Race Details
- What: The Hurtwood 50 starts from the lovely town of Dorking, and follows the Greensand Way into the forested Surrey Hills, a famous Area of Outstanding Natural Beauty. This race route is a ‘lollipop’ - essentially an out and back, with a 5 mile loop off the Greensand Way before starting the return journey. The race takes you up and over Leith Hill, Holmbury Hill and Pitch Hill on a well marked, easy to follow trail through the woodlands, ridgelines and valleys of this area that is collectively known as The Hurtwood. The loop at the western end of these hills takes you off the Greensand Way for a short time before re-joining to make your way back over the 3 hills and to the Finish.
- Cut Off: The race overall cut off is 7.30pm, giving circa 10 hours to complete. This makes it suitable for fast walkers and first time Ultra runners. (darkness usually comes around 4.45pm, meaning the last 3 hours will be by headtorch if taking the full 10 hrs - the signs are reflective...)
