Slide background



The half marathon is a serious distance in its own right. Though, it can serve as a springboard for faster marathon performances.


HM marathon race intensity

  • 50% of your maximal speed
  • 85% of your VO2max
  • 3.5mmol/L blood lactate (LT = 4mmol/L)

HM energy supply

  • 98% aerobic
  • 2% anaerobic

HM muscle fiber recruitment

  • 100% of your slow-twitch fibers
  • 52% of your intermediate fast-twitch fibers
  • 2% of your super fast-twitch fibers


Half marathon training requires a unique combination of maximal aerobic capacity (VO2max), lactate threshold/tolerance, maximal running speed, resistance to fatigue, and running economy. In order to maximize these variables, you will need to carry out your training in different training zones.


What’s more, peak performance training requires a logical sequence where one adaptation piggybacks on another. I’m an advocate of non-linear periodization (multi-pace training) where the emphasis transitions from general to half marathon-specific pace.


Focus Block 1 = Twin-Base

Highly polarized training with a focus on the extreme ends of the pace spectrum.

>>> General Endurance + Maximal Speed


Focus Block 2 = Conditioning

The inclusion of middle-paces that develop your fitness to maximal levels.

>>> Lactate Threshold + VO2max


Focus Block 3 = Race-Specific

Emphasis on HM-specific training while all other variables are maintained.

>>> HM Race-Specific Endurance + Economy

HM Training Plans

Faster times from the 5K to the marathon are not just the result of training more or harder. Start training with the non-linear periodization method used by professional athletes and elite coaches.

You can choose half marathon training plans from 4 levels or have one custom made for you.

Elevate your aerobic capacity (VO2max)
Boost your lactate threshold/tolerance
Increase your neuromuscular power
Upgrade your fatigue resistance
Improve your running economy

HM Beginner

12-week plan
3 running days/week
20 miles/week (32 km/week)

HM Intermediate

12-week plan
3 - 5 running days/week
30 miles/week (48 km/week)

HM Advanced

12-week plan
4 - 6 running days/week
45 miles/week (72 km/week)

HM Pre-Elite

12-week plan
5 - 7 running days/week
