Today was race day and I took on board all of the advice and I didn’t lose or crash (well other than on the practise lap).
I wasn’t super quick, but my bike handling skills were more than up to the technical course even with cantis.
I did have to play with tyre pressure, but went a bit higher than others, which cut through the mud better with my 95kg on board.
All in all a great days racing and well worth a go. I’d recommend it to anyone.
A huge thank you to all for the advice.
