Race Readiness
See how your recent training measures up to your race goal. The radar brings six areas of fitness together, so you can see where you are strong and what needs work. Pacey explains the evidence behind each area and uses the biggest gap to shape your plan.
The evidence behind your readiness
Your daily metrics, training trends and race course give Pacey the context to explain what to work on next.
Today's Metrics
Readiness, sleep, recovery, body battery and more — the vitals behind each day, in one place. Your latest Garmin data adds context to the readiness read and the training ahead.
Training Trends
See how your running builds over time and how your distance is spread across different paces. Weekly mileage and pace distribution make your training habits easier to spot.
Weekly Mileage
Kilometres per week across a 12-week block.
Kilometres per week, W1 through W12: 19, 22, 25, 28, 25, 31, 33, 30, 36, 38, 36, 22.
Pace Distribution
Where the distance lands across pace ranges — the middle bucket is goal pace.
- Under 5:25/km — 25 km
- 5:25–5:55/km — 41 km
- 5:55–6:25/km, race pace — 41.1 km
- 6:25–6:55/km — 64 km
- Over 6:55/km — 19 km
Race Course
Drop in your race's GPX file and the course joins the board — the route, the climbing and where it arrives. The Pacey coach's read takes the shape of the course into account.

The route and profile draw from the course file.
Pacey coach's read on this course
Most of the route is flat, so the early kilometres give you room to settle into a controlled pace. About half of the climbing comes in the final third, when tired legs have less to spare. Keep some effort in reserve rather than trying to build a large lead early. On the late rise, hold a steady effort and let the pace ease if you need to.
Mostly flat, with much of the climbing late. Save enough effort for the closing rise.
The Big Picture
See what is working and what needs attention. Know where to focus before race day.
Your longer runs show you can cover the distance and run near your target pace. The main question is how much effort that pace costs when you are tired. The late climbing makes it worth practising a controlled start, so you still have something left for the closing kilometres.
You have the endurance for the distance. The next step is holding goal pace with less effort, especially on the late climb.
A full-length easy run shows the distance is within reach. Your longer, quicker sessions add useful practice at keeping the effort going.
Goal pace is there, but the harder efforts still take a lot out of you. The next step is holding that pace with more control, not simply adding more speed.
Practise a controlled effort near goal pace, without starting too hard. Keep the surrounding easy days relaxed so you can absorb the work.

Questions before you start
- What is Pacey?
-
Pacey is a race-readiness companion. It brings Garmin training and recovery data, your race goal and the course together to explain what is working, what needs attention and how to prepare for your next race.
- Do I need a Garmin account?
-
Connect your Garmin account to use your own training data, or explore the demo with sample data. Pacey uses python-garminconnect, an open-source project on GitHub, to load your Garmin data.
- How does race readiness relate to my goal time?
-
Race readiness compares your current fitness and recent activities with the goal time you set. It constantly highlights your strengths, the areas to develop and what to focus on before race day.
- How does the training plan reach Garmin?
-
Pacey shows a training block of up to 26 weeks. You can review the suggested workouts, then sync the current calendar week’s suggested workouts to your Garmin watch.
- Can I upload my own race course for analysis?
-
Yes. You can upload a GPX file to view the route and elevation profile. The Pacey coach will study the route, consider the climbs and where they occur when explaining race preparation.
- How is Pacey different from Garmin Training Readiness?
-
Garmin Training Readiness helps you judge how ready you are to train today. Pacey compares your recent running fitness with the race goal time you choose, highlights areas to develop and uses the biggest gap to shape your training plan. Pacey is an independent product, not an official Garmin service.
- Does Pacey predict my marathon finish time?
-
No. Pacey assesses your readiness against the goal time you set; it does not predict a finish time or guarantee a race result. Your readiness review explains the training evidence and what to work on before race day.
