Friday, Day 6, just after midnight.
Woke at midnight for the final lurch up the mountain. We drank sweet tea and chatted nervously about the rigours ahead of us, each wondering if we had the energy and willpower to get up the mountain. Final adjustments to kit and spirit and we’re off! It had been decided that some of the stronger walkers should be dotted through the party to encourage some of the slower, colder walkers.
The pace is really slow, since some of us are feeling the effects of altitude more than others. After all, Barafu Camp is at 4640m (15,223ft) and the temperature is significantly below zero with a breeze in our faces. We’re all strangely quiet, a nervous act of reflecting on the tiny pool of light before us thrown by the head torches. When I look up I see a snake of light making its way upwards towards the summit, an indistinct margin between the lamps and the stars. Where does one end and the other begin? Breath comes fast and short and I begin to wonder if I should have been less cavalier about abstinence from Diamox. Too late now.
Trudging onwards and upwards interminably through that loose scree, fantastically tiring. I’m kind of glad about the cold though since I burn hot when I walk and this isn’t presently a problem.
Occasionally we meet people already coming down, turning back through sickness or nerves. These dark travellers undermine my confidence and raise questions about endurance. One of these is Umbrella Lady, our not-so-friendly Belgian. I’m too oxygen-starved to decide whether to be gleeful or sad. It could just as easily be me.
Frequently we stop to drink and snack, some people have problems with their liquids freezing in the chill, however I don’t seem to be freezing over, maybe because of the design of my borrowed backpack and my bulk. We thaw these folks out using warm water brought up for the purpose.
Simon, one of our Tanzanian guides on the mountain, starts to show concern for some of the trekkers and the resulting pace and is keen that we should split into two groups. Tom is adamant that we should stick together as a group however. He is right of course. I’d been having some internal mutterings to myself about whether the speed of the slowest would compromise the success or failure of the faster trekkers, and was wondering if selfishness would triumph over the communality of the effort. Such lofty thoughts shouldn’t really be attempted at altitude.

Sunrise over Mawenzi, 26th Sept, 06:04
By and by the sky to the east begins to lighten. With this false dawn comes the real cold of the night, lower than -15C with wind chill. One of our group has had to turn back with breathing difficulties and I’m worried about another. It’s a product of lack of judgement on my part and depletion of oxygen for all of us, so I defer to our guides. Guides who have been to the top maybe 75 times.
When true dawn breaks there is a feeling of hope and optimism, we’re still a long way from Stella but the day is warming and the spirits rise. There may be an end to all of this …
