Glack Attack 7 October 2017

Glack Attack is a 5km obstacle mud run held on Glack Hill, Aberdeenshire.

The course navigates the hill's forests and bogs and is hindered by a mixture of manmade and natural obstacles, not to mention the inevitable inclement weather...

It is a hard earned 5km of running, crawling, paddling and whatever you need to do to survive the attack and get over the finish line!

Glack Attack 2017 is open to everyone 11 years and older

Entry is in the following age categories:

  1. 16+: the full Glack Attack experience!

  1. 11 – 15: the full 5km course (without 4x high risk obstacles) - participating 18+ year old chaperone required

  1. 3 – 10: the Glack Attack mini-run! A short course packed with awesome obstacles designed for young children

Glack Attack Mini-run

The mini-run is designed for the next generation of mud runners. Glack Attack is a family run event so who better to design an obstacle course that young children will love!

The mini-run is for children aged between 3 and 10 years. The low risk obstacles will include hay bales, tree trunk hurdles, ‘muddy puddles’, cargo crawls, balance beams, slides, tunnels and many more.

The Ninja challenge is an optional obstacle at the end of the course, designed to test your ninja skills. Only the elite (or the very lucky!) will succeed!

Individual & Team Entry

You can enter as an individual or as a team of 5 runners.

There will be prizes for the first male and female individuals and first team across the finish line.
