People from the mathematics and science societies at Trinity College, Cambridge, are launching an online puzzle hunt next week. For those to whom this means something, it very much seems to be in the SUMS/MUMS/mezzacotta style. Expect it to include cultural puzzles, but I'd be surprised if there weren't logic puzzles in there as well. Prizes for teams of up to five, but also, unusually, for solo solvers! You can find out more at https://cph.soc.srcf.net/
if this is of interest.
I'm hoping that this can also go the other way and that people who play in that puzzle hunt can go on to try out for the UK championships, somewhere down the line!
