   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?

   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! =)

   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!

     Thanks for the kind words Tomas. And big congrats on beating your pr! Way To go!

   Hi Peter, thanks for implementing the idea of readjusting the distance run by pressing a button at the distance markers. I suggested this idea to Garmin about 2 years ago, with no reaction whatsoever. I have no ConnectIQ capable watch yet (“only” a FR620) but if I ever will, this app will be mine!

   I also own a FR610 with a footpod, and followed fellrnr’s recommendation to calibrate the footpod, but still found it less accurate than the GPS distance measurement (pace round value).

   Honestly, I sometimes do not believe the accuracy of the mile markers… I’ve seen GPS vs. mile markers off by more than 300 meters during a marathon, and yet the overall distance was accurate by less than than in the finish. Hmmm…

   • Reply Peter Jul 25,2017 07:09

     hi Harald,
     I couldn’t miss the app anymore. 🙂
     I don’t know how I raced all those years before I wrote the app, well I do, it was doing a lot of math along the way… all way long. 🙂

     • Reply Harald Jul 26,2017 06:37

       By the way do you also adjust the pace reading according to the adjusted distance measurement? Say, if you hit the lap button after 950 meters (for a km), is the pace (average) corrected by -5%? If you do this again and again during a long run, the readjusted pace average should be quite precise, without having to calibrate a footpod or buying an expensive Stryd. Alternatively, since the app calculates the corrected distance anyway, the correction factor is a simple division. Both makes sense – for example if you run the NYCM, you change from Brooklyn which is quite open and GPS friendly, to downtown Manhattan, where GPS coverage isn’t so good and you tend to cut buildings 😉

       The screen could still display the GPS pace in one of the data fields if one so wishes.

       • Reply Peter Jul 26,2017 06:50

         all data (including pace, avg pace, eta, etc…) is recalculated on the fly based on the adjusted distance.

         • Reply Harald Jul 31,2017 09:57

           BTW any plans to integrate / display pace from footpod, like the “Foot Pod Pace” data field? Momentary pace from footpod plus distance correction by mile marker, that would be killer!

9. Reply Peter Jul 31,2017 10:58

   For direct ant connections i don’t have enough memory left but if you pair the footpod with your watch it should already use that as the source for speed.

    Hi Peter, it’s me again. I just ran a 10k race (Straßenlauf Dachau, https://connect.garmin.com/modern/activity/1911456331) and the data field helped me control my pace just fine – but.

    I had set auto lap to on, which may have confused the data field. I’ll switch it off next time. I must have missed this somewhere in the description. I used the Garmin footpod for instant pace, and the pace field was off by circa +10 sec all the time (between 3:55 and 4:10 min/km, where my overall average was 4:15). Instant pace was useless, but the “behind/ahead” field saved the race. Question: was the pace recalculation confused by auto lap? In some cases, auto lap counted a lap about 2 seconds before a km mark…

    Anyway: Great work, Peter, and I’ll donate in a minute. (y)

    • Reply Peter Aug 12,2017 18:34

      Hi harald,

      As long as the auto lapsize is equal to the lapsize set in the settings this should give no problem (on my own races I also set autolap on).
      I don’t influence the current pace, I just take over whatever value the connect iq framework passes on to me. But I’m sure you noticed that I offer other options for pace: avg pace, lap pace, smoothened pace, perhaps one of those will suit you better, the first two take the adjusted distance into account.
      Behind/Ahead field is also based on the adjusted distance, the behind/ahead field is the field I look at the most when I race and is one of the reasons I created the race pacer spinoff which I’ve named Peter’s Ahead Timer ( https://apps.garmin.com/en-US/apps/5751dbc6-40ab-425a-8ca4-e3afdd10eddf ).
      … I know it’s a poorly chosen name (I couldn’t think of something better 🙂 )

    Question: my aim is to run 150 km during a 24 hour run. Will this help me? Also my laps will be 934.8 meters. I guess that is not going to help?

