Hydration Tips for Paddle Boarding: A UK SUP Racer’s Performance Guide

A race-ready guide for UK SUP racers

Hydration can decide a race before the first buoy. On the water, you sweat more than you realise. Wind hides heat stress. Cold conditions suppress thirst. By the time you feel dehydrated, performance is already dropping.

Whether you race on inflatable stand-up paddle boards or hard boards, hydration strategy matters just as much as board choice and paddle setup.

Why Hydration Matters More on the Water

Paddle boarding creates steady, full-body heat. Sun reflects off water. Wind dries sweat fast. You lose fluids without noticing.

Even mild dehydration causes:

• slower stroke rate

• early fatigue

• poor balance

• muscle cramps

• reduced power output

For racers paddling long distances on touring or race-style boards, dehydration shows up first in endurance, not speed.

How Much Should You Drink When Paddle Boarding?

There’s no single number, but there is a safe range.

• 400–800 ml per hour

• Increase intake during:

  • warm weather

  • long-distance races

  • high-intensity intervals

UK conditions often feel mild, but wind and cool air still drive fluid loss—especially on open-water routes.

Pre-Paddle Hydration Strategy

Hydration starts before you get on the board.

2–3 hours before paddling

• 500–700 ml water

• Add electrolytes for race sessions

30 minutes before launch

• 200–300 ml

• Avoid heavy chugging

This applies whether you’re paddling an inflatable SUP or a hard SUP.

Hydration During Paddle Boarding

Short sessions (under 60 minutes)

• Small sips every 15–20 minutes

• Water is usually enough in cool conditions

Long sessions or races

• Electrolytes become essential

• Aim for:

  • 500–750 ml per hour

  • steady sipping

For touring-style inflatables such as the Loco Scout Air,
deck bungees make hydration access easy without breaking rhythm.

Water vs Electrolytes for SUP Racing

Water replaces fluid. Electrolytes replace what sweat removes.

Electrolytes help:

• retain fluid

• prevent cramping

• support muscle firing

During races over an hour, plain water alone is rarely enough—especially in windy UK coastal conditions.

Hydration Gear That Works for Racers

Your hydration setup should allow hands-free drinking and stay secure in chop.

Most modern inflatable SUPs include deck storage, but dedicated SUP accessories make hydration safer and easier during long sessions.

Avoid setups that require stopping or destabilise the board.

Hydration for Different Paddle Board Types

Different boards create different hydration demands.

• Inflatable stand-up paddle boards
  Longer sessions, steady pacing, consistent sipping

• Hard SUPs
  Higher intensity, more frequent hydration breaks

• Surf SUPs
  Short bursts, hydrate before and after sessions

• White water paddle boards
  High effort plus cold exposure increases dehydration risk

Matching hydration strategy to board type prevents late-session energy crashes.

Common Hydration Mistakes SUP Racers Make

• Drinking only when thirsty

• Ignoring electrolytes

• Underestimating cold-weather dehydration

• Drinking too much at once

• Skipping post-session fluids

These mistakes affect paddlers across all board categories.

Post-Paddle Rehydration & Recovery

After paddling:

• 500–750 ml fluid within 30 minutes

• Include electrolytes after long or hard sessions

Hydration comes before recovery meals.

Quick Hydration Checklist for Race Day

• Hydrated before arrival

• Electrolytes prepared

• Hydration secured on board

• Sipping plan in place

• Recovery fluids ready

Final Thought

Hydration isn’t about drinking more. It’s about drinking with intent.

UK SUP racers who plan hydration the same way they choose boards, paddles, and race lines stay consistent across the season.
