What Training Plan Choose for a XC - Marathon Multi-stage

[cesjimp]

Hi, I am trying to find the best training plan to prepare a XC - marathon with seven days of competition. The Base Phase will be Sweet Spot, but for Build Phase and Specialty Phase, I am not sure what option will be the best. Thanks for your advice.
