I booked a holiday for Christmas / New Year and some days will include some amazing hikes at relative altitude.
I have the option to opt out of the hiking days but would prefer to be able to do them.
So the question is how to boost my fitness level.
I cycle to and from work so have some base level fitness. I am in my 50s and don't do any other real exercise.
Hiking will be between 2,000 - 3,000 metres (highest will be 3,400) and uphill bits as well to get the views.
Any practical ideas to boost my fitness for this much appreciated, especially ones that don't necessarily involve purchasing a gym membership or buying specialist equipment!
