Competitive swim teams
Youth, masters, and performance squads — technique blocks, stroke refinement, turns and starts, and race-prep sessions built around your training calendar.
Teams & clinics
Swim coaching for squads, teams, and coaches.
Pool technique, open-water preparation, and race-day confidence — delivered by a licensed swimming coach with decades on the deck, not as an add-on to a run or bike programme.
This page covers group and team work — clinics, squad sessions, and coach development. For personal one-on-one endurance coaching, see full coaching or apply here.
Clubs, squads, and coaches who take the water seriously
Triathlon teams & clubs
The swim leg is often the barrier for multisport athletes. Open-water skills, sighting, drafting, race-start practice, and pool progressions that carry into the season’s key events.
School & university programmes
Intensive clinic days or short blocks — structured sessions for groups that need clear feedback and practical drills athletes can use straight away.
Swim coaches
Workshop delivery, observation and feedback days, and mentoring for coaches who want another experienced set of eyes on technique, session design, or open-water programming.
Clinics and squad work — tailored to your group
Formats depend on pool access, group size, and goals. Typical work includes:
Technique clinics
Pool-based sessions focused on stroke mechanics, efficiency, and drills — freestyle for triathlon, or full stroke work for competitive swimmers.
Open-water sessions
Sighting, buoy turns, drafting, wetsuit and race-start practice — building confidence for open-water races and triathlon swim legs.
Squad blocks
Multi-session visits when travel and calendar allow — a concentrated period of coaching embedded in your club’s existing programme.
Coach education
Practical workshops for swim coaches — progressions, feedback cues, and open-water planning from someone licensed through ASCTA and WSCA.

I am Andy Astfalck — Australian national-level swimmer, decades coaching swimming, open-water, and triathlon swim legs in clubs, schools, and international teams. I hold a Master’s in Applied Science (Sport Coaching) from the University of Queensland and am licensed through the Australian Swimming Coaches and Teachers Association and the World Swimming Coaches and Teachers Association.
