Help - is this possible?

[Trethew]

I'm going on holiday in January and want to do a hike up a volcano. Info says 16km over 5-6 hrs in high temps.

I'm 2 stone overweight, active (gardening) but completely unfit and I hate sport. How do I prepare, or is it a lost cause?

oh ... and forgot to say, I'm in my sixties

Get some comfy, supportive shoes and start walking.
How long could you walk for? Start with that, then go a bit further every time.
Fine to start off on pavements, but think about going on some untarmaced paths to get ysed to walking on rough paths.

You've got 6 months. Yes it's possible.

Do you have any hills you can walk up? Walk up hills whenever possible.

Where there's a Will there's a Way.
Why do you want to hike up so bad?

Why? It's the only way to get to the top and see the view

It's the trip of a lifetime - galapagos - and I want to get every ounce I can out of it. I'm unlikely ever to do anything like this again, and I don't want to be left at the bottom while my children walk up

Thanks all for your advice, and encouragement

Walk, walk, walk.

Hire a tread mill for some cardio as healthy heart will be important at that height and heat

If you have the money I would suggest going to a small gym, explaining what you want to do & working with a personal trainer. If they are decent they would know how to plan it. I say this as the one I go to trains people for passing work fitness assessments, doing charity treks (walking & running) etc The trainer there would love this!
