Coach Pacer
Reading your health data
A
I did 18 miles yesterday but I'm pretty beat up. Still doing tempo tomorrow?
That 18-miler showed up in your data — your HRV dropped 14% overnight and resting HR is up 6 bpm.
HRV −14% · HR +6 bpm
Let's swap Tuesday's tempo for an easy 40-min recovery run and push threshold to Thursday. Your fitness is right on track — no need to dig a hole.

That makes sense. What pace should I target on Thursday?

Why Pacely

The missing layer between
your data and your performance.

Every athlete has a GPS watch. Almost none have a coach. Pacely closes that gap — at a fraction of the price.

Generic training apps

  • Static plans that ignore how you actually feel
  • One methodology fits every athlete (it doesn't)
  • No feedback loop when you're overreaching
  • Can't explain the why behind a session
  • Built for runners. Everyone else is an afterthought.
  • $0 in AI coaching, $200+/mo for a human coach

Pacely with Pacer AI

  • Adapts your week based on sleep, HRV, and readiness
  • Your framework: Lydiard, 80/20, Sweet Spot, 5/3/1
  • Flags overtraining before your body sends the bill
  • Plain-language explanations for every session
  • 24+ sports. From 5Ks to Ironmans to OCR.
  • Free plan available. Pro from $9.99/month.

What Pacer does

A coach who never sleeps,
never misses your data.

Real Coaching Conversations

Ask Pacer anything — "Why is my long run pace down?", "Should I race Saturday?" You get a real, data-backed answer. Not a FAQ. Not a generic tip. Your data, your situation.

A
My legs feel heavy. Should I skip today's workout?
Your sleep score was 62 last night and you've got 4 sessions in a row. Do a 20-min walk instead — active recovery, not skip. Tomorrow will be better.

Adaptive Training Plans

Your plan reshapes around your life — illness, travel, a tough week. Pacer adjusts on the fly, not buried in settings.

Health & Recovery Awareness

Sleep, HRV, resting HR, steps — Pacer reads your wearable data and brings it into the coaching conversation automatically.

Goal-Focused Periodization

Sub-3 marathon, first 70.3, podium at a local race — Pacer builds a structured path and holds you honest every week.

Personal Records Tracking

Longest run, fastest 5K, biggest ride — Pacer auto-detects your PRs as you train and celebrates them the way a real coach would.

Train your way

You pick the philosophy.
Pacer builds the plan.

Most apps pick a methodology for you and hide it. Pacely puts you in the driver's seat. Whether you swear by Lydiard base-building or live and die by 80/20 polarized, Pacer coaches in that framework — not around it.

Stack on add-ons: cross-training for injury prevention, extra Zone 2 base work, strides and drills for efficiency, mobility sessions, gym strength, plyometrics, or rucking. Your plan, your stack.
