The problem
Why most runners fail pacing
You feel smooth early. You hit halfway thinking everything is under control. Then the cost of going a little too fast starts to show.
I was on pace until 30K.
Feel "on pace" at halfway
Lose control after 30K
Get caught out by wind, elevation, and fatigue
The shift
Pace is not constant. Effort is.
A smart race plan does not tell you to hold the same pace from start to finish. It tells you how to stay controlled when the course changes, when the wind shifts, and when fatigue starts to build.
That means easing off when the race gets expensive, holding steady when others overreach, and pushing when it actually counts.

Proof
Same fitness. Different outcome.
Two runners can start with the same goal and the same fitness. The difference is how they distribute effort across the race.
I was on pace until 30K.
| Strategy | First Half | Last 10K | Finish |
|---|---|---|---|
| Naive pacing | Slightly too fast | Fade hard | Miss target by 6-10 min* |
| PaceMaker plan | Controlled | Stay stable | Finish on target |
Same runner. Same course. Different outcome.
*Illustrative example. Actual time impact varies by course, weather, and execution.
Execution
Don't just plan your race. Execute it.
Your plan does not stay on a screen. Export it as a Garmin workout and follow it during the race, right from your watch.
Know when to slow down before the damage is done
Know when to hold steady and trust the plan
Know when to push because the race is finally asking for it
Like having a pacing coach on your wrist.
From goal to race day
How it works
The overview below keeps the marketing story simple. In the live planner, you still move through Step 1: Race Details and Step 2: Plan Inputs before generating the plan and exporting it to Garmin.
Step 01
Race Details
Start with your target time and race date so the planner knows what you are preparing for.
Step 02
Plan Inputs
Upload your route, confirm the conditions, and give the planner the context it needs.
Step 03
Generate your plan
Build the pacing guidance that fits your course, conditions, and target.
Step 04
Export to Garmin
Take the plan onto your watch for race-day execution.
Supported races
Start faster with a supported race
Choose a known course to preload the route, then add your future planning date and target time before generating the plan.

PaceMaker keeps the live planner on the homepage. The full route upload, weather inputs, and pacing workspace hydrate on the client without changing the launch-page positioning above.

Don't leave your race to guesswork
If you already know your goal, the next step is simple: build the plan you can actually trust when the race gets hard.
