Garmin Coach - Plan for 10k - disappointment and confusion

Are you really sure that you can run this pace  or was the time goal to optimistic ?

I dis a greg Plan last Year for am HM. It was pretty hard but in the end I reached my goal

That's the point. What is the sense of showing me for 11 weeks they are confident i Will acheve the goal, if I can se myself this is hardly possible to run with this pace. They should have know this, from my training results. 

A big problem is the mostly bad pace GPS delivers to the algorithms. But I understand and agree with you that the statistics of your runs should give a better estimation for your possible performance

You are still in green position so don’t worry and enjoy your race. You’ll achieve your goal, I’m pretty sure. I experienced the same with an HM training plan. Let us know. 

@afelini thanks for your support. Maybe it is just de-motivation resulted from overload. Not sure, but I'm going to try the race anyway. everything what could be done, has been done. I'll take more sleep, more water per day and will try to relax.

I had the exact same experience with the 10K plan. Followed the plan without exceptions, stayed at the top of meter for all weeks, but I was nowhere near able to run at the desired pace. I loved the plan though, as it brought a lot of variation to my training, compared to just running the same route in the same pace three times a week. But as an instrument for training towards a specific goal, I was not a success for me either.

I have no experience with Garmin’s training plans, but you don’t seem that far off.

You can do the distance, and you can stick with the pace for a good little while - you’re doing all of that in an exhausted-from-training state.

I have a feeling that, with a good taper & pre-rwce prep, fresh at the starting line, the adrenaline & excitement of the race, and giving it all you’ve got, you might not be too far removed from your goal!

Are you in the northern hemisphere? I wonder that because as it warms up, performance will drop in the heat/humidity.

I have been following Greg's Programme for 16 weeks training for the half marathon. From about week 5 I was sitting at the highest end of the confidence meter. Now, literally 3 days out from the event, my rating has suddenly dropped back to just below the purple, into the green. I have always thought the goal was slightly ambitious, but potentially achievable. I just wonder why it has suddenly dropped now, when my training has not changed? Has anyone else experienced this?

This is a huge part of it, GPS pace fluctuations.  When I was doing the Garmin coach training plans and relying on instant pace to keep in the correct pace bracket for my runs the vibration alert would be going off for too fast one minute, too slow the next despite maintaining the same target pace.

During many runs in areas of poor GPS, my Garmin would basically turn into a random number generator when I looked at pace, where as my old Ambit 3 Peak was solid as a rock and reliable on the other wrist.  It is very demotivating when you are running to please a watch that cannot give an accurate pace. The results afterwards had huge pace dropouts and fluctuations that would always result in a much poorer average pace than on my Ambit.

Sadly Garmin don't seem to have accurate enough metrics to really make use of these training plans properly. Unless you have a footpod than is more reliable and you don't run trails.  I'm surprised more people don't realise this and complain.
