I went to the Climbing Works with Tom yesterday for just such a session. 3 and a half hours of climbing, trying the purple circuit (47 problems ranging from 6b - 7a+). By the end (well, the end for us! Around problem 41) just feeling the holds was an effort, and I was finding it difficult to articulate properly!
Complete power outage was probably achieved around problem 33. So there is my bench mark. Next session I'll do the circuit again (probably in reverse) and hope to get further round before my power fails me.
My weaknesses were very apparent:
- Finger Strength
- Power Endurance
