Race For Life Basildon is a muddy 5K obstacle event held within Gloucester Park in Basildon, Essex. The start and finish are on grass, with the route remaining within the park boundaries, utilizing a combination of grass and tarmac paths around the lakes. The course is predominantly flat, featuring a few short inclines, meaning the obstacles present as much of a challenge as the running itself. A 3K option is also available, commencing in the morning.
