Hi, great idea to get a group together, it always helps to train as a group. With regards to Total Immersion it is actually very suited to open water and triathlon swimming perhaps more so than pool swimming with lots of attention given to efficiency and energy saving. The technique focussed workshops are designed to teach adults, particularly novice triathletes, open water swimmers and swimmers who have found their swimming has reached a plateau. But don’t take my word for it check out the testimonials from swimmers who have done a workshop: http://www.totalimmersionsa.co.za/testimonials.html
