in order to travel at 12 m/s (43 km/h or 27 MPH) this lady should be a very experienced and strong cyclist. She will be riding a road racing bicycle and she will be leaning down on the handlebars to keep a very aerodynamic position.
In order to reach 12 m/s on a bicycle you need to exert a great effort and you must be very concentrated on what you are doing, especially under the rain. Both your hands will be on the bars, and close to the brake levers.
Raindrops will reach a terminal velocity which depends on their diameter, and the size of a raindrop does not exceed 5–7 mm in diameter, because any raindrop larger than that will break up in smaller raindrops. The terminal velocity of the largest raindrops is in the range of 20 m/s (70 km/h or 44 MPH)
