You should have some base miles before beginning this plan. Ideally, you've been on the bike 8+ hours per week for at least 8 weeks. You can start this plan at any time during the season. You may notice more or less improvement depending on what you have done in the few months prior to starting this plan. Nonetheless, this plan will stress and improve all the physiological systems needed for success in cyclocross racing.
The plan also assumes that you are fresh and ready to start hard training. This is best achieved with a week off or easy week before you start the plan. This plan requires 10-12hrs per week with most of the longer rides on the weekend. It is suitable for a rider with a normal work schedule, but may require time on the trainer during the week due to limited daylight. This plan is not limited to any particular level of rider. The time commitment, however, may be a limiter and make it more appropriate for experienced or committed racers. Nonetheless, if this time commitment doesn't represent a large increase over your previous training volume, it may work for you. Finally, if you find yourself deeply fatigued at any point, you can simply take a few easy or rest days and then pick it back up.
This is a relatively easy ride, but longer and slightly more intense than a recovery ride. Primary training GOAL is fat metabolism and time on the bike. Average Power and Normalized Power should be fairly close and in the lower half of Z2. This means that the rides is steady and most of the time you are in low Z2.
30min progressive warm-up
(as if you were warming up for 10-20km TT)
30min TEST EFFORT (monitor power and heart rate)
15mins at Zone 2 and 85-95 rpm
15min cool down
This workout is about skills. This can be done as a cyclocross-specific ride involving corning, dismounts/mounts, bunny hops, braking and other handling elements...OR...as a MTB ride focusing on similar skills in a trail setting.
The point is to spend a concentrated 60-90 minutes working directly on skills. Repetition, repetition, repetition.
Do not worry too much about effort level. Overall, the workout should not be too physically taxing (except as it relates to the skills)
The goal is to move the legs to support RECOVERY. This is NOT a training session, it is more like an easy walk. Limit duration to 1 hr and keep power and heart rate in Zone 1.
All run workouts are optional. most cyclocross races in the USA are pretty limited on running. As a result, it is usually not a significant element to focus on.
However, if your races do have running it can be a good thing to work on.
