If I may explain ....
The UK 200mph Speed Record Club, administered for the enthusiast body the Speed Record Club, acknowledges those who have set speed records at or above 200 mph. These will all be two way record average speeds, as laid down by a UK governing body and achieved within the UK. These records are for water and one, two wheel, three or four wheel land vehicles. There are sixteen (16) members of this exclusive UK club who now have purple hats. The first member was the late Donald Campbell in 1955. [There is no gender differentiation.]
The UK200+ Club, administered by Straightliners, acknowledges all who run above the 'magic' 200 speed, although for most these may not be speed records, but they could be standing mile speeds.
Jo Stevens has ridden a two way average of 211.045 mph but this was set on a day in 2012 when the class record was achieved at 231.780 mph. Her fastest standing mile run is 243.5 mph (2012). Jo claims to be in retirement at the present time.
