Inline Skating Terms You Should Know Before Doing an Inline Marathon: A Guide for Newcomers

Updated: Aug 22

Participating in your first inline marathon is an exhilarating experience, but it can also be a bit overwhelming if you’re new to the sport. Whether you’re inspired by the buzz around the NorthShore Inline Marathon or just looking to challenge yourself, understanding the terminology used in the inline skating community will help you feel more prepared and confident on race day. Below is a comprehensive guide to key terms every newcomer should know before hitting the road. Here's an alphabetical list of inline skating terms that we sometimes use.


# -

  • 3WD: When an inline skate has three wheels. Three wheels make a skate lighter due to less wheels, bearings and axels. These skates typically have 3x110mm or 3x125mm wheels. 3WD skate set ups don’t distribute vibrations over rough surfaces compared to 4WD set ups.

  • 4WD:  When an inline skate has four wheels. Four wheel set ups have more grip and roll over rough surfaces with less vibration. 4WD set ups are heavier than 3WD set ups. 


A -

  • Aero Position: A skating posture that minimizes wind resistance, typically achieved by lowering the back and angling the body forward.

  • Aggressive Skating: A style focused on performing tricks, jumps, and grinds, often using specially designed skates with reinforced frames.

  • Axle: The rod that passes through the wheel and attaches it to the frame.


B -

  • Bearings: Small metal components inside each wheel that allow them to spin smoothly; high-quality bearings reduce friction and increase speed.

  • Bearing Spacer: Bearing spacers fit between the two bearings that sit on either side of the wheel core. Bearing spacers come in various shapes, the most popular is the 8mm UFO spacer. These spacers prevent the bearings from binding when the wheel axel is tight.
