With the test hill, did you all start with peddle or electric power ?
That 1 - in - 4 bit looks horrible ( might try it in a car next year ), so to get close to it must have taken some effort
...ordinarily you are not permitted a "run up" , the rules of the Hill are that it is a standing start only.
After Martins pleading on our behalf, I think the Brooklands staff took pity on us and allowed us a running start - using everything you could manage
It was really hard work, even my 24v didn't get to the top - but it might have if someone fitter/lighter was using it....
.....plus correctly fitting the quick release battery clamp on my left hand battery would have helped
