GRIM Down South | 8 Miles

Entries are now open for this year's GRIM Challenge for both 4-miles and 8-miles. For nearly 20 years the GRIM Challenge has been a benchmark for 'adventure' running, an inclusive type of wet, muddy trail racing that is as much fun as it is challenging. The original race, now called 'GRIM Down South', is run in the winter over army vehicle testing ground in Aldershot and is known for thick glutinous mud, waist-high water and bone chilling conditions.
