Here’s a 20-week open water training program designed specifically for time-based training without pool sessions. This program could help you gradually increase your endurance, strength, and confidence in open water. Distances are built by time, so you can adapt based on the conditions of your open water training location.

Program Overview:

• Duration: 20 weeks

• Training Days: 3-4 per week

• Focus Areas: Time-based endurance, open water techniques, sighting, pacing, and acclimatization to variable conditions (for example current, wind chop and so forth)

 

Water Safety and Additional Tips:

Your safety in the water is ultimately your responsibility. This training program is offered to provide guidance and coaching, but the decision to enter the water is entirely yours and yours alone. Taking on the challenge of open water swimming is a personal choice, and with that choice comes the responsibility to assess the conditions, your own readiness, and any risks involved. We’re here to support you in your journey, but the commitment to stay safe remains in your hands.

• Always swim with a swim buddy or in groups. 

• It is highly recommended to swim with a swim flotation device/buoy.  A swim flotation device/buoy are brightly coloured, making swimmers more visible to boats and other watercraft but also provide a flotation aid, which swimmers can hold onto if they need a rest or encounter an emergency.

• Sun Protection: Cover yourself with plenty of suncream and ensure you are hydrated and rehydrate during your exercise.

• Acclimatization: Swim in different conditions (cold, waves, currents) to be prepared for race day.

• Nutrition & Hydration: Keep yourself hydrated and fuelled with sport nutrition drinks.

• Mental Focus: Visualize the swim, practice breathing techniques for calmness, and set small goals for each session.

• Recovery: Take care of your muscles with stretching, hydration, and balanced nutrition, especially as distances increase.

Practice drafting (if swimming with others), sighting techniques, and maintaining pace in choppy water. Include short sprints to simulate race starts and turns.

4. Taper Swim (45-50 min in final week):

Keep this swim easy and focus on relaxation, rhythm, and technique as you prepare for your final swim.
