First may I offer my sympathy to Jill and I am glad she is OK and secondly my next door neighbours are very keen cyclists and do a lot of road cycling, time trials, road races and so on. Last week the lady of the house was cycling in a group of five near Alston when a football was kicked into the road and went under her front wheels causing a very nasty fall. She had to be taken by ambulance to hospital. The poor lady has many cuts and bruises to her head and upper body with quite a number of stitches in her head. Her husband showed me her damaged helmet (and it was pretty damaged) and he is of the opinion that it saved her from very serious injury.
So my helmet is going on every time.
