2021 is the second edition of the DNF Challenge – Backyard Ultra Israel. The event is a Golden ticket event for Big’s Backyard Ultra in Tennesse, USA.

There are only 100 places open. Our focus is to keep this event a small, familiar meeting, where the trail and ultra runners can meet and compete.

The first edition in 2020 had 43 participants.

In 2021 we expect to reach the 100 participants limit.

The race has a day loop on single trails in the Solelim Forest, and a night loop on dirt roads around the forest.

The record is 29 loops, by Ofir Vardi. The assist in 2020 went to Haim Malki.
