Turbo Trainer: Standing Start Sprint Session

Session Overview

Most triathlon bike sessions build sustained power, but the ability to accelerate hard from a near-standstill matters more than you’d think — out of T1, out of a tight corner, or responding to a surge in a draft-legal field. This session trains that explosive standing start specifically, using short maximal efforts with full recovery.

What You’ll Need

• Smart trainer or turbo trainer with a stable, high-resistance mode
• Power meter or smart trainer power reading (optional, but useful for tracking peak watts)
• A firmly anchored bike — standing efforts put more lateral load on your setup than seated riding

Warm-Up (12 minutes)

10 minutes easy spinning building from very light to moderate effort, followed by 3 x 10-second building efforts (not maximal) to prime your legs and confirm your trainer/bike setup feels solid under load.

Main Set

Each rep starts from a near-stop (very low cadence, high resistance) and goes fully maximal for the first few pedal strokes before settling into a hard seated effort. Full recovery between reps is essential — this is a power session, not a conditioning one.

• 8 x 8-second standing maximal starts (from a near-stop, out of the saddle) — 2 minutes easy spinning recovery between each
• 4 x 20-second seated hard efforts immediately following a standing start, to practise transitioning from explosive power into sustained speed — 3 minutes easy spinning recovery between each
• Optional finisher: 2 x 30-second all-out seated efforts at the end, once explosive legs are already fatigued, to simulate a late-race surge — full recovery between

Cool-Down (8 minutes)

Easy spinning at low resistance, gradually decreasing cadence over the final 2 minutes. Follow with light quad and hip flexor stretches once off the bike — standing efforts load these muscles harder than seated riding.

Coaching Notes

• Full recovery between reps is non-negotiable — if you’re still breathing hard when the next effort starts, you’re training fatigue resistance, not explosive power, and the session loses its purpose.
• A common mistake is starting the standing effort already in a hard gear; use a gear you can turn over quickly for the first two pedal strokes, then shift up as speed builds.
• Scale down: reduce to 5-6 reps if this is your first time doing standing-start work, and prioritise smooth mechanics over raw peak power.
• These efforts are genuinely maximal — expect your legs to feel it the next day, and don’t schedule this session immediately before a key long ride or brick.
