Gladys has a bit of catching up to doOK so the UK's fastest commer is even faster. I managed 5 runs. 3 of which were within 0.02 of a second of my previous best time. One was 9.01 sec @81mph but I did what I set out to do.. I beat the 9 sec mark with a 8.98 @ 83mph on the 1/8 mile strip.. that's 0-83 in under 9 seconds in 201metres! The thing is a beast
