Neuromuscular Power Sprints: 10-Second Turbo Repeats (30 Min)

Session Overview

Ten-second all-out sprints on the turbo are one of the most underrated sessions in triathlon training. These brief explosions recruit your fast-twitch muscle fibres, improve neuromuscular firing patterns, and teach your legs to produce peak power quickly — giving you the ability to surge past competitors or respond to climbs mid-race without blowing up.

What You’ll Need

• Turbo trainer or smart trainer
• Power meter (recommended — you want to see your peak watts)
• Heart rate monitor (optional for this session — power or RPE is more relevant)
• Fan — these short sprints generate significant heat
• Water bottle

Warm-Up (10 minutes)

10 minutes easy spinning in Zone 2 at around 90 rpm. In the final 3 minutes, perform 3 × 10-second spin-ups (gradually increasing cadence to 110+ rpm) with 30 seconds easy between each. These prime your neuromuscular system for what follows.

Main Set

Every sprint should be 100% — a maximum effort from the moment the interval starts. The 50-second recovery is deliberately long relative to the work interval to allow near-complete recovery so every sprint can be truly maximal.

• Set 1: 10 × (10 sec MAX sprint / 50 sec easy spin) — aim to reach 110+ rpm by the end of each sprint
• 3 minutes easy spinning recovery between sets
• Set 2: 5 × (10 sec MAX sprint / 50 sec easy spin) — maintain the quality from set 1

Cool-Down (5 minutes)

5 minutes very easy spinning at under 100W (or RPE 2), progressively reducing cadence. Your legs may feel heavy — this is normal after peak power work. Avoid the temptation to skip the cool-down; it helps clear metabolic waste from the working muscles.

Coaching Notes

• Start each sprint from around 80 rpm and accelerate hard — don’t pre-wind to a high cadence before the interval begins
• Upper body should stay relaxed — power comes from your legs, not from gripping the bars tightly
• If using a smart trainer, switch to manual resistance mode to avoid the lag in ERG mode during short sprints
• Note your peak power on each sprint — over weeks, you should see your average peak power rise
• Easier version: reduce to 8 × 10 sec in Set 1 and 4 × 10 sec in Set 2. Harder version: add a third set of 5 × 10 sec at the end
