Of the three disciplines in triathlon, by far the commonest source of anxiety and frustration is the swim. Unless you have swum competitively as a child, swimming is technically the most challenging and the sport in which efficiency (or lack of it!) is the biggest limiter.
Individual swimming lessons for adults are hard to come by and often expensive. Triathlon Club and Swimming Club Masters sessions will often focus predominantly on fitness development with less time devoted to technical development. Adult swimmers may feel intimidated starting in a squad environment but have difficulty finding lessons.
For these reasons, fellow BTF Coach Jennie Jones and I recognised that many adult triathletes were crying out for some specific frontcrawl technique development in a small group low pressure environment. Jennie is a BTF Level 3 coach with many hours of pool and open water experience.
