Starting plan with A race in 5 weeks

Have just completed one full round of base, build, specialty and am set for a holiday/rest week over the next 7 days. Once I’m back, I then have a B race, C race and my A race (2 day road race with three stages in).

Do I return and start build to have a mixture of everything in or go specialty? Plan builder says Build and that’s what I’ve gone for- but just wanted to see what people thought.

I’ll be racing cross amongst this all too but they’re all C races to be honest till later in the year anyway.
