Great run today! 5.2 mi in 42:18 — that's an 8:08/mi pace, right in your easy zone.

My left knee was tight around mile 3.

This looks like carryover from Tuesday's tempo — you pushed pace about 12% above easy. Roll your IT band for 5 min tonight. If it's still there tomorrow we'll swap the long run for a bike day and keep your week on track.

Will do. What's on the schedule tomorrow?

Rest day — you've earned it. Wednesday is 4x800m at 7:15 pace. We're building toward that half marathon PR. 💪

How it works

01

Connect Strava

One tap — Coach Dean reads your full history and knows your fitness baseline from day one.

02

Coach Dean analyzes every run and texts you

Coaching note the moment your run syncs. Ask anything, any time.

03

Train with confidence, not guesswork

Know when to push, when to back off, and why it's working.

Coach Dean catches what your watch doesn't tell you.

Not “great run!” notifications. Actual analysis from your Strava data — the kind that changes what you do next.

After today's run

Left shin has been a bit sore the last two runs — not sharp, just there.

Classic early-stage medial shin stress. Usually means your mileage ramped a bit faster than your bone remodeling can keep up with. Ice it tonight, skip tomorrow's run, and I'll swap it for a pool session or bike day. We'll ease back in over 4–5 days. If it sharpens at all, ping me before you run again.

Injury sounding board

After Wednesday's 5.8mi run · 9:12/mi · 148ft gain

Nice work getting this one in. That said, your last four runs have all landed at moderate effort — 148bpm average today puts you right in the grey zone again. No real easy days, no real hard day. That pattern builds fatigue without building much fitness. Try a genuinely easy 40 min tomorrow and Thursday's workout will land a lot better.

Your 6-week progress check

Your aerobic efficiency is up 9% over the last 6 weeks — you're running the same pace at a meaningfully lower heart rate. That's your base building in real time. Keep the easy days truly easy and this trend will carry you right through your build phase.

After a big training week

Big week — you've logged 43% more than your 4-week average. That's real training stimulus. Keep Friday short and easy so your body can actually absorb it. Fitness built on fresh legs sticks; fitness stacked on top of fatigue tends not to.

Load management

Works alongside the tools you already use

The missing layer between your plan and your potential.

Training without coaching

Apps alone

  • Plan tells you what to do — nothing explains why
  • “Workout Complete” is the only feedback you get
  • Load builds blind — no one flags what's coming
  • Injury questions go to Google

The intelligence layer

Coach Dean

  • Tracks whether training is actually building fitness
  • Tells you when to push and when to back off
  • Explains every run in plain language
  • Flags load patterns before they interrupt training
  • Works alongside Runna, TrainingPeaks, or any plan

Free to start, then $10 / month

Cancel anytime — no friction

Private coach

The gold standard

  • ~ Weekly adaptation — requires a call to change anything
  • ~ Detailed feedback, but often delayed
  • ~ Scheduled calls & email only
  • High friction: schedules, logins, check-ins

$150–300 / month

Watch your fitness build in real time.

Coach Dean tracks the signal beneath the noise — aerobic efficiency, training load, zone distribution — and surfaces it in a dashboard you can actually read. Not raw data. A picture of whether your training is working.

From the athletes

Coach Dean made all the difference in my most recent ultra race. He helped me strategize mileage build, nutrition, apparel, and so much more — and kept me organized and motivated throughout.

I'm training for a half marathon and Coach Dean has truly been so helpful! He's kept me motivated and helped to work in cross training and proper pacing. It feels like I'm talking to an actual coach with a consistent personality.

Frequently asked questions

I already use Runna or TrainingPeaks — do I need Coach Dean?+

Yes — this is actually our most common use case. Runna gives you the plan. Coach Dean gives you the intelligence layer on top of it: a coaching note after every run, load monitoring, and a direct line for training questions. Keep your Runna structure; Coach Dean adds what no app does.

You can upload your plan as a PDF to the dashboard and Coach Dean will reference it directly when giving you feedback. So instead of "you ran 8:45 pace," you get "that was your recovery day — 8:45 with 140bpm HR is exactly right, your legs should feel fresher by Thursday."

Can Coach Dean actually prevent injuries?+

Coach Dean is genuinely good at catching the patterns that precede most running injuries — load spikes, declining aerobic efficiency, grey-zone effort distribution — and flagging them early so you can act conservatively. He's not a physio and can't diagnose anything, but he's the early warning system most runners are missing.

