The 100K is the emblematic race of Bariloche100. It is a route that is carried out in a “non stop” format and of self-sufficiency between the supply points.
It can be divided into three very defined parts.
Starting from Centro Civico, more ascent and difficulty
The test will begin at dawn on March 14, from Centro Cívico. The start time is stipulated so that night traffic is less and that most of the route and the best landscapes can be enjoyed by day by all participants. It is also safer, since they will be traveling the most difficult routes in daylight.
Every runner who has consciously trained for such a requirement, understanding the difficulty, the slope and the necessary experience. Keep in mind that the average pace to complete the 100k is much tighter than the 80k and due to the difficulty the cuts are going to be STRICT AND “TIGHTER”. For those who feel they are at the limit of that time, we recommend participating in the 80k distance. See in “time cuts” the maximum time to complete the race.
We recommend having done at least two 50k tests and one 70k test previously. The 100k route goes through more technical terrain than usual in this distance, therefore the time of realization and effort is greater.

There will be time cuts in some supply stations where it will not be allowed to continue with the tour after those hours (without exceptions and on time). These cutoff times will be defined by the organization based on both safety and priority.
This time cuts can be changed prior or during the competition due to securiry reasons.
Race time
The maximum time to complete the race will be 24 hours (an average of 13'30"/km).
The route will be communicated the week before the race since it passes through private land that does not allow access outside of the day of the event. GPS track will not be shared.
