      Offset Wind Lines

      Metres

      Out and back courses can be offset to separate the Wind Lines. Pick the side of road and distance to offset.

      Wind Shear

      For the best results pick a landscape that would describe the locality of your course. This is used to adjust the wind speeds for wind gradient/shear. This is the slowing of air flow due to surface frictions.

      Starting Speed

      As default your starting speed will be estimated using your performance settings. If you are starting this course from stationary select 'Zero'.

      Course Direction

      Please note reversing the course will cause Strava Segments to be incorrectly marked.
