I did it before covid, when I was in Fort William in August. It was not that hard, but last bit was challenging, I was my my wife too, not a lot of training, having only done Etna before. It is easier coming back, as you go through the food and water, so the backpack is lighter. We started at 9-10 in the morning and we were back at 17.00. Nice, but now, as I approach 50, I wonder if I can still do it again? I may go for the Welsh one next 1085M, or the Snowdon next, I think is only 900M+ next year.
