Do the math
One plan, or all of them
This plan costs $29.95 one-time on TrainingPeaks, and it trains you for one race. Team 80/20 Gold is $16.58/month when paid annually for every plan we make — plus TrainingPeaks Premium and Mind of Matt coaching. Race more than once a year and the membership isn’t a splurge; it’s the cheaper way to train.
Questions
Plan FAQ
How long is the High School Cross Country plan?
The High School Cross Country plan is 12 weeks long. It comes in 4 levels, Level 0 through Level 3, so choose the volume tier you can sustain. Pricing starts at $29.95 on TrainingPeaks, or it's included with Team 80/20.
What does 80/20 running mean?
Roughly 80 percent of your weekly running time at low intensity and about 20 percent at moderate to high intensity. It's the intensity balance observed in elite endurance athletes across sports, and it works because easy running builds aerobic fitness while leaving you fresh enough to make the hard 20 percent genuinely hard.
Which level should I choose?
Levels are volume tiers. Level 0 is for first-timers or low-mileage runners, Level 1 for runners training moderately, Level 2 for experienced runners with solid weekly mileage, and Level 3 for high-volume competitive runners. When in doubt, choose the level matching what you've sustained recently — not what you aspire to.
Should I train by heart rate, pace, or power?
Whichever you can measure reliably and will actually follow. Heart rate is the most accessible; pace works well on flat, measured routes; running power responds instantly on hills where pace misleads. The plan structure is identical across versions — only the intensity targets differ.
How is the plan delivered?
Through TrainingPeaks. After purchase you apply the plan to your TrainingPeaks calendar, and every workout appears with its structure and intensity targets. Workouts sync to most watches and head units, and your completed sessions are scored against the plan automatically.
Is this plan included in a Team 80/20 membership?
Yes. Team 80/20 is $16.58/month when paid annually and includes every 80/20 training plan, TrainingPeaks Premium, and Mind of Matt coaching. If you expect to use more than one plan, the membership costs less than buying plans individually.
Athletes on the method
What 80/20 runners say
“I tell everyone about your plans. I’ve recently PR’d my 5k, half, full marathon, and 70.3.”

A.J. Moser
Marathon
“Thank you 80/20 Endurance! I followed the plan and ran a half marathon as a "feeler." I ran a 1:26, won my age group and was amazed that I could run that pace. Using 80/20, I went back to a marathon course where I ran a 3:23 on and ended up running a 3:13! I'm now qualified for the Boston Marathon!”

Andy Jones
Marathon
“The almost-daily runs and training consistently with the established intensity were key. I had no injuries while training!”
