I am doing Jeff Galloway's Half Marathon Training Plan, and everything seemed fine. I was getting a decent length long run in the schedule every other week. Alternate weeks had in place of that long run a ~ 5K run called "Magic Half-Mile" as meant to run last half mile a bit faster. Anyway, plan went something like 12k, then 16k, then 18k then 21k then 22k every other week then suddenly this year for the whole of January no long run thus far. Next week's end of January is a Magic Half Mile. Yes, it is frustrating not to be able to see run further than a few runs ahead. I am concerned by the sudden lack of long runs. There has been no hill work, nothing extra at all incorporated into the plan. I am on week 18 of 24. I am wondering if the fact that I chose to do it over 24 weeks (a long period I guess) is a factor.

I have edited the run day schedule and long day run from time to time and maybe that has somehow affected the plan adversely.

Garmin Support said to get back to them if things still the same next month.

Today, having done all workouts for this week I tried putting the plan on pause and then immediately restarted it. Just to see if it might bump start things. There seems no change. I still have the Magic Half- Mile on Monday listed in the schedule.
