Other apps show what. We show why.
Did pace drop when it got hot? Did higher cadence actually help? Connect your device or upload files — we track every metric and show how they relate, across your full history.

Why cyclosport
Built to tell you why, not just what.
Five things that make cyclosport feel like a coach who has read every session you have ever done.
02
Your data, not averages.
Generic advice is built on other people's bodies. We compute everything from your own sessions — running, cycling, swimming — so you see what actually works for you.
03
AI Coach — instant workout analysis
Tap any workout for a deep physiological breakdown in seconds: training load, cardiovascular response, pace & power analysis, and one actionable recommendation for your next session.
04
Every workout lands in your inbox
Finish a session and it syncs from your watch on its own — no app to open, nothing to import. Minutes later you get an email with that workout ready to view, with AI Coach analysis.
New
AI Training Plan — built for you, uploaded to your device
Pick a race — swim, bike, run, or triathlon — and a date up to 3 months away. Our coach builds a periodised plan from your current form: TSS, CTL, dominant HR zones, recent volume. If your watch is connected, each workout lands on the device — ready to start with one tap. Every week the plan re-tunes to what you actually did.
The numbers that matter
Metrics that actually tell you something
Eight readouts, each computed from your own sessions.
TSS214
Training Stress Score
Load of one session (duration × intensity) as a single comparable number.
CTL68.4
Chronic Training Load
Your fitness trend — a 42-day rolling average of daily TSS.
ATL61.9
Acute Training Load
Your fatigue right now — a 7-day rolling average of daily TSS.
TSB+6.5
Training Stress Balance
Your form (CTL − ATL). Positive = fresh & race-ready; negative = building.
Cardiac Cost122bpm/km
Heartbeats per km
Drops as aerobic fitness improves — an honest fitness trend.
Efficiency1.34
Speed/power per beat
The flip side of cardiac cost — rising-is-better.
Cardiac Drift3.1%
1st vs 2nd half HR
How much HR rose at similar effort. Over 5% = base too shallow.
SWOLF38.4
Swim Golf
Seconds per length + strokes per length. Speed and technique in one.
// All metrics are computed automatically from your heart rate, pace, power, and cadence data — no manual input.
