Brutal at Congo Stream

Pirbright, United Kingdom • 18 Apr 2026

Event Overview

Brutal at Congo Stream features a multi-lap format centered around a 3.3 km to 3.5 km course. Participants have 4 hours to complete as many laps as possible, with the option to participate as a solo runner, in a pair, or as part of a team of up to four people.

Course Details

The route begins on a level grassy area that serves as the event headquarters and provides space for team change-overs and supporters. Most of the course passes through mature mixed woodland. The terrain includes hills, a stream, and marshes. A notable feature of the route is an old trench system that functions similarly to a sunken maze.

The name of the event is derived from Congo Stream, which flows through the property from the neighboring Mazamboni Farm.

  • Pairs Entry: A team of two people handing over between laps.