    • Reply Peter Aug 31,2017 04:16

      Hi John,
      You can set the target distance to 150k (150000 meters) and target finish time to 24:00:00, then you should see at any point in the race in both ETA and ahead/behind time how you’re holding up against the schedule (of course during a long race like that you’ll have eating and hygiene breaks so you’ll need to build up a little bit of ahead time to cater for that)

      The lap size can not be a float value in Peter’s (Race) Pacer so instead of 934.8 you would have to set it to 935 meter, so that’ll give about 400 meter of difference at the end of the day, but the distance will be more correct than what GPS distance can give you. If you account this for in your target distance (set it a little bit higher) the ahead/behind time should be able to guide you to your goal.

      I would recommend to turn autolap off and to manual lap only when you start a new lap (you don’t have to do this each lap).

      Either way try the field out before race day to train with it and good luck with your race.

      Cheers,
      Peter

    Great Instructions.

    Just some questions as I did a demo “run” (sitting behind my desk).
    1) I managed to install and used 09:35 min/km (there was no field for target finish time…).
    Right?

    2) Also, I faked a run and of course as I was just sitting behind my desk I was “behind” immediately. So I cheated and pressed the lap (935 m) button a few times. But I suppose your app did not take it as it was outside any reasonable margin since I had not moved?

    3) Last question: I will test it and so far it looks good, but what about 45+ runners with poor reading sight like me? Any chance to have an app with less fields, e.g. just “behind” or “a

14. Reply John Evers Aug 31,2017 14:47

    3b) e.g. just “behind” or “ETA”. Extra beers in exchange…

    4) I know I should read the manual but I am lazy… Let’s say Garmin believes I ran 930 meters, but the lap really was 935 and I lapped manually. Does this mean the values of Garmin will be “corrected” or does you App distance then deviate from Garmin?

15. Reply John Evers Aug 31,2017 18:10

    Did another run. So some questions answered I guess:
    1) I assume so.
    2) I tested this and when I was close to a lap it would the difference, if I was far off it would not. That is according to design I assume.
    3) ?
    4) I believe not as the test showed a discrepancy as per design I assume.

16. Reply John Evers Aug 31,2017 18:17

    By the way…I have been looking for this functionality (i.e. combination of ETA, lap adjustment, behind/ahead) for years. Perfect if you run long distances that consist out of many laps.

17. Reply Peter Aug 31,2017 19:00

    Hi John

    The lap button corrects to the nearest distance so if your lap size is 935 and you only did a few meters it will always correct downwards (since you’re not over halfway yet)

    An app for people with poor reading eye sight and the same pacer functionality? I already got you covered, I’m running way behind on documentation, but I already made such app, I’ve named it “Peter’s (Hi Vis) Pacer”. This app can be found here: https://apps.garmin.com/en-US/apps/5751dbc6-40ab-425a-8ca4-e3afdd10eddf

    When you press the lap button the distance in Peter’s (Race) Pacer is corrected, but this will not affect the real gps distance you have covered. The distance reported after the fact will always be the gps distance, but during running you see the adjusted distance. (In your example the gps distance will remain 930m, while the data field will report 935m).

    Cheers,
    Peter.

    Hi!

    Today I bought an FR935 and tried to install Peter´s (Race) Pacer – unfortunately unsuccessfully.
    On the FR935 it´s software/firmware version 5.4 and Garmin Express says that it´s the newest version & everything is up to date.
    However, when trying to install the data fields/app Peter´s (Race) Pacer (version 4.1) it get this message: This app requires an update of your Forerunner 935. Please use Garmin Express to update your Forerunner 935.
    -> Garmin Express states that all is updated.

      hi Hans,
      This is a problem with Garmin Connect Mobile. Things that help to solve this issue (try them in this order):
      – shut down your fr935 (long press power button) and start it up again
      – unpair your mobile device and do the pairing again
      – if the above still didn’t help then the final option is to do a factory reset of your device (via the system menu) (this will wipe all user settings from the device so be sure to sync your activities to garmin connect first)

    Hi Peter,

    Awesome app. Few quick questions;

    1) I have a Fenix 3 HR. I prefer to use the “data field” rather than the “app”, because it gives me access to other data fields. Am I correct in assuming the only things missing compared to the “app” (because the Fenix 3 HR has low memory) is the pre-race screen, and the ability to write the historical data to the FIT file?

