At the top of Highwood Hill, Mill Hill, A young lady got to the top and stopped at the traffic lights. This is a steep hill, and just toppled over still attached to her bike, rolled over onto her back with her bike now on top of her as if she was riding upside down. I know how embarrasing these moments are and fortunately she was unhurt apart from her pride as there were a few cars waiting at the lights behind her, but it did look quite spectacular.
