> I'm looking at setting up a (very!) small business in the South West, providing fitness and endurance training at a slightly higher level than already offered. The sessions will be geared towards those hoping to enter the forces or compete in endurance events such as triathlons or simply those who enjoy a bit of suffering.
I had a friend try to do this exact thing (also based in the SW)... the problem was people who are motivated to perform at high levels are also motivated to train themselves, hence the perceived gap in the market...
As said qualifications are not necessary but getting insurance without might be really hard or expensive. A good log of experience will help.