    2) Any plans to implement negative splits in the future? Example is “Race Pacer”. Should be relatively straight forward to implement; just apply a linear factor to the pace target based on position through total race distance.

    3) What happens if my watch gets a massive spike and is effectively 600m out (with auto lap set to 1.0km). Let’s say true total distance is 1km, but Garmin recorded total distance is 1.6km. When I press “lap” button, will your app round up to 2km? If so, is there anyway to fix this? (hopefully such a large GPS spike never occurs).

    • Reply Peter Oct 5,2017 10:00

      Hi Marty,

      Thanks!

      1/ I understand, I prefer the data field version myself too. Because the data field on CIQ1.x only has 16k memory I can not include all features there, but I’ve included the most important ones: all essential features are in there. The features not available in the CIQ1.x data field version are: pre-race screen, record ahead time to the FIT file, the ability to specify the target finish time or target speed (you have to specify the target as target pace), less data field options: no cadence, power, lap speed, lap time.

      2/ Yes, but it will be a different app.

      3/ The lap button rounds off to the nearest lap size multiple, so 1.6 would round to 2k. I’ve never experienced such a situation as you describe but if such a situation would present itself the only way to fix it would be to fix it gradually in the coming kilometers, eg wait till 2.4k and push the button and then at the 3k point marker correct the distance again.

      Cheers,
      Peter.

    I’ve just received a new 230 and am still quite unfamiliar with it.
    However, I realised to my disappointment that Garmin did not include the Virtual Trainer that I loved from my previous 620.
    Your appears to fix this.
    However, it appears the 230 lacks the initial screen (presumably due to lack of memory), however I cannot see a way of configuring the distance and desired race pace. Can you add some more detail?

      Hi Gareth,
      The distance and target pace is something you need to configure via the application settings. This tutorial explains how to do that: https://forums.garmin.com/forum/developers/connect-iq/connect-iq-showcase/115055-how-to-app-settings

      If you want to have the initial screen on the 230 you can use the “application” version (I have more memory available in that mode), the app version can be found here: https://apps.garmin.com/en-US/apps/ea97af1f-1e5d-4541-820c-9bd994080d4c

    Question: what is the difference between

    • Reply Peter Oct 10,2017 10:34

      hi Julien,

      Pace = current pace that the watch is reporting.
      Smooth Pace = averaged paced over the last x seconds

      So the smooth pace can be used to even out gps instabilities.

      Hi Dirk,

      the 235 is a connect iq 1 device, I’m quite limited in memory on those devices (only 16k) so I have to strip some functionality from these devices (such as the initial screen, removing lap pace, setting the target finish time,..) to allow the data field to actually run…

      There is a solution for all that though, you can use the “app version” of the field, downloadable here: https://apps.garmin.com/en-US/apps/ea97af1f-1e5d-4541-820c-9bd994080d4c

            It depends on the settings you have set on your watch to be either statute or metric. Speed is either in km/h or mile/h, pace is either in min/km or min/mile.

    For use of many people the timer is less important of other field.
    For example sometimes i don’t see the last lap time when the Watch show It and After some second/minute i want know it and i must search in other screen.
    The true is the original screen give us 4 configurable fields, your app 7 field so is fantastic!but only 3 are configurable, so 1 field less then original and for someone is a Little imperfection.

    • Reply Peter Nov 13,2017 13:31

      I can see the advantage of a lap time while doing interval training, but I can’t see the use of this while racing and I would like to keep this field race-focused. I will likely release a more general field with the same layout though, so that may be more suitable for your use case.

    Hi Peter, great app!

    is it possible to have the pace value in the top center a little bigger?
    It would be great to have the first line with just two fields, with peace and “behind” fileds more visible.

      Thanks Fabio.

