Longboarding is riding on a longboard. Longboards vary in shape and size. Compared to skateboards, longboards are more stable, and have more traction and durability due to larger wheel size and lower wheel durometers. Generally, a skateboard comes in between 28-34 inches long and 7-10 inches wide, while a longboard has a length of 35-60 inches and a width of 9-10 inches. Many longboards use trucks (axles) that have different geometric parameters than skateboards. There are a variety of longboard disciplines, and types of longboards. Longboarding has competitive races down hill where riders can reach speeds exceeding 60 mph (97 km/h). The wider turning radius of longboards, as well as their ability to coast long distances make them more suitable for cruising and commuting on streets than regular skateboards.
