I don’t have it to hand but there is an ACF document online that has a host of exercises - I think it’s from one of the units in their SW region.
It’s also fairly easy to change exercises around, take a look at the Blue or Bronze ones and see how they could be made harder or adapted to what you have.
For example not enough tyres and planks to have cadets cross the shark infested custard? Get them to build a rope line to transport a bucket of shark bite antedote across. That sort of thing.
