Below is a 12 week half-marathon plan that I put together for a woman that I coached. She was an 18:20 5k runner and went on to run 17:35 on the roads during this training cycle.
Because she was a lower volume runner due to some back issues (45 miles per week was her high mileage mark, plus one day of aerobic cross training), and because her goal race came in the middle of our local race series which emphasized 5k to 10k distances and breaking 18:00 in the 5k was also a goal in this cycle, we used a 5k/10k approach, adjusting the tempo workouts and then "racing up." Below are the quality days for those 12 weeks, starting 12 weeks out from race day.
A few things worth noting:
- Note the conscious effort to grow into the longer cruise interval sessions, starting with 4 x 2000m cruise intervals and eventually working up to 3 x 3200m intervals.
- Note that some of the tempo sessions were integrated into her long run.
- Note that one of the quality sessions per week starting in week 10 really focused more on race modeling and fitness maintenance than on building additional fitness.
-Note that there is not a lot of rep work during this cycle. She had done a bit of this earlier in the year before this cycle started, and I only had 12 weeks to get ready, so we had to prioritize what would be most important for her goal races.
- Note that, despite this being a 5k centric plan, there was not a vo2max workout on the calendar "week in, week out." She had 6 meaningful v02max workouts (including her Turkey Trot) spread out over about 8 weeks.
- Note that we did not include any hill work. That was not because Daniels doesn't like hill work, but rather because (1) we live in a pancake flat area, and (2) hill work serves the same purpose as rep work in a Daniels scheme, and, as noted above, we had to prioritize vo2max and threshold workouts because of the time available to us (and because she had already recently done some rep work).
- What you don't see is that the weeks where you have the highest intensity also tended to be the weeks with the lowest mileage and vice versa.

Half Marathon (I cannot recall the time, but she had a slow race - she either peaked a week too early or she had an emotional let down after the :30 5k PR the week before)
If I were emphasizing an October marathon (as I did in 2015 and 2018), I would emphasize recovery from my prior cycle, then easy distance, then volume building up through the beginning of June, then I would build in a 6 week block of doing one 5k paced workout and one tempo workout per week from June through mid-July, with a 12 week block emphasizing tempo work (with some limited number of marathon paced workouts mixed in) to close things out for the marathon cycle.
I would probably go with a 5k oriented half marathon approach employing principles similar to the plan above in the period from now through March as I think it would (1) allow you to get used to some of the longer cruise interval style workouts that you will do in marathon training, and (2) get you comfortable working at vo2max pace in advance of the block of work that you will be doing from June through mid-July.
