This route is super runnable until it suddenly is not! Hot day on the ridge - managed to summit in 3:04, then back down for a 5:37 finish at the TH. My partner TJ accompanied me for safety (if worst came to worst) but did not provide pacing or support outside of making sure someone would notice if I fell off the knife edge.
Boulder field going up to K2 is always a navigational challenge - I feel like being able to move efficiently through there is where all the opportunity is! Was super hot on the descent, but thankfully the single track is PRISTINE and speedy!
