Short Sharp Turbo: 30-Minute Power Session

Session Overview

For the days when a full 90-minute bike session isn’t happening but you don’t want to skip training altogether, this 30-minute turbo session packs a genuine training stimulus into a short window through short, hard power intervals. It’s aimed at intermediate riders who already have a base of turbo experience and know their approximate FTP or hard-effort RPE.

What You’ll Need

• Turbo trainer, set up and warmed up (smart trainer with power reading is ideal but not essential)
• A fan — this session gets hot fast with no airflow to cool you
• Water bottle within reach — you won’t have time to stop and get one mid-session
• A way to track effort: power meter, heart rate monitor, or RPE if neither is available

Warm-Up (5 minutes)

Easy spinning for 3 minutes, then 2 minutes building gradually to just below threshold effort, including 2-3 short 10-second spin-ups to open the legs before the main set starts.

Main Set

Eight short, hard efforts with equal recovery — the whole point of this session is intensity, not volume, so resist the urge to pace efforts conservatively.

• 8 x 1 minute at RPE 8-9 (hard, at or just above your threshold power), with 1 minute easy spin recovery between each
• Aim for consistent power or effort across all 8 reps rather than fading through the set
• Optional harder variation: reduce recovery to 45 seconds once 8 x 1 minute at full recovery feels manageable

Cool-Down (5 minutes)

Easy spinning, gradually dropping cadence and resistance, until your heart rate settles back toward normal. Don’t skip this even though the session is already short — stopping abruptly after hard efforts is harder on recovery than it seems.

Coaching Notes

• Common mistake: treating the first couple of reps as a warm-up and going too easy — with only 8 reps total, an easy start means you’re not getting the training stimulus you came for
• Scaling down: drop to 6 reps or extend recovery to 90 seconds if you’re newer to structured intervals
• Scaling up: once 8 x 1 minute feels comfortable, progress to 10 x 1 minute or shorten recovery, not both at once
• This session works well the day after a long ride or the day before a rest day — it’s short enough not to compromise recovery while still adding a genuine intensity stimulus
