Aug, Sep — highest mud/cancellation risk. Prime window: Jun, Aug, Sep.

What do these terms mean? ▾
Sand / Silt / Clay %:
What the topsoil is made of. More sand = looser and faster-draining. More clay = harder, slicker when wet. Silt is the fine dust-maker in between.
Loam:
A balanced sand/silt/clay mix — the tacky, rut-forming dirt riders love.
Blue-groove:
When dry hard-pack gets polished by tires into a shiny dark racing line — grippy for some tires, ice for others.
Drainage class:
USDA’s rating of how fast this ground sheds water — it predicts how soon after rain the track is rideable.
Soil series:
The official USDA name for this exact soil type (like a breed name for dirt).
Relief:
How much the ground rises and falls within the track’s ~1 km square — flat, rolling, or genuinely hilly.
