Some female riders do have issues with track days, they can feel overwhelmed and frightened when mixed in with the blokes that's why female only days are a good idea so that female riders don't have Di*khead other halves taking the p**s and putting them off.
If you have the right bike and equipment for a track day then take part if you can.
These events are not about setting fast laps for novices there are about learning. And before i get any posts about slow women riders i know quite a few one being my ex who are very very quick on a bike.
