Triathlon Recovery Nutrition: Post-Workout Fueling

Optimal recovery nutrition requires consuming carbohydrates and protein within 30-60 minutes after training—typically 0.8-1.2g carbs/kg plus 0.3g protein/kg body weight.

What you eat after training determines how well you recover for tomorrow's session. This guide covers exactly what, when, and how much to eat post-workout.

Why Recovery Nutrition Matters

What Happens During Training

Training depletes:

• Muscle glycogen (stored carbs)
• Fluids and electrolytes
• Damages muscle fibers
• Increases cortisol

What Recovery Nutrition Does

Proper post-workout nutrition:

• Replenishes glycogen stores
• Provides protein for muscle repair
• Rehydrates the body
• Reduces muscle breakdown
• Prepares you for next session

The Recovery Window

Timing Matters

The "window" concept:

• 30-60 minutes post-workout: Most receptive
• 2 hours post-workout: Still beneficial
• Beyond 2 hours: Reduced but not zero benefit

When timing matters most:

• Multiple sessions per day
• Training again within 8 hours
• High-volume training blocks
• Competition periods

When timing matters less:

• Single daily session
• 24+ hours until next hard session
• Off-season training

Recovery Nutrition Targets

Carbohydrates

Target: 0.8-1.2g per kg body weight

Higher end for:

• Very long or intense sessions
• Training again within 8 hours
• Glycogen-depleting workouts

Protein

Target: 0.25-0.4g per kg body weight

Standard recommendation: 20-30g protein

The Carb:Protein Ratio

Ideal ratio: 3:1 to 4:1 (carbs:protein)

Example for 70kg athlete:

• Carbs: 70-85g
• Protein: 20-25g
• Ratio: ~3.5:1

Best Recovery Foods

Quick Recovery Options

When time/appetite is limited:

Recovery Meals

Within 1-2 hours:

Smoothie Recipe

High-recovery smoothie:

1 banana (25g carbs)
1 cup berries (15g carbs)
1 cup milk (12g carbs)
1 scoop protein powder (25g protein)
1 tbsp honey (17g carbs)
Optional: Handful of oats

Total: ~70g carbs, 30g protein

Recovery by Workout Type

After Easy Sessions

Low-intensity, <60 min:

• Normal meal timing okay
• No special recovery needed
• Regular balanced eating

After Moderate Sessions

Moderate intensity, 60-90 min:

• Snack within 30-60 min
• Full meal within 2 hours
• Follow general guidelines

After Hard Sessions

High intensity, 60-120 min:

• Recovery nutrition immediately
• Full targets for carbs and protein
• Rehydrate aggressively

After Very Long Sessions

>2 hours duration:

• Start eating immediately
• Multiple recovery "doses"
• Continue eating for several hours
• Extra attention to protein

Rehydration

Fluid Replacement

Calculate needs:

• Weigh before and after
• Drink 150% of weight lost
• Spread over 2-4 hours

Example:

• Lost 1.5kg during training
• Drink 2.25 liters (1.5 × 1.5)
• Over 2-4 hours post-workout

Sodium for Retention

Why sodium matters:

• Helps retain fluid
• Replaces sweat losses
• Improves rehydration

Sources:

• Sports drinks
• Salty foods
• Salt added to food
• Electrolyte tablets

Recovery Nutrition Timing

Immediate (0-30 min)

Priority: Get something in

• Liquid calories easiest
• Recovery drink or shake
• Chocolate milk
• Quick carbs

Short-term (30-120 min)

Priority: Complete recovery meal

• Solid food
• Full targets for carbs/protein
• Include vegetables if desired
• Normal meal

Extended (2-8 hours)

Priority: Continue fueling

• Regular meals and snacks
• Normal eating patterns
• Keep protein spread throughout

Special Situations

Two-a-Day Training

When training twice:

• Immediate recovery nutrition essential
• Don't skip the window
• Full carb and protein targets
• Continue eating between sessions

Racing/Competition

Post-race:

• Recovery nutrition within 30 min
• Whatever sounds good works
• Don't stress perfection
• Continue eating throughout day

Weight Loss Goals

When trying to lose weight:

• Still prioritize recovery nutrition
• Reduce calories elsewhere
• Recovery supports training quality
• Under-fueling backfires

Before Bed

Late training sessions:

• Still eat recovery nutrition
• May split into two portions
• Include casein protein if possible
• Don't skip because it's late

Common Recovery Nutrition Mistakes

Mistake 1: Skipping Post-Workout

Problem: "Not hungry after training" Result: Poor recovery, compromised next session Fix: Liquid calories, small portions

Mistake 2: Only Protein

Problem: Protein shake only Result: Incomplete glycogen replenishment Fix: Add carbs (banana, fruit, oats)

Mistake 3: Waiting Too Long

Problem: Recovery meal 3+ hours later Result: Missed optimal window Fix: Quick snack immediately, meal later

Mistake 4: Not Enough

Problem: Tiny recovery snack Result: Inadequate recovery Fix: Meet carb and protein targets

Mistake 5: Unhealthy "Rewards"

Problem: Pizza and beer as recovery Result: Poor nutrition quality Fix: Quality foods that support recovery

Creating Your Recovery Plan

Step 1: Know Your Targets

Calculate for your body weight:

• Carbs: ___g (0.8-1.2 × kg)
• Protein: ___g (0.25-0.4 × kg)

Step 2: Plan Quick Options

Have ready:

• Recovery drink at training location
• Quick snack in car/bag
• Easy meal ingredients at home

Step 3: Prepare in Advance

Weekly prep:

• Pre-make smoothie packs
• Cook rice/pasta for the week
• Pre-portion protein sources
• Stock recovery drinks

Step 4: Practice and Adjust

• Note what works
• Adjust if GI issues
• Find foods you enjoy
• Make it sustainable
