GR20 in 8 days

Doing the GR20 in 8 days means going twice as fast as planned to get from Calenzana to Conca, so the time needed to do the GR20 is estimated at 16 days! Corsica’s best-known trail was originally designed to be done in 16 days, so you’ll be doubling up on the stages set out in the topoguide, and sleeping in one refuge out of two.

Every day, you’ll come across a refuge halfway through the day to refuel. The GR20 in itself is a physical challenge, but doing the GR20 in 8 days is a real sporting challenge, requiring both material and physical preparation! Are you planning to do the GR20 in 2024? Here are some tips on how to do it in 8 days.

The stages of the GR20 in 8 days

Here you will find a list of all the stages of the GR20. The table below gives you an example of a simple breakdown of the GR20, which is in no way obligatory. You can also take into account the variants, in particular the one that avoids Matalza at the end of the route. Note that if you set out to double the stages, it’s because you either don’t have much holiday or have a sporting objective (and the training that goes with it).

The walking time estimates we give you below are calculated for a classic hiker: depending on your physical condition, you should normally go faster. If you want to cover twice as much distance per day, you won’t necessarily be walking twice as much

Refuges for eating, refuges for sleeping

Here is a list of all the refuges on the GR20. If you want to do it in 8 days, you’ll come across 3 huts a day: the one you leave in the morning, the one you come across halfway along the route (normally for a lunch break) and the hut where you sleep in the evening.

An example of the list of equipment taken by a couple for their GR20 in 8 days

Not only will you have to be a little more sporty than the average, but you’ll also have to travel lighter to go twice as fast, with a lighter equipment list! Doing the GR20 in 8 days is no sporting feat, but it is a real challenge, and one that will be very complicated to achieve if you’re carrying 20 kg on your back! Besides, there’s no point in taking too much equipment, as you’ll be on the trail half as long as the others.
