With Danny U and Tristan. Danny led odds, I led evens. The 2nd pitch was most sustained. The crux moves of the climb however are pulling the roof on pitch one and the tips corner on pitch 4. Pitch 5 of Jupiter, although rated 5.10d as well, was not near as difficult in comparison. Would be foolish not to combine that pitch into the equation when climbing Challenger. Excellent trad route with zero pro bolts. Good for the warmest of RR days. Quick, easy and clean rap.
