The Course


The swim will be a 750m clockwise loop of Stanborough’s north lake. 

For the sprint distance, you will complete 1 lap and for the standard, you will complete 2 laps. 

We expect wetsuits to be optional, provided the water is warm enough. However, on the occasion the water is particuarly warm, wetsuits will not be allowed, in which case announcements will be made on this website, ATW’s website and on social media. 


The route will be fully signed and marshalled, so there is no need to worry about going wrong on the course. 

We make sure you only have one thing to worry about: how fast you’re going! 

There are two mandatory and marshalled ‘foot-down’ points on the course which will be detailed further in the event info and briefing on the morning of the race. 



The route will be fully signed and marshalled, so once again there is no worry about going wrong. 

The course is on hard, compacted ground with short cut grass, so despite being a trail run, is a fast course. There is one short climb towards the end of each lap. 

Because the course is contained within such a small area, it is very spectator friendly.
