Hi! I’m currently on a half marathon training plan with my garmin watch so can’t find it online to share as I’m assuming they want you to buy the watch!
I’m currently on week 14 of 15 so my half marathon is due for the 10th which I’ll just give a go.
It goes something like this every week:
Tuesday - sprints (warm up jog for 15 mins, 10 x sprint for 20s, rest for 45s, cool down jog for 15) - this never changes
Thursday - progression run (this is done by time and has gradually increased over the course but is no longer than an hour which is 10km for me)
Saturday - the long run. (This stayed steady at about an hour for the first few weeks then every week it increased up by 5/10 mins until the max time was an 1hr 40 which got me to about 16/17km.
And that’s it, 3 runs a week and it’s worked! I’m able to run 17km without a problem if I pace myself correctly and last time I did the long one I was like “hmm could easily do 5km more now”. I am now tapering down so just a couple of light runs and a few more sprint sessions.
One thing that has massively changed it for me which I wasn’t doing before was a 5 min warm up and 5 min cool down. I used to think it was bullshit and warm up as I go but I’ve found dedicating that 5 mins to warm up has changed how my runs have actually gone. I also much prefer to work in time rather than distances as I feel it seems more achievable to me. I’m quite lucky that my watch guides me to do that on every run.
Good luck! It’s fun when you get into it!