      I don’t have enough memory to import a custom font and the system fonts are as they are, I can’t increase the pixel size of those, so it’s unfortunately not possible to change this. For the same reason it’s also not possible to define alternative layouts (takes memory too, which is simply not available)

      Have you looked at Peter’s (Hi Vis) Pacer, in this app you can show 2 (or 3) fields, the top field can be a field carousel. Store link is here: https://apps.garmin.com/en-US/apps/5751dbc6-40ab-425a-8ca4-e3afdd10eddf

      Correct, you can leave auto lap on. Just make sure the lap size in the app settings of Peter’s (Race) Pacer matches the auto lap size on your watch. (if you autolap by 1k set 1000 meter in app settings, if autolapping every mile set 1609 meter in app settings).

      Manual lap will apply distance correction.

    Hi Peter,
    Great data field. Tested it out last weekend. Is the “Ahead” and “behind” time by pace or total estimated time?

    • Reply Peter Mar 19,2018 02:55

      Thanks Emily 🙂
      Ahead/Behind time is the total deviation compared to the expected target time when you run at the expected pace. Eg when your target is to run 10k in 1 hour (6min/km; 10k/h) and you are currently at the 5k point in 29:55 then you are 5 seconds ahead.

32. Reply Emily Mar 19,2018 01:42

    Also, what is the difference between “Average Pace,” “Perfect Pace” and “Pace”? I saw what “Smooth Pace”is above. The default set up has average pace and pace visible. Just curious what the benefit is if the other fields.

    Thank you

    • Reply Peter Mar 19,2018 03:01

      pace = current speed in minutes/km or minutes/mile
      average pace = average speed in minutes/km or minutes/mile
      perfect pace = minimum pace you need to maintain to reach the finish for you target time. Eg when your target is to run 10k in 1 hour and you are currently at the 5k point in 29:55 then the perfect pace will be 6:01
      (as you built up 5 seconds ahead time you can run 1 second slower each kilometer and still reach the finish within your desired finish time)

      1/ Connect your device with usb to your computer and check for error logs. There’s a potential one in the root of the device called err_log.txt and one in the folder \apps\logs\ciq_log.txt.
      2/ Can you remove the Peter’s (Race) Pacer data field and then push the lap button. What happens now?
      3/ Can you uninstall Peter’s (Race) Pacer, re-download Peter’s (Race) Pacer, assign it back to the run activity profile and push the lap button. What happens now?

    My garmin 235 pauses the run when I have my stops during a run. Will the race pacer keep this into account and use the total time including the time I paused, or will it affect the perfect pace indication and the time ahead/behind?

    • Reply Peter Apr 2,2018 13:04

      It might work together with the autopause option, but I’m not sure. This data field is really meant for races, where having the autopause option set is not very relevant (the race clock does not pause when you stop). I would recommend copying the Run Activity profile to a Race activity profile where you disable the autopause option.

    Doing the configuration in Garmin Express, the dropdown menu under Target Type is only showing Target Pace, nothing else (and I would like to use Target Time).

      The forerunner 235 has only 16kb available in data field mode which is not sufficient to enable all functionality, so I had to strip a few things out in that mode… You can run the field in application mode though to have all functionality of the data field + more: https://apps.garmin.com/en-US/apps/ea97af1f-1e5d-4541-820c-9bd994080d4c

      set the following in the settings of the app:
      – target distance: custom
      – custom distance: 90000
      – target type: target finish time
      – target pace: 10:00:00
      – lap size: set this the same size as your autolap size on your watch (1000 if 1k autolap, 1609 if 1mile autolap)

      I’d suggest you train with the app before taking it to the race.

    Hi Peter,

    How do I update the Target Pace and Distance on the watch? I have the 735xt and want to be able to make those changes from the watch if possible, as I will be running varying distances throughout any given week. Is the only way to do it through Garmin Express?

      On Watch configuration is not possible for data fields.
      Next to Garmin Express you can also change the settings via Garmin Connect Mobile on your phone (but you need to be connected to the internet, a Garmin restriction…), see the how to app settings here: https://forums.garmin.com/forum/developers/connect-iq/connect-iq-showcase/115055-how-to-app-settings
