Due to work and family commitments, it looks as though I won’t be able to race any cyclocross in November at all. Essentially ending my cyclocross season. There is however a 6 hour endurance mountain bike race I am considering at the end of November. I would be halfway through cyclocross specialty at that point of my last cyclocross race in late October and would have 5 weeks until the endurance race. The course is a relatively flat 10 mile loop of singletrack with a few short punchy climbs that I would ideally do 6-7 times within the allotted time.
Would I be best served doing 4 weeks of a rebuild or switching over to 4 weeks of Cross-Country Marathon MTB Specialty? The 5th week would be a rest/taper week.
