Bike Leg Nutrition Practice Ride

Session Overview

The bike leg in triathlon is your primary fuelling window — it is the only stage where eating solid food is practical, and where poor nutrition choices will cost you on the run. This 2-hour structured ride is designed to simulate race-day conditions and let you test and refine your nutrition strategy before the pressure of a real event.

What You'll Need

• Road or tri bike
• 2 bidons — one plain water, one with electrolyte drink
• Your planned race-day nutrition: gels, chews, bars or rice cakes
• GPS or bike computer to track time intervals
• A watch alarm set to ring every 20 minutes

Warm-Up (15 minutes)

15 minutes easy spinning at Zone 1, RPE 3-4. Use this time to check your nutrition is accessible, your bottles are secure, and your alarms are set. Begin sipping your electrolyte drink from the first minute — do not wait until you are thirsty to start hydrating.

Main Set

The goal of this session is nutrition practice, not intense training. Maintain Zone 2 to Zone 3 pace (RPE 5-7) while systematically consuming your race-day nutrition at planned intervals. When your watch alarm rings every 20 minutes, consume nutrition as planned.

• Minutes 15-35 (Zone 2): First intake at minute 15 — gel or chews, 150ml electrolyte drink
• Minutes 35-75 (Zone 2-3): Build effort slightly; second intake at minute 35 — solid food option (rice cake or bar)
• Minutes 75-95 (Zone 3): Harder sustained effort to simulate race pace; third intake at minute 75 — gel and water
• Minutes 95-105 (Zone 2): Recovery period; fourth intake at minute 95 — electrolyte drink only

Cool-Down (15 minutes)

15 minutes easy spinning at Zone 1. Make notes about what worked: what sat well in your stomach, what was too sweet, what was hard to open with one hand at speed. Adjust your race-day nutrition plan accordingly.

Coaching Notes

• Aim for 60-80g carbohydrate per hour — spread across multiple intakes, not consumed all at once
• Test the exact products you plan to use on race day — never experiment with new brands on race morning
• Practise opening gels and packets with one hand while maintaining full control of your bike
• For sprint distance, replicate a 45-minute bike leg with just 2 nutrition intakes
• Note how your stomach feels when you start running — that feedback directly informs your race nutrition plan
