OK, so this isn't really a Fenix 6 question, but just looking for tips from fellow F6 runners...
At 48, I've cycled most of my life - not in any way professional, just a hobby, on and off over the years, mostly road cycling currently and not a super-star, prefer slow and long having come from touring. I do mostly 30-60 miles on weekend runs., trying to enjoy myself as much as possible while still getting fit and improving.
Am new to running as of this year - encouraged by my wife (who's a decent runner) I finally managed to do enough to get through the 'hating it' phase that I've never previously moved beyond before abandoning. After a month or so have finally found at least what I think is a groove, feeling relaxed, and starting to sense progress. Dare I say even enjoying it, and the challenge! Took a while for me to even get used to breathing, landing feet gently, and just relaxing - stuff you can't properly learn from reading on-line etc.
So, having gone to 5K and then 10K just from doing it, I signed up for a Garmin coach half marathon plan.
One thing I'm really stuck on is slow running (in relative terms). At a pace of around 6:10/km or 6:20/km I feel like I could just keep going and I'm in Z1/Z2 depending on terrain.
Thing is, lots of the training like slow easy runs is asking me to run at nearer 6:45 or 7:15, even though I've used 5:58 as a target pace now (whereas previously I'd gone for 6:20, and will edit the plan to make it slower towards the end. I just want the watch t stop beeping at me to go slower!). Seems to make sense as it should be easier, but I really struggle to run at this pace, I feel like I'm shuffling and wobbling, and after a 90min (13km) run - my longest yet, I felt fatigued more than when I did a faster 10km, even at the 10km point. Afterwards my hips, and knees were a little sore too.
I have knee issues anyway, so I want to be careful.
Any thoughts/tips? Should I just ignore the slower speed and run at a more comfortable pace? Or am I just doing something wrong?
I don't want to end up doing loads of really slow miles, when I could probably go a little further and feel more comfortable for the same duration, unless there are serious benefits to going that slow - which I'm guessing is what's being said as that's how the plan is designed.
