Ironman Taper Bike — Easy 90-Minute Low-Stress Ride

Session Overview

Your Ironman taper bike keeps your legs sharp without generating fatigue. In the final 10–14 days before an Ironman or 70.3, volume drops significantly — but a handful of well-timed race-pace touches remind your neuromuscular system exactly what race day feels like.

What You’ll Need

• Your race bike (ride the exact bike you’ll race on)
• Power meter or heart rate monitor
• Race nutrition to practise fuelling rhythm
• Quiet roads or turbo trainer for the power efforts

Warm-Up (20 minutes)

20 minutes at Zone 1–2 (55–65% FTP) at 90–95 rpm. Focus on smooth pedal stroke and settling into your aero position. This is movement to get blood flowing, not training.

Main Set

Short, sharp, and intentional. Three race-pace efforts remind your legs what Ironman power feels like; two brief spikes remind your system of higher-end output. Total effort time is under 20 minutes.

• 3 × 5 minutes at Ironman race pace (75–80% FTP): 5 minutes easy between each. RPE 6–7.
• 2 × 1 minute at 85–90% FTP: 3 minutes easy between each. Just a neuromuscular reminder. RPE 7–8.
• Total main set including recoveries: approximately 40 minutes.

Cool-Down (30 minutes)

30 minutes of Zone 1 easy spinning. Use this time to rehearse race-day nutrition rhythm — sip your race drink, eat a gel at the same intervals you plan to race at, and note how your gut responds.

Coaching Notes

• The cardinal taper sin is riding too hard and arriving at race day already fatigued. When in doubt, go easier.
• Ride in your race position — use this as a kit check: tyres, brakes, cleats, nutrition pockets.
• Taper legs often feel odd for the first 20 minutes — do not panic or push harder to compensate.
• Works equally well on a turbo if road conditions are poor — reduce the cool-down to 20 minutes.
• Schedule this ride 3–5 days before race day for maximum race-day freshness.
