What matters for an intermediate half marathon
Add pace inside long runs carefully
Race-pace blocks are useful once the distance is stable. They should not turn every Saturday into a race.
Keep a medium-long run
One midweek endurance run can do more than another short workout when the goal is 13.1 miles.
Fuel the harder sessions
If you want strong pace work late in the block, practice calories and fluids before those sessions get long.

Which level should you choose?
Beginner
Use this if the goal is to finish well and build the long run without rushing the jump in distance.
Intermediate
Use this if you already run 10K comfortably and want tempo work plus longer aerobic runs.
Advanced
Use this if you can handle longer midweek runs and race-pace work inside long runs.
How long should the plan be?
8 weeks
A short block for runners who already have a strong long-run base.
10-12 weeks
The safest fit for many runners moving from regular 10K training into half marathon work.
14-16 weeks
Better for first-time half marathoners or anyone building weekly volume carefully.
Common mistakes to avoid
- Making every long run a race simulation
- Undertraining fuel and pacing before race day
- Choosing aggressive mileage without an endurance base
