"The Legends Trail 250 (LT250) is a non-stop race of more than 250 kilometers/155 miles with 7000D+ during winter time through the Ardennes, in the hilly south of Belgium. The race will start on the 21st of February 2020 at 6.00pm. Participants have 60 hours to complete the course, which, depending on the conditions, is covered by snow and ice, or fully wet and muddy underfoot, whilst being concentrated on the difficult navigation and only having 4 checkpoints and being fully self-sufficient in between. In 2020, LT250 will celebrate its 5th edition."
