Summitflow Pace for Duathlon · Sprint

5 km opening run

A high-intensity start. Pacing strategy for the sprint opening run.

20 km bike

Power-based threshold work. Sweet-spot pace dominates the short distance.

2.5 km sprint finish

Maximum intensity on heavy legs. Heavy-legs sprinting, trained.

Brick focus

Brick workouts dominate the peak phase. Keeping bike and run close together is essential.

VO2max work

Over the sprint distance, your upper threshold is what counts. VO2max intervals in the peak weeks.

7-day mini taper

A short taper for the short distance. Volume down 50 %, sharpness up.

Grounded in sports science

Polarised 80/20

80% of your training in low zones (Z1/Z2), 20% in high zones (Z4/Z5+). The most effective approach to endurance performance — backed by Seiler (2010) and Stöggl & Sperlich (2014).

Block periodisation

4-week blocks: Build → Build → Peak → Recovery. A systematic increase in load all the way to race day, through the Base, Build, Peak and Taper phases.

Individual zones

Training zones calculated with Coggan Classic (Z1–Z7) from your FTP, HRmax and threshold pace. No guesswork — precise targets for every session.
