Yousuli Performance Hub The lab and race-day cockpit
for triathlon coaching.

Most athletes plateau because they're leaving efficiency on the table — levers that don't show up in watts, pace logs, or weekly volume. Yousuli surfaces them. Turns them into race-day strategy.

Why Yousuli exists

Efficiency is the lever most platforms miss.

Watts, pace, and Load only get you so far. Most athletes plateau not because they can't push more — but because they're leaving free seconds and watts on the table in technique, position, fueling, and race-day execution.

Those gains are invisible at first glance. They live in calculators, in technique observations, in equipment audits, in race-execution analysis. That's what we surface — and what we turn into action.

How it works

Four pillars. One platform.

Yousuli is built around four areas where coaches can move the needle — and where most other platforms either don't go, or stop short.

01

Performance analytics &
efficiency levers

The analytical depth coaches actually want — surfaced in plain English. Calculators, metric history with regression detection, technique assessments, lab tests, sport-specific deep dives.

Includes: 36+ calculators (CSS, FTP, CdA, swim DPS, body comp), metric history, lactate analyzer, VO2Master metabolic test, run/swim/bike deep-dive analytics.
02

Race execution

Pre-race planning to post-race learning, end-to-end. The race plan is built once, simulated, validated for feasibility, and then reflected on afterward to feed the next cycle.

Includes: race planning wizard, power-to-finish simulator, goal-feasibility check, race readiness, post-race recap form.
03

Technique &
equipment

The qualitative half of performance, made structured. Technique observations for swim and run; equipment changelogs for bike, shoes, wetsuit, kit.

Includes: tech swim/run assessments, EO SwimBETTER force vectors, swim force entry, bike setup history, gear changelogs.
04

Coach business operations

The infrastructure for coaches running their roster inside Yousuli rather than spreadsheets — multi-team, assistant-coach hierarchy, subscription lifecycle, macrocycle templates.

Includes: teams, assistant coaches, premium grants, billing lifecycle, macrocycle templates that deploy to a roster.
Where we fit

Yousuli sits alongside your training calendar — not instead of it.
The schedule lives where you put it. The understanding lives in Yousuli.

Athletes upload their workouts (FIT or TCX) — Yousuli enriches them with calculator-driven insights, technique flags, and race-context analysis. The training calendar itself stays wherever your coach already runs it.

Who it's for

Built for serious coaching work.

Not a general-purpose endurance app. Built specifically for coaches doing performance work, and for athletes paying for that level of analysis.

Triathlon coaches

Running 5–50 athletes, doing serious performance analysis. The full platform. Multi-team, assistant coaches, macrocycle templates.

Self-coached premium athletes

Want lab-grade analysis without a coach? Pay for premium access and use the same calculators, race plans, and analytics a coach would.
