@mystygage I'm a #garmin user since mid-October, and I thought why not give the coach a try for my next marathon in March (finished six marathons with a static training plan or just following a fixed ratio of long/slow runs and various interval sessions).
Currently I'm quite annoyed with the dynamic adjustments. Usually, I look at the training plan for the next day, then select a route and time slot. In the morning, more often than not the training is changed to something completely different.
First couple of times I thought it was because of imbalance of training load. But today: everything seemed perfect (good sleep score, load was 'optimal' or even tending too low, high readiness score, perfect balance between anaerobic, high aerobic, low aerobic load) and then my long run got switched for a 30 minute recovery run. Common, you can't be serious. You don't take away someone's long run.
I can still select another day's training on the watch, so I chose next Sunday's long run. However, in my opinion these radical adjustments shouldn't be made day to day. Instead, adjustments should be scheduled a couple of days ahead of time.
I will still follow the garmin coach a bit more, but there is definitely room for improvement.
I wish there was a switch I could flip to at least fix the workout for the next day.
I would be particularly interested in the training volume for the longer runs; with the old Garmin coaches with HM plans, I sometimes found them a bit on the short side. I think it's okay to slightly go over the distance for a HM, especially since I've done a lot of HM training and wasn't training for my first HM. (2/3)
Currently I have not activated a coach, but I have set the beforemnetioned race in April as my next race. So the Daily Suggested Workouts go in this direction and the suggestion for this week - especially for Sunday - looks ok.
I will continue to watch it for a few more days and maybe hope for a report from a runner who has already entered the high volume phase with 32 or 35 kilometres for the long run. (3/3)
@mystygage I'm more and more underwhelmed with #Garmin's Coach for marathon training.
The feedback is just too contradictory. I'm in the "building" phase, but most key figures suggest a training load below the optimum (and that is my personal feeling as well). Still the coach keeps postponing demanding sessions. It just piles on more basic and recovery runs. At the same time I have too much "low aerobic" training
The total weekly distances and the longrun times - if a longrun is scheduled at all - are nowhere near what I would expect at this stage for a marathon training (and what other plans suggest).
The algorithm is way too sensitive for my bike commutes as well (at very moderate speed). I want to track these for statistics and because I use the Garmin Varia radar system coupled to my watch. But, alas, additional training, additional recovery time, more basic runs to come.
At the same time my recent performance, predictions and also 5k/10k race times align well with my current target, even quite a bit on the conservative side. So I'm pretty sure I'm not overreaching.
@mystygage On my watch I can choose a different training from the already scheduled days of the plan (when I start the activity), which helps a bit. But yes I agree, there should be a way to fine-tune the whole plan and align it to reality.
Currently I'm in the building phase and I don't get any long runs, only basis, threshold and sprints. But I have scheduled my six long runs manually following a different plan, yesterdays training was one of those. For the remaining 9 weeks, I will just mix and match whatever feels right.
I have a 10k next week which is in my Garmin events (as secondary event), maybe this is also affects the algorithm, but in any case the long runs leading to the main event should have higher priority. Maybe Garmin has a different philosophy about how Marathon training works, but I learned that 5-7 (30k+) long runs are essential. Reserve some time for tapering, another HM event and potential illness in between, then I'm still on track but should not risk to skip any more weekends.
