Built by serious runners — for serious runners

You give everything.
Your plan should too.

Most serious runners are training off generic plans built for recreational joggers. HARRIER reads real training data — HRV, pace, fitness load — and rebuilds the plan every Monday around your actual race calendar. Built by runners who have competed at the highest level.

Who is HARRIER for?

Built for athletes.
Designed for the coaches behind them.

Two tools, one platform — a serious training app for competitive runners and a full roster dashboard for the coaches who develop them.

For Athletes

A plan that trains like you compete.

Tell HARRIER your goal race. It reads your actual data — HRV, pace, fitness load — and builds a periodized plan around it. Every Monday it rebuilds based on what actually happened the week before. No templates. No recreational defaults.

  • AI-personalized plan rebuilt every Monday
  • Periodized blocks for XC season & track meets
  • HR zones, running power & stride metrics
  • PR tracker & race-day countdown
  • Syncs with Garmin, Coros & Apple Watch
See Pricing
For Coaches

Every runner, one view. Problems caught before they hurt.

HARRIER replaces the spreadsheet and the group chat. See mileage compliance, HRV flags, and fitness trends for every runner on your roster — and push individual workouts without a dozen follow-up messages.

  • Real-time roster compliance & mileage dashboard
  • Automated overtraining early-warning flags
  • XC & track season periodization & taper tools
  • Broadcast workouts with exact pace & HR targets
  • Scales from JV to collegiate rosters

Why HARRIER

Every run is data.
Most plans ignore it.
HARRIER doesn't.

Every athlete generates pace, HRV, and fitness load data every single day. HARRIER reads it and turns it into periodized, race-specific plans — rebuilt every Monday, designed by someone who has competed at the national level.

Activity Trackers
Excellent social features and activity logs. Built for participation, not competition. Silent when you need to know whether to push or pull back three weeks out from a championship.
Records
HARRIER
Reads 90 days of training and prescribes tomorrow's exact session — target pace, HR zone, distance — timed to peak on race day, not some random Tuesday.
Prescribes
Generic Training Plans
Cookie-cutter plans designed in conference rooms. They don't know you raced hard last Saturday, that your HRV dropped 12 points, or what your event actually demands.
Generic
HARRIER AI
Rebuilds every plan every Monday. Bad meet? Adjusts load. HRV dips? Adds a recovery day. Big PR? Raises the ceiling. Built by runners who have competed at the highest level — not a product team.
Adapts
Features

Six things most
training apps
can't do.

01

Peak on race day, not the week before

HARRIER periodizes your season around your actual meet schedule — building load through base and sharpening into a taper that lands exactly when your XC championship or track invitational does.

02

A plan that learns from every workout

Set your goal race and PRs. HARRIER's AI builds a periodized block from your real fitness data and re-runs the algorithm every Monday. Your plan is never more than a week out of date.

03

See every athlete. Spot every problem.

Your whole roster in one view — mileage compliance, fitness trends, recovery flags. Know who's thriving, who's grinding, and who needs a conversation before they get injured mid-season.

04

The early warning your GPS misses

HRV predicts overtraining 10–14 days before your athlete feels it. HARRIER tracks baselines daily and automatically backs off load when a dip signals that recovery, not hard work, is what wins next weekend.

05

Know if this week is building or breaking

Running power, stride efficiency, and ground contact time synthesized into a single Training Efficiency Score. Trending up? Push. Dropping before a big meet? Pull back now.

06

Coaching, not just announcing

DM an individual with a modified session. Broadcast Thursday's track intervals with exact splits attached. Your squad knows what to do — and why — without a group chat turning into chaos.

Why we built this

Built by runners.
Not a product team.

Not a product roadmap. HARRIER came from competing seriously and finding that nothing was built for how serious runners actually train.

Every parameter — periodization, HRV thresholds, taper logic — built by runners who have stood on start lines that matter.

Social platforms
Great for logging. Can't tell you whether today's tempo was a build or a mistake three weeks from your meet.
Load-based tools
Treats an 800m runner like an Ironman athlete. No event-specific taper, no track season structure.
Generic plan apps
Fixed schedules. Can't adapt to a double-meet week, an HRV crash, or a PR that raises the ceiling.
HARRIER
Rebuilds every plan, every Monday — around your data, your race calendar, your body.
Coach View

Your whole team,
one screen.

Compliance, mileage, and fitness for every athlete. Spot who needs attention before it becomes a problem.
