Hey @alwinhumoto , welcome to the community!
Full disclosure, I’m not a coach, but I can say with a fair amount of certainty that it would NOT be recommended to run 2 concurrent plans of different levels. Each plan would have been designed as either a stand-alone or as a supplement to some other sport with the expectation that you would make gains and adaptations as the plan progresses.
If the level you’ve chosen is too easy, and you are looking for a greater challenge then it may be worth switching up the plan and going with a higher level and/or looking at the difference between a 3:1 vs a 2:1 plan.
If these plans are still not meeting your needs, you may want to consider either chatting with a coach (for a fee) or looking at a customized cycling or multi-sport plan (again for a fee).
