Backyard Ultra de Langstraat

The Tanis Backyard Ultra Run takes place in late October at TLV de Langstraat's clubhouse on Drunenseweg in Waalwijk, North Brabant. The adult race begins at 10:00 a.m., with participants completing a 6.7 km loop each hour. The race can continue for a maximum of 24 hours. The course follows the forest surrounding the clubhouse, bringing runners back to the same point between loops. The format is straightforward: begin a loop on the hour, complete it in time for the next start, and continue until one runner remains. TLV de Langstraat, the organizer, is hosting the third edition of this event. A youth race is also offered, featuring 3.35 km loops and a 12-hour duration.
