Weather is one input. The rideability verdict also accounts for soil, terrain, canopy, and drying time.

Why Lake Cunningham Bike Park dries this way

Terrain & soil

Lake Cunningham Bike Park sits in the Bay Area, CA area, on clay soil that holds water over terrain that holds water and dries slowly. With little tree cover, sun and wind get to the dirt fast. Whether it’s worth riding comes down to how that ground sheds and holds water after rain. That’s exactly what Loam tracks, hour by hour.

How these factors affect drying

SoilClay

Dense clay holds moisture and stays slick the longest. It needs the most drying time before it’s worth riding.

CanopyOpen 0%

Little tree cover means full sun and wind, so these trails are among the fastest to rebound after rain.

TerrainHolds water

Water tends to pool and linger here rather than running off, so the surface can stay damp well after the weather clears.
