Due to thunderstorms forcasted further south though none where we were we decided it should probably be a quick trip, so Mick decided to his own shorter trip to Rough chamber I believe and we headed on to Stream end cave and high speed. The low bit in marathon was draining but we got to Stream end cave after 1 hr 40, took some video and high-tailed it back out, completing the trip in 3 hours 30. I was quite tired near the very end that climb up taking strength out of me. Forecast was correct there was no rain so we did not need to rush but I am glad to see I can still get to the back of Mossdale in less than 2 hours.
