Day 5 - Day 4 of climbing from third cave to kibo

Tough day today, finally realizing the difficulty of the challenge. We covered around 11 km but gained 850 meters in altitude. 

All of us had headaches and joe the worst. The first time he has suffered so far. 

We arrived at Kibo hut at 4750 m after three hours of walking through barren landscape full of lava bombs. (huge bolders ejected during the eruption which created Kilimanjaro) 

All suffering from headaches and tired, the exertion of the climb was tiring due to the thin air. 

Expecting a very cold night before our summit attempt tomorrow. 

Today's experience had knocked confidence levels a little re our ability to get to the top.
