Our experience of more than 20 years accompanying hikers on the GR20 allows us to make some recommendations. We are often asked about the age: the most important thing is to evaluate its "physiological" age instead of its real age. Observe the signs that can alert you: loss of balance, lower endurance, higher sensitivity to cold and dehydration or reduced cardiovascular capacity... Do not hesitate to do a complete medical check-up to reassure you!

Why do we need to be more cautious after 60-65 years old?
Ageing modifies your physiology and reduces proprioception. The diminution of tonicity, articular and muscular flexbility combine to increase the risk of loss of balance.
The GR20 is really demanding and you have to be able to bear the weight of your backpack everyday.
If you are not sure of your capacities, we recommend to divide the trail into two parts (1 week on the Southern part the first year, and 1 week end on the Northern part the next year for example).
