VO2max 3×10-Minute Outdoor Bike Intervals

Session Overview

Three sustained 10-minute efforts at VO2max intensity raise your aerobic ceiling and race-day bike power. This demanding session is ideal for advanced cyclists and triathletes looking to push their FTP higher during a dedicated build phase.

What You’ll Need

• Road bike or TT bike
• Power meter (recommended) or heart rate monitor
• A flat-to-rolling route with minimal traffic stops
• Two water bottles and a gel or bar for mid-session fuelling

Warm-Up (20 minutes)

Begin with 15 minutes of easy Zone 2 riding, then complete 3×1-minute high-cadence spins (100+ rpm) with 1 minute easy between each. Finish with two 20-second openers at race effort to prime your legs before the hard work begins.

Main Set

Complete 3 intervals of 10 minutes at VO2max intensity — approximately 106–120% of FTP if using power, or RPE 8.5–9 / Zone 5 heart rate. Take 5 full minutes of easy spinning between each interval.

• Interval 1 — 10 minutes at 110% FTP / RPE 8.5 / Zone 5 HR
• Recovery — 5 minutes easy spin (Zone 1)
• Interval 2 — 10 minutes, aim to match Interval 1 power output
• Recovery — 5 minutes easy spin (Zone 1)
• Interval 3 — 10 minutes, give everything you have remaining

Cool-Down (15 minutes)

Spin home at easy Zone 1 pace for 15 minutes with a high cadence (85–90 rpm) to flush the legs. Never stop immediately after the final interval — keep the pedals turning.

Coaching Notes

• Maintain a controlled, even effort across each interval — avoid spiking power at the start and fading
• If you can’t complete Interval 3, reduce it to 7 minutes and build to 10 over future sessions
• Easier: 3×8 minutes with 5 minutes rest. Harder: reduce rest periods to 3 minutes
• Limit this session to once per week during a build phase — adequate recovery between sessions is essential
