Three sports, one load picture.
Swim, bike and run stress the same athlete. Matter combines them into one readiness view per triathlete, across a whole squad, and adapts the week when the picture changes.

“Can my 70.3 athlete handle the big bike block starting Monday?”
Not as written. His combined ACWR across all three disciplines is 1.5 — the bike alone looks fine at 1.2, which is why this is easy to miss. Swim volume climbed 30% the same fortnight and his HRV has been flat-to-down for six days. I would hold the block a week and cut swim to two sessions, or start it at 80% and reassess Thursday. Want me to draft both versions?

Built for Triathlon coaches
Every feature designed around the challenges you face daily.
Load that crosses disciplines
Single-sport tools miss the athlete whose bike looks fine because the swim is what climbed. Matter totals the athlete, not the sport.
Squads, not just individuals
Built to triage thirty triathletes at once rather than opening thirty calendars one at a time.
Structured sessions out to their devices
Bike sessions export to Zwift as .zwo, and intervals.icu syncs plans out and completions back.
Taper without guessing
HRV, strain and sleep trends tracked through the taper across all three disciplines, so the peak is a decision rather than a hope.
Strength work in the same picture
Gym sessions count toward load too. Force-plate and VBT data can flow in alongside the endurance work.
Coach keeps the call
Matter drafts the adjustment and shows the evidence behind it. Nothing reaches an athlete until you say so.