When something does flare up, Coach Dean will prescribe specific rehab exercises for common running injuries — IT band, shin splints, plantar fasciitis, hip flexor tightness — and swap affected sessions for cross-training alternatives (pool running, cycling, elliptical) so your fitness doesn't evaporate while you recover. The goal is to stay in training, not just to rest and hope.

Can Coach Dean help me if I'm not training for a specific race?+

Absolutely — no race on the calendar required. Plenty of Coach Dean's athletes are focused on building consistent mileage, staying healthy through a high-mileage stretch, or returning from injury. If you're coming back from something, Coach Dean will ask about your current status and build your program around staying healthy first, performance second.

If you just want to run more consistently and stop getting hurt every time you ramp up, that's a perfectly complete goal. Coach Dean tracks your load, checks in after every run, and flags patterns before they become injuries.

What type of races can Coach Dean help me prepare for?+
Coach Dean can build training plans for 5Ks all the way up to ultramarathons, including half marathons, full marathons, and trail races. If you're training for a triathlon, he focuses on the run leg — your running program will be dialed in, but for swim and bike you'd want dedicated coaching alongside. Not sure what distance is right for you? Tell Coach Dean where you're at and he'll help you figure it out.
How does Coach Dean know what paces to assign my workouts?+

The best way is to connect Strava during onboarding. Coach Dean pulls your full activity history — recent paces, long run efforts, workout splits — and uses that to build a real picture of your current fitness before your first plan is written. No questionnaire can replace actual data.

If you don't use Strava, Coach Dean asks for a recent race time or your comfortable conversational pace and calculates your training zones from there using established pace formulas (the same ones elite coaches use). As you train and share feedback over text, those zones get refined over time.

Do I need a GPS watch or Strava to use Coach Dean?+

No — all you need is a phone number. Coach Dean works entirely over SMS with no app, account, or device required.

That said, connecting Strava unlocks the best version of Coach Dean. He'll analyze your history to build a sharper plan from day one, and send you coaching feedback within minutes of every run finishing — pace trends, effort level, whether the workout matched the intent. It's the feature testers have found most valuable.

Does Coach Dean build me a training plan?+
Yes, if you need one — Coach Dean will build a plan from scratch based on your goal, current fitness, and schedule. But plan generation is a starting point, not the product. The real value is what happens after every run: coaching notes, load tracking, and real-time adjustments as your training evolves. If you already follow Runna or TrainingPeaks, Coach Dean works alongside it and you skip the plan setup entirely.
How much does Coach Dean cost?+
It's free for the first 7 days — cancel with no penalties. After that, $10/mo on an annual plan or $20/mo month-to-month.
What training philosophy does Coach Dean follow?+
Dean applies evidence-based principles used by elite coaches — polarized 80/20 training (easy runs truly easy, hard days genuinely hard), Lydiard-style aerobic base building before race-specific work, and Jack Daniels VDOT pacing for accurate zone calculation. He also incorporates targeted strength and mobility work — single-leg and hip exercises that keep runners healthy and absorbing load through a full season. The specifics are always adapted to your fitness level, schedule, and goal race.
What happens if I miss a workout or need to take a week off?+
Just tell Coach Dean. Seriously — text him like you'd text a coach. Whether you missed a run, got sick, or needed a mental break, Coach Dean will adjust your upcoming week to account for it and keep you on track toward your goal. Life happens, and a good coach works around it rather than ignoring it.
Are there any special commands I can text Coach Dean?+

Beyond just chatting, a few keywords trigger specific actions:

  • FEEDBACK — send a note directly to the Coach Dean team. Use this to report a bug, share a suggestion, or tell us something Coach Dean got wrong.
  • DASHBOARD — get a link to your training dashboard, where you can see your current week and upcoming schedule.
  • STRAVA CONNECTION — get a link to update your Strava permissions, including adding or removing the coaching notes that appear on each activity.
  • UNSUBSCRIBE — get a link to cancel your subscription at any time.
  • STOP — stop all messages immediately. You'll also receive a link to cancel billing. Text START to resume at any time.

Everything else is just plain conversation — ask questions, report a run, tell Coach Dean your knee hurts. He handles it.

Is my data private?+
Your training data, pace information, and conversations with Coach Dean are used solely to power your coaching experience — nothing else. We don't sell your data or share it with third parties. If you connect Strava, that access is only used to pull your workout history into Coach Dean and optionally add a coaching note to each activity — you control the notes permission during setup. You can request deletion of your data at any time by texting FEEDBACK: Delete my account.
