Why runners choose RDA

RDA is built for the runner who wants structure, confidence, smart pacing, and the ability to adapt when fitness changes.

  • Know the purpose behind every workout
  • Train at realistic intensities
  • Build confidence instead of second guessing
  • Avoid forcing workouts that do not match your current level

Turn hard work into better race-day execution.

Your plan helps you understand easy running, long run pacing, tempo control, interval effort, and race-specific preparation.

  • Better pacing discipline in workouts and races
  • Clear progression from week to week
  • Smarter recovery placement
  • More confidence when it is time to compete

How RDA compares to popular apps

You may not need another generic training app. You need a plan that understands your current fitness, updates when you improve, and gives practical pace guidance for the real conditions you train in.

Plan updates after a new PRYes — update future workouts from your new fitnessOften limited or app-dependentUsually requires manual coach or athlete edits

Simple upgrade pathCalculator → plan preview → custom monthly plan → performance toolsApp subscription focusedPlatform plus coach or separate plan purchase
Built for runners who want clarity.

RDA is not trying to replace your watch. It gives you the training structure, pacing logic, and performance guidance you can use with any GPS watch, treadmill, track, road, or trail route.

Elite-level structure without the coach price tag

A traditional personal coach can cost hundreds per month. RDA gives you structured monthly guidance, pace targets, plan progression, and performance tools at a fraction of that cost.

Traditional Coaching

Private Run Coach

$200+ /month

High-touch coaching can be valuable, but it is often too expensive for many runners.

  • Personal guidance
  • Often requires back-and-forth scheduling
  • Can cost several times more than RDA
  • Quality depends on the individual coach

Race intelligenceBuild smarter pacing, split targets, and execution strategy so fitness turns into race-day results.

What happens after you set a new PR?

Most runners improve before their plan does. RDA helps close that gap by letting your updated fitness influence your next workouts instead of keeping you locked into outdated paces.

1. Enter your new resultAdd your new PR or benchmark performance after a race, time trial, or fitness test.
2. Update your pace targetsYour easy, long run, threshold, interval, VO₂, and race-specific paces refresh from your new fitness.
3. Adjust future workoutsFuture sessions can move forward with the athlete you are now, not the athlete you were weeks ago.
No wasted momentum.

When your fitness changes, your training should respond. That is one of the biggest differences between RDA and a static PDF plan.

Built by a runner, not just an algorithm

RDA is built from decades of competitive training, coaching insight, and real race execution. The goal is simple: help runners train with more patience, precision, and confidence.

Train with purpose.

Every workout should have a reason. RDA helps separate easy days, long runs, tempo work, intervals, VO₂ max efforts, and race-specific sessions so you stop guessing and start executing.

  • Control intensity instead of racing every workout
  • Build specific fitness for your goal distance
  • Respect recovery so hard days actually work
  • Use pace ranges that match current fitness

Race with discipline.

The best training plan is not just about workouts. It should prepare you to make better decisions when the race gets hard — pacing, patience, fueling, and late-race execution.

  • Better split control
  • Smarter goal pacing
  • More confidence in race-specific workouts
  • A system built from real competitive experience
