– on your fitness level
– what you trained before you start the 24 week plan
– on your goals
– on how hard you climb
– if you want to change some workouts of the plan to climbing (maybe the core!?)
it’s a very individual question, but if you want a short answer: if you increase the stress on one side you probably have to reduce it somewhere else. So if the training from the plan is more than you have been doing, you should probably scale back on climbing. But as I wrote above: it depends!
hope that helps!?
