U7 race adult cut-through

Little experiment, we are still having the odd issue with adults getting in the way of riders in the U7 category, I have considered a number of options but I think the best solution is an adult cut-through. This will be from the top to the bottom of the hill (adults miss out the downhill section). Adults can help going up but then cut through off the track to catch up with their rider at the bottom of the hill. This should stop any rider/parent interaction on the faster sections of the course.
I am not going to make it compulsory for adults to take the cut-through as I realise some younger/less confident riders might need help on the way down but please adults if you do continue down, can you be extra careful of riders on the course.
