I've booked to do the Tour Du Mont Blanc. It's 65 miles, including 6000m of assent over 6 days.
The reviews all say the same thing, an amazing trip but hard going, long days and you need to be really fit.
I am fit, I walked 15 miles yesterday and can run a HM in 2 hours without doing any additional training, but I'm also a woman in her mid 50s, so not fit like a young man. E.g. 19yo DS came on the walk yesterday and I can't keep up with him. I'm feeling very tired today after yesterday's adventure.
So, I'm very fit for my age and sex - Garmin tells me I'm in the top 1% 😆 but is that fit enough?
Also, as someone who lives in East Anglia, how do you train for this? I'm starting to get very cold feet...
