Is this only for full-distance triathlon?

No. Sprint, Olympic, 70.3, 140.6, and single-sport blocks (swim, bike, run) are all supported. Off-season base blocks too.

Is my Strava data safe?

Yes. We use Strava's official OAuth flow, never store your password, and you can revoke access in one click at any time. Your training data lives in an encrypted database we control.

The triathlon training app

Train with intention. Show up ready.

Q: I already use TrainingPeaks / TrainerRoad / Runna. Why Rift?

Those tools are built for a coach to use on you, or for one sport. Rift is built for the self-coached triathlete who wants a plan grounded in real coaching methodology, built to flex when life shifts, and honest about the numbers.

Q: What happens when the beta ends?

$19/mo or $129/yr at launch. First 500 Founding Members lock in $9/mo for life. We'll tell you before we ask for your card — no surprises.

Only triathlon. Built deeper than any multi-sport app. Adaptive plans calibrated to your fitness numbers, your weekly schedule, and your race calendar.

How it works

From race day, working backwards.

Start with the race

Date, distance, terrain.

Sprint, Olympic, 70.3, 140.6. Rift lays out every week from race day back to today — taper, peak, build, base.

Fit it to your week

Hours, days, equipment.

The time you can actually train. The days that work. The equipment you have. A pro-grade plan that survives Tuesday meetings and Saturday weddings.

Adapts as you go

Show up ready.

Your zones grow as you get faster — Rift catches the drift and prompts you to update. When you miss sessions or need to shift the week, the AI coach helps you rebalance.

The science behind the plans

Most plans are templates. Rift's are calculations — built fresh from your real data, your real schedule, and your real race.

Your real numbers. FTP, threshold paces, and HR zones from your own input — verified by science-backed ranges, not textbook defaults.
Your weekly availability. Five days, three days, one long Saturday — Rift fits the plan to your real schedule.
Your race day, working backwards. Blocks structured base → build → peak → taper so you arrive sharp, not cooked.
Your zones grow with you. Rift watches your actual paces against the plan's targets. When you're consistently outpacing them for several weeks, we catch the drift and prompt you to update — so your zones stay honest as your fitness moves.
Your week, when life happens. Miss Tuesday's intervals? Ask the AI coach to rebalance — it preserves the key sessions of the phase and trims the filler.

Built on the methodologies of Joe Friel, Stephen Seiler, and Matt Fitzgerald — calibrated to you, not to a textbook.

Who's building this

Built by an athlete who got tired of stitching apps together.

Built by Eli Avgi — lifelong hybrid athlete (lifting since 13, ran track in high school), entrepreneur, biohacker, and founder of ReGlow Wellness. Got deep into triathlon last year and immediately ran into the same problem every self-coached athlete has: TrainingPeaks felt like Excel, Garmin Coach was generic, the AI apps over-promised.

So I built what I wished existed — a plan engine grounded in the methodologies of Joe Friel, Stephen Seiler, and Matt Fitzgerald, that actually fits the hours you can train and the calendar you race. Currently in private TestFlight. Opening to the first 500 Founding Members in July 2026.

"Every feature we've shipped came from a workout I screwed up because the old app didn't tell me what I needed."

How is the AI actually useful?

The AI doesn't write your workouts — a calibrated algorithm does. The AI coach reads your recent workouts and answers plain-language questions: why is today hard, what should I drop if I miss a session, am I going into race week tired. It knows your data, not just triathlon in general.
