What level of fitness/skill are you starting from?
What are your aims?
CX is short, intensive, and technique dependant, therefore I’d say a training needs to match this. The issue is that with one or two races each weekend, Monday and Friday are rest days, leaving only three days to train.
Me, well;
Tuesday is running intervals, short and fast with a small amount of recovery.
Wednesday is club specific CX training, so lots of technique work, say an hours worth, then a 20 minute race intensity mini race.
Thursday will be on the rollers doing two by 20 minutes at a set power level.
If I’m not racing then one longer session at the weekend, (2.5 hours), and one more shorter interval session, (less than 60 minutes).
