It stopped for a few years after 2011 & came back in about 2019, & the past 2 years has been a round of the British Championship.
I was talking to Steve earlier, as he did a bit of work on my bike & I was telling him of my success last week at Leighton (did i mention that? )
Shame it rained all day!
I know for many years it has belonged to the Shuttleworths, not sure if still the same.
