Backyard Ultra de Langstraat

Backyard Ultra de Langstraat is a backyard-style running event in Waalwijk, Netherlands, organized by TLV de Langstraat. Adults run 6.7 km loops, starting a new round on the regular backyard-ultra rhythm, with the adult race capped at 24 hours. The event is scheduled for a late-October weekend, continuing into the next day. The setup also offers younger runners and walkers their own shorter option: 3.35 km rounds, with the youth race capped at 12 hours. This is the third Tanis Backyard Ultra Run, following an earlier second edition. The format is simple to grasp but challenging to execute: keep completing loops, recover quickly, and line up again until the clock or the limit concludes your participation.
