Just thought I'd share my first experience of running tubeless for sub 40K around Kent last weekend:
So it didn't seal but did you try dynaplug or anchovies?
I didn't, the cut looked too fat, plus there was a smaller cut very close to the rim which also didn't seal.
Also, didn't do 60k because ^ that happened.
