Wake up at 6am. Breakfast at 7am. Today we face a long, hard climb, but visually stunning. Open moorland progressing into high altitude desert. Lunch at Lava Tower (4,600m/15,100ft). Descended to Baranco camp at 4000m/13,100ft). Today we begin to notice the effects of altitude sickness. Nausea, fatigue, diarrhoea. It rained solidly all afternoon as well, so we’re soaked through. Pretty miserable afternoon. First mobile phone signal though, so happy to get messages from home.
