Ballpark, 35-40 psi. Don't go softer unless you're using tubeless tyres,
otherwise you risk pinch flats. If the surface is mainly hard packed, then
go harder, but given you're on mud and grass I'd guess you need as much
grip as you can get.
With tubeless tyres some of the serious racers will go below 30psi on
really slippery going, but the softer the tyre the more work you'll do,
and in a race that matters. If you go much harder than 40 you'll really
struggle for grip in greasy corners.
