Peter’s (Race) Pacer 10



Summary

Peter’s (Race) Pacer is a Garmin Connect IQ Data Field which resolves 2 issues for me when I’m running a race:
  • Before the race starts I want to see the current time of the day (well actually I want to see, how long till the race starts?)
  • When I pace races it used to be doing mental math all the way, now this is no longer necessary as you can fully depend on the average pace/speed, because this data field allows to correct the distance at the kilometer / mile marker by simply pressing the LAP button
While the data field’s primary intent is to race races, you can also use it to run laps around the track, just set the lap distance to 400 meters and press the lap button as you cross the line!…

Installation / Configuration

  • Install the Data Field on your watch by clicking download in the Connect IQ store
  • Customize the data field in the Android App or Garmin Express 
    • Manage Apps
    • Select Peter’s (Race) Pacer
    • Click on the button “…”
    • Configure the settings and hit ok.
  • Configure your watch to use the data field:
    • On the clock face click “Start button”
    • Choose the Activity Profile for which you wish to install this data field for (eg Running)
    • Press the down button
    • Choose Activity Settings
    • Choose Data Screens
    • Choose “Screen 1” (or another screen)
    • Layout: click Start button and click the down button until the layout shows only 1 field 
    • When 1 field is selected press the back button
    • Choose field 1 (and click start button)
    • Choose “Connect IQ”
    • Select “Peter’s (Race) Pacer” from the list (hit start button)
    • All done, hit back, back, back, back…


Usage

(All functionality of this datafield uses about 22k, which is way too much for the older Connect IQ devices (only have 16k memory there). To be able to run the field on older devices I’ve stripped items marked with (*cIQ2) from those devices to be able to run it within the 16k memory limit.)


Before starting the race an initial data screen is shown (*cIQ2), this screen shows you the following data:
  • Time of the day
  • Current heart rate (+ zone indication)
  • Configured Settings Summary (Change these settings in Garmin Express or in the Garmin Connect Android App)
    • Target Pace / Target Speed / Target Finish Time 
    • Target Distance: 5k, 10k, 10 miles, half marathon, marathon or custom distance
    • Lap Size in meter
      • 1 k = 1000 meter
      • 1 mile = 1609.304 meter
      • typical length of track = 400 meter
  • Battery Percentage Remaining
  • Gps Signal Strength Indication



When pressing the START button the race timer will start and a new data screen will be shown, this data screen will show you the following information: 
  • top middle configurable field: current heart rate / average pace / average speed / perfect pace / perfect speed
  • left configurable field: average pace / average speed / current heart rate / perfect speed / perfect pace
  • middle configurable field: speed, smooth speed (5s average), smooth speed (10s average), pace, smooth pace (5s average), smooth pace (10s average)
  • time ahead / behind
  • race timer
  • (adjusted) distance covered (see adjusting distance explanation below)
  • estimated time of arrival
Perfect Pace / Perfect Speed
This field recalculates as you run and gives you the pace you need to run to arrive at the finish with 0 seconds behind / ahead (eg if you run a 10k race and want to arrive in 1 hour (avg pace=6:00min/km) and currently you’re at the 7k point in 41:30, which means you’re 30 seconds ahead, then the perfect pace will show the value 6:10 (min/km) as you can run the next 3k 10 seconds slower to still get in time at the finish line

Adjusting the race distance

In a race when you’re next to the race marker press the LAP button, the distance will now be corrected to the nearest lap position (eg 5.08 will correct to 5, 8.8 will correct to 9, …). After pressing the lap button the distance will be adjusted and all averages will be recalculated against this new distance figure.

When you miss a lap marker don’t worry: do not press LAP and go for the next lap marker. 

When you press the LAP marker by mistake you can undo the (last) correction by pressing the LAP button again (within a 30 second window)

Note: Adjusting the distance by pressing the LAP button has no influence on the recorded distance. (When you come home and look on Garmin Connect the distance will be the recorded GPS distance). If you turned off auto-lap you will see where you pressed the lap button and which mile/kilometer marker corresponded with which GPS distance.

Recommendations

  • Test the data field on a training session so you’re used to the layout.
  • Have a second screen with a native data field configuration as a precaution.

Donations

The data field is fully functional without donating. Donations are optional but encouraged from from within the data field with a small encouragement text. If you find Peter’s (Race) Pacer useful and/or Peter’s (Race) Pacer helps you to achieve your goal you can show your appreciation by donating an amount (suggested donation: 5 euro) on my PayPal account

After donation you will receive a donation key on your paypal email address which which will remove the “Like it? Donate!” message from the data field. (this is a manual process, but normally you should receive a key within 24 hours).

    Great feature, but nevertheless due to GPS error I was mislead and almost missed my new PB on my latest marathon race.

    PS, it was not your implementation I used 🙁

    That’s why Peter’s (Race) Pacer is so great, it takes GPS errors completely out of the equation as you can sync your watch with the race distance at each mile/kilometer marker 🙂

    Excellent. The synchronisation with KM markers is just what I had been looking for. Would love to donate, but PayPal requires that I set up an account with them – something that I will not do. Any other way to donate?

    hi John, glad you like my app!
    Alan had a while ago a similar question, I made this page for him http://starttorun.info/about/ If you use this donation button you don’t need to create an account and you can directly use your credit card or visa.

    Thank you! This is what ive been looking for! I will test it today and during 10K race this weekend and donate.
    I usually do it the “manual” way, Put datafield with LAPS, AVERAGE LAP and manual lap every KM. Then AVERAGE LAP will give me correct pace but I still need to calculate how far im behind etc.

    I have a idea for a NEW app, and it should be pretty easy to build based on Peters Race Pacer.

    Its a app for indoor track running (or running some other place you cant use GPS)

    Example: In Oslo, Norway, we have a indoor track which is 546meters one lap.

    Settings for the app should be like “How long is the track?”

    Every time you run a track and press LAP it should calculate distance. DISNTACE = DISTANCE + 546m, or just like 546m * LAPS.

    And one field for last pace. If you run a round in 2:11 it will be 4:00 pace (2:11 for 546meters = 4:00 pace). This is harder for people to calculate on the fly.

    This app would also be pretty usefull for outdoor track running, Since the watch always know that a LAP press = 400m.

    So the app is just like Petes Pacer WITHOUT GPS =)

    Just an idea for a new app! =)

      added it to my todo list, no promises though as I can’t keep up: there’s more inflow than outflow 🙂

      good luck with your upcoming race. 😉

    Peter’s (Race) Pacer totally saved me on the Copenhagen Marathon.

    During the last couple of training runs prior to the race, my Fenix 5x had an issue with the GPS and repeatedly got both pace and distance (and GPS trace) wrong. So on race day I didn’t trust the expensive watch. But with Peter’s (race) Pacer I knew that I could get a reliable lap time every official 1km, and that allowed me to pace myself successfully and beat my PR by over 10 minutes.

    Brilliant tool!
