Winch launches may look sudden and high G, but you soon get used to them. Mrs Mechta's grandaughter had her first when she was six, and she loved it!
The initial acceleration is to some extent related to the wind speed. If there is no wind then the winch must pull you faster to get you airborne. Once up, you will climb at about 45° but it will probably appear steeper. I'm not sure about the G loads, but you accelerate to about 50mph in about six or seven glider lengths. If you are in a K13, which is a common older style training glider, it can seem that it gets pulled straight into the air with barely any ground roll. The more modern gliders tend to take slightly longer.
Best advice is to hang on to your straps (so you have something to grip, and don't obstruct the controls for the instructor). Talk through any concerns with your instructor, and ask him to pre-warn you of what you are likely to see and feel.
'Ridge running' could come on your first flight if you go to somewhere like Sutton Bank and the wind is in the right direction. Few instructors would pass up an opportunity to soar if the conditions are right.
Remember that you are paying though. If you feel at all uncomfortable or get queasy, say so. The instructor wants you to enjoy the flight. Better to have a couple of short flights than one long one if conditions are less than smooth.
If you are concerned by the thought of the initial acceleration of the winch launch but think you might enjoy soaring, a flight at a hill site in the winter may be the answer, as the wind will make both more to your liking.
Enjoy your flight!
