>>2364740It was really good tbf, though I'd say if you're gonna go to Tanzania, have some other stuff planned like safaris or sightseeing and the like - the mountain itself isn't particularly scenic from what I remember (the climb anyway, it looks really cool from the bottom) so might not be worth the trip just for that. Still an amazing experience though and the country is definitely worth visiting, just stick to the touristy areas and it's pretty safe.
I believe we did the machame route but was a while ago now so not too sure. Was 5 days up and 1 down I think and went over the lava cone (secondary peak) on day 4 (?)
I was probably in the worst shape of my life when I did it lel. I did it when I was 16 and I was proper skinnyfat and unfit back then. If you're getting porters to carry most of your stuff then it's not that bad, I'd imagine it's a lot harder if you're carrying everything yourself. Still though, we had a couple of actual fatties in our group and they managed it. It's tiring but the actual climb is basically just an uphill walk with a little bit of scrambling near the top.
Honestly wouldn't worry about being in really great shape, obviously it would make it easier though, especially if you're carrying lots of stuff or doing a harder route. With regards to what the other anon said about altitude, it's not really just a case of being fit - it affects people differently and it's fairly random who will get it badly. From our group of ~30, I think 3 didn't make it to the top, and only one was cause of altitude (other two got the shits), and he was far from the most unfit of the group. Being fit will definitely help but it's not the only factor. I was unfit and only got a slight headache in the mornings from the altitude. We did mount meru the week before to acclimatise though so maybe it would be worse just going straight for kili.
All in all though, great fun and would recommend
