In reply to marky:
Hi Mark, from your profile you're pretty accomplished so I'm not sure why I'm replying, but... It seems to vary quite a bit between people, but also will depend on how much climbing and training you've been doing in the last couple of months, and how much you are used to. I find if I have more than two days consecutive rest I feel clunky and lethargic when I return to climbing. How about considering a full week of normal frequency of climbing, but much easier (active rest), or same difficulty but much less volume so that your body can recover even whilst you're giving it some training stimulus.
