Well the thing is the geometry is not going to be the same therefore it won't exactly feel the same. even at the biggest gear you are still running longer crank arms which physically you will have more leverage and the relaxed geometry doesn't have that compact track feel. I honestly can't give full advice as to what your best options are but the best way to learn is to actually do it. Most velodromes have rental bikes so maybe make it out to the track, even if it is far, take a beginner's class and possibly rent a bike if available and see what you think
