The Cotswold Lakes SUPathlon is a unique challenge that blends stand-up paddleboarding (SUP) with open-water swimming. If you’re considering signing up but feel a little nervous—especially about balancing on a board or swimming in open water—you’re not alone!
This guide will help you:
- Build confidence on a paddleboard
- Train effectively for better SUP and swimming performance
- Handle transitions smoothly on race day
- Feel prepared, excited, and ready to take on the challenge
1. Stand-Up Paddleboarding (SUP) Training Tips
SUP is a fantastic full-body workout, but racing on a board requires more than just balance. Here’s how to improve your paddleboarding skills for the SUPathlon:
Balance & Core Strength
- Start on calm water – Get comfortable standing, moving, and paddling in flat conditions before tackling more dynamic water.
- Engage your core – A strong core helps with stability. Exercises like planks, Russian twists, and single-leg balance drills improve control.
- Bend your knees slightly – This lowers your centre of gravity and makes adjustments easier when the water gets choppy.
Efficient Paddle Strokes
- Use your whole body, not just your arms – Engage your core and legs to drive power into each stroke.
- Keep strokes long and smooth – Short, frantic strokes waste energy; longer, controlled strokes keep you moving efficiently.
- Focus on even paddle pressure – Uneven strokes can make you veer off course, costing you time and effort.
Building SUP Endurance
- Mix steady paddling with short bursts – This helps you adapt to race conditions where you may need to push harder at times.
- Increase session length gradually – Aim for at least 30–45 minutes on the board to build stamina.
- Practice paddling in different conditions – Light wind and small waves can affect balance; training in various conditions will prepare you for race day.

2. Open Water Swimming Tips for Confidence & Performance
Even strong pool swimmers can feel uneasy in open water. Here’s how to get comfortable, swim efficiently, and stay calm on race day.
Get Acclimated to Open Water
- Swim in a lake before race day – The more time you spend in open water, the more comfortable you’ll feel.
- Practice sighting – Unlike pool swimming, you’ll need to lift your head to sight the buoys and stay on course. Try incorporating sighting drills into your training.
- Wear your wetsuit in training – If you’re using one, get used to how it feels in the water. A wetsuit provides buoyancy, but it can feel restrictive if you’re not used to it.
Overcoming Open-Water Nerves
- Start slow and steady – If deep water makes you anxious, begin by floating on your back or treading water to get comfortable.
- Find a rhythm with your breathing – Exhaling underwater fully helps prevent gasping and keeps you relaxed.
- Stay positive – Your mind is your biggest ally. Instead of focusing on fear, remind yourself: "I’ve trained for this, and I’m ready!"
Boosting Swim Performance
- Work on endurance – Include long, steady swims in your training to mimic race conditions.
- Add interval training – Short bursts of faster swimming will build race-day speed and stamina.
- Strengthen your pull – A strong catch and pull phase helps you move efficiently. Try resistance band drills for extra power.
3. Transitioning Smoothly from SUP to Swimming
The paddle-to-swim transition is unique to this event, but with practice, you can make it seamless:

What to Expect
- You’ll secure your board at the designated area before heading straight into the swim.
- Your legs may feel a little wobbly after paddling, so give yourself a moment to adjust before diving in.
Key Transition Tips
- Practice going from standing to swimming – Try stepping off your board into the water in training.
- Do a quick shake-out – Before swimming, loosen your legs and shoulders to ease into the new movement.
- Pace yourself – Don’t rush. It’s better to start swimming at a controlled pace than to go too hard and struggle later.
4. Reassurance for First-Timers: You CAN Do This!

If you’re on the fence about signing up, here’s what you need to know:
- You don’t have to be an expert. This event is about personal achievement and fun, not just competition.
