General Build is more applicable to XCO. I used it for 2018 XC race season and have it lined up for 2019 as well. Follow that with the Specialty Cross County Olympic to end mid to late race season, assuming you don’t have an “A” race, but rather each race has equal importance. Then mix in Specialty weeks to extend your peak fitness.
If you have an “A” race you want to peak for, adjust your training calendar to have your Specialty to end on your “A” race week.
