A week of content

Straight from the factory's content calendar — what actually goes out for this app.

The jelly-leg feeling, explained

The first few minutes off the bike your legs feel wooden. A brick workout — bike then run, back to back — moves that surprise off race day and onto a random Thursday. 🚴→🏃

“45 minutes in the pool, easy.”

No pace charts, no heart-rate zones to decode. TriAI plans by time — a duration and a plain-language effort. Swim easy for 45. That's the whole instruction. 🏊

The thing I wanted from a tri app: a coach that changes the plan, not just answers questions

Told it I was wrecked and short on time this week. It didn't just reply — it turned Thursday's ride into a rest day and dropped the week 20%, with an undo. First one that edits the plan instead of lecturing me. r/triathlon

Building up to the half distance

Half distance · 1.9k swim / 90k bike / 21.1k run. Pick the date, answer four questions, and it builds the weeks back from race day. 🏁

Push today's workout to your wrist

Tap once and today's session lands on your Apple Watch as a real structured workout — warm-up, intervals, cool-down — tapping you through each step. Leave the phone at home. ⌚

For first-timers dreading the open-water swim — what actually helped me

The lake is the leg everyone dreads. What's really different from the pool, how to sight, and the in-water reset for when your chest goes tight. Wrote up the plain version, no hype. r/Swimming

Doing less, on purpose, before race day

Taper week feels wrong — you cut volume right when you're fittest, and that's the point. Miss a day and there's no streak yelling at you; it just says “here's today.” 🏊🚴🏃
