Open water swimming is a key part of many triathlons. Skills are included in pool sessions but there is nothing like getting out there. Sessions in open water are not coached and are managed by external groups.

In 2011 members trained at several venues including:

• Redricks Lake, Sawbridgeworth (www.facebook.com/redrickslakes)
• Histon Lake, Cambridge (http://wildswim.com/histon-lake-cambridge)
• Jesus Green Lido (http://www.everyoneactive.com/tabid/1185/default.aspx)
• Gosfield Lake, Braintree (http://www.gosfieldlake.co.uk/traithlon.html)
• The River Cam at Granchester (http://g.co/maps/nyte7)
• Frinton Beach (http://g.co/maps/azd9d).
