I started the season with a marathon time goal of 3:30, my 80/20 plan resulted in a time of 2:59!

Katie Walding

After switching to 80/20, I lowered my 5K time from 27:21 to 24:54, my 10K time from 57:27 to 55:06, my 10-mile time from 1:35:40 to 1:30:17, and my half-marathon time from 2:09:23 to 1:57:29. I never thought I’d be a sub-two-hour half marathoner!

The 80/20 method transformed me from a 3:13 marathoner to a 2:56 marathoner and a Boston qualifier.

80/20 is the best training plan I’ve ever done. It got me to my first PR  in three years  without beating me up and leaving me exhausted during the training. I love the variety of the workouts.

Mark Conway

Slowing down to get faster simply works. I am living it!

Jeremy Biggelaar

With an 80/20 plan I took 30 minutes off my 70.3 personal best time with a 4:56, while balancing a large family and professional commitments. I’m excited and confident to set a new PB in my next race.

Yeah. We have 80/20 gear.


80/20 training plans get results. Multiple studies reveal runners, triathletes, and other endurance athletes improve the most when they consistently do 80 percent of their training at low intensity and the other 20 percent at moderate to high intensity. Virtually all professional endurance athletes obey this “80/20 Rule,” yet the typical recreational endurance athlete spends only 50-70 percent of his or her total training time at low intensity. This so-called “moderate-intensity rut” is by far the most common and costly training mistake that endurance athletes make. The solution? An 80/20 training plan that ensures the optimal intensity balance.
