~ 8am coming onto Waterloo Bridge on the IMAX side. No one else involved. Can't imagine she was traveling that fast, but clearly she came down pretty hard and hit her head. Conscious, but she really wasn't in a good way (bleeding from ear).
Praise to the fellow cyclists and passers-by that were so quick to help out, and calmly and efficiently aided in the situation. Stayed until an ambulance arrived.
If you ever need a reminder of the importance of a helmet then this was it. Really shaken tbh... Really hope she's okay :(
