Impressions of Coach Greg 10K training plan

I just completed the Coach Greg McMillan 10K run training plan with a race on Sunday. Bottom line is it worked, and I beat my 47:00 target. If you have a race coming up and aren't working with a real coach, then it's worth a try. I particularly liked the confidence chart which updated after each workout to show if I was on track to meet my race goal. That was nice compared to other run training programs I had followed before which didn't give specific guidance on race pacing.

If Garmin is reading this there are a few issues or opportunities for improvement.

  • All of the workouts are structured by pace. This is fine if you're racing and training on flat courses but doesn't really work for hills. It would be nice if there was an option to switch the workout targets to heart rate (like with the daily suggested workout feature) or maybe running power in the future.
  • Even the "Easy Run" workouts didn't feel easy to me. They usually felt like 4/10 on the Perceived Effort scale and my heart rate was mostly in Z3. I'm not sure whether that was intentional or some kind of calibration issue. The Load Focus screen on my watch constantly showed a "Low Aerobic Shortage". There were no Z1 active recovery workouts at all.
  • Even though I had set the Perceived Effort on my watch after every workout, Garmin Connect still prompted me to select a separate difficulty level field on each one just for Garmin Coach. Why do I have to enter essentially the same data twice? Garmin Coach should be able to adapt plans based on the Perceived Effort field.
  • The training plan was supposedly "adaptive". Perhaps so, but there was no indication of what it was adapting. I would have liked some explanation of how it programmed each future workout based on the results of previous workouts.
  • After every workout, Garmin Coach gave me a Performance Rating of either "Good Job" or "Room to Grow" on the activity. What the heck does that even mean? I sometimes got "Room to Grow" even though I had hit the pace targets for all of the intervals. I would have appreciated some guidance on how to "grow".
  • Why doesn't Garmin Connect automatically set the activity Event Type field? If I did a workout as part of a training plan, then obviously the Event Type should be "Training".
  • I had to skip some of the workouts due to shin splints in my left leg. Probably because I hadn't been running as much prior to starting the plan and I should have ramped up the volume more gradually. It would be nice if the plan had an option to do some of the aerobic base building workouts as low-impact cross training on an elliptical machine or something.

Now today my watch Race Predictor screen still shows a 10k time of 51:20. Thinking But I guess that's a separate issue...

  • Hmm my experience was somewhat different, I completed the course with a target of 60min. I completed every run, and got Good Job on them all. The Confidence dial was in the top purple zone. All good you would think, but at the end of it there was no way I could do 10k in an hour. My 5k improved from 30min to 27:50, but no way I could sustain that pace for another 5k. My best 10k time is still down at 68mins.  

    It was definitely worth doing, just for the faster park-runs, but it did seem overly optimistic.  

    I’m now doing the 5k training plan with coach Amy. I’m finding it much harder to hit the targets.

  • Ii did coach Greg to improve 5k time and stuck to it (plus some strength). Felt all the way along I wasn’t progressing and training less.  At the end of 11 weeks confidence level on the app was sky high but I knew I was miles off my 5k target.  Did the race (park run) and got exactly the same time as 14 weeks prior.  Didn’t work for me.  Completely agree on hills, it was a constant challenge.

  • My girlfriend never used to run. She wanted to start. She did an internet-based course "from 0 to 5km". She was so enthusiastic about it that she started training for a half marathon afterwards. She decided to train with Jeff's Coach Plan. It worked wonderfully for her. She recommends the plan with Jeff.

  • Great post! Hope Garmin reads it and reply.

    I tried to do coach Amy Half marathon plan, but had to pause after like 3 training days because my training status was in red zone Overreaching after every single workout (even the benchmark) and easy runs based on the pace were not that easy for me as well (after one easy run my watch adjusted max heart rate up to 189, before it was 185 if I recall correctly). Would be great to have the coach plan somehow integrated into the whole system together with training status and recovery needs. Would love to have an option to choose between pace and heart rate (Is there realy this option for daily suggestion workouts?)

    If you really mean DSW, then yes, there is. See the option Target Type at fēnix 6 Series Owners Manual - Following a Daily Suggested Workout (garmin.com)

    Are you sure that you have entered the correct details for the setup?

    Did you answer the questions correctly when setting up the plan? (What distance have you run so far, what pace?, Have you entered a target time? If so, is it really realistic for you?).

    Easy Runs are more likely to be in zone 2.

    Have you already completed a training plan with a shorter distance before?

  • Would an adaptive training plan be something for you?

  • Thank you for the information!

    It's true that I'm not that experienced runner, and I haven't run the half yet. Now I'm realising that during the set up I might have been too much optimistic setting up the target:) although I've answered all the questions correctly and it did showed a message that my target wouldn't be easy for me, but still I wanted to try.

    Now I'll change the plan for a shorter distance first and will learn more about adaptive training

    Thanks again

  • You are welcome.

    That is certainly a good decision! It is better to work slowly towards your goals. It will get you to your goals better and faster in the long term.
    If you follow the rule that a large part of your training takes place in a low heart rate range, you give your body the opportunity to adapt and achieve greater endurance. There are many articles (e.g. on YouTube). Search for "run slow to run fast".

    Sometimes it can be boring to run slowly, but this in a good mix with occasional big efforts is a good strategy.

    In the beginning, the thought "why slow down when I could do it faster?" comes up from time to time.


    But most beginners who quickly lose the fun of running are those who constantly push themselves too hard, are always at their physical limit and don't make much progress as a result.

    And the basic rule of running: you don't have to prove anything to anyone.

    And the second rule of running: a training plan is a plan. It is the ideal case. Very few runners are able to follow a plan 100% consistently. There will always be days in between when the body is not able to achieve what is required in the plan. That's just the way it is. Then you postpone your training to another day, or run a little slower or shorter. It's better than overstraining your body because you think you HAVE to follow the plan STRICTLY.

    Have fun!

  • Glad it worked for your girlfriend, I think there’s lots of good plans out there to get from 0 to 5k.  I was looking to improve my performance, and hoped the plan would factor in current fitness level and ability.  Missing target is one thing, but not to have improved at all was galling.  Might try Runna app.
