Lights
New bibshorts
Mud CX tyres
New road rear tyre after slashing a nearly new Ultremo

And that’s ignoring the fact that:
a) The brakes on the singlespeed have been on their last legs for a year
b) I’m not even close to sourcing/being able to afford a (MTB) race bike for next year
c) Tax, MOT and service are due on the car in the next month
d) I’d like to get my friends and family Christmas presents, ideally
e) And keep a roof over my head

Might be time to look at what I can ebay, and take it from there.
