100 Mile Ultra Running Training Plan


  • 17 weeks, 7 days/week, including 3 “taper” weeks
  • Designed to be completed 17 weeks directly before your race
  • Not suited for beginners (you should be comfortable with 30 miles of volume/week to start)
  • This training plan is one of the 450+ Plans included with an Athlete’s Subscription.


This 17-Week, 17 day/week training program is sport-specifically designed to prepare fit athletes to run a 100-Mile Ultra Marathon. This training plan is specifically designed to be completed the 17 weeks directly before your race.

This training program has 4 general objectives:

  1. Increase speed over ground
  2. Increase running-specific leg strength, core strength and upper body strength
  3. Increase running aerobic base and efficiency for longer distance runs
  4. Prepare your mental fitness, leg strength endurance and cardio fitness for a 100-mile event

This is Version 2 of this plan, updated June 2021.16



Speed Over Ground Work
This training program deploys multiple 6, 9, and 12 mile assessments and uses the athlete’s assessment time to dictate paces for follow-on, shorter, threshold intervals to develop speed over ground. It’s intended that the assessments and follow-on intervals be completed on a flat course – a running track or similar.

Easy and Moderate Paced Runs
While the Speed Over Groundwork in the plan is anchored in 4-5 week blocks, the plan’s easy and moderate pace, longer run volume, increases throughout the plan.

You’ll run easy, long-distance two times/week, and moderate-paced, long-distance one time per week. Your moderate-pace run will occur on Saturday, and will be the longest run of the training week (starts at 8 miles, and increased to 40 miles).

Total weekly running volume in the plan begins at 30 Miles total in Week 1 and increased to 90 Miles total in week 14.

Weeks, 15, 16, and 17 are “taper” weeks into your race at the end of week 17.

1)  Mission Direct

Gym numbers mean nothing. All that matters is mission performance. 

To this end, MTI’s fitness solutions and programming are not boxed in by convention, tradition, orthodoxy, public opinion or any other artificial constraint driven by inside or outside forces.

We begin with the raw fitness demands of the mission and build a fitness solution which directly prepares the athlete for those demands.


2) Fitness Solutions Built from the Ground Up

MTI’s programming is not “re-tread” bodybuilding, football, CrossFit, kettlebell, strength or general fitness programming. We’ve built our fitness programming for mountain and tactical athletes from the ground up.

The Fluid Periodization methodology we deploy to concurrently train multiple fitness attributes is completely original and has continued to evolve and improve over the years.

Our mid-section training methodology, Chassis Integrity, is also original, as is our endurance programming, 7 strength training progressions, tactical agility, and work capacity programming.

Our mountain sports pre-season training plans, tactical PFT, selection, school, course, and fitness improvement training plans across military, LE and Fire Rescue are MTI-developed, tested and athlete-proven.

Over the years hundreds of athletes and coaches have taken our advanced programming and unit fitness leader programming courses and MTI is widely recognized within the mountain and tactical professions and fitness media as a thought leader in fitness programming for military and tactical athletes.


3) The MTI Method

→ Research: MTI begins program design with extensive research of the fitness demands of the mission, sport or event, identifies the exercises and progressions which sport-specifically meet those demands, chose end-of-cycle goals, and program backward to design the training plan.

→ Deploy & Assess: We deploy the training plan “Lab Rats” at our Wyoming facility. Training session and cycle issues are identified and fixed as we work through the training plan. Post cycle we assess the programming’s effectiveness and efficiency. We keep the stuff that works, and fix or toss the stuff that doesn’t.

→ Publish & Assess Again: Plan is published for purchase as an individual training plan and made available to our subscribers. Feedback/results are assessed.

→ Iterate: We take what we learn from lab rats and athletes, re-visit, update and improve already published training plans. Several of our individual training plans are on their 4th or 5th version.


4) Mission-Direct Research

MTI exists to “Improve Mountain and Tactical Athletes mission performance and keep them safe.” To that end, we have developed a unique research methodology aimed at identifying real world areas of improvement and identifying immediately deployable mission-direct solutions. Click HERE to learn more about MTI’s Mission-Direct Research methodology, and Here to read about just few of our research efforts.

5) Field Proven

Our stuff works. Weekly we receive unsolicited reviews of our programming and testimonials to its effectiveness.


6) Programming Breadth

MTI’s library of 200+ sport-specific fitness plans for mountain and tactical athletes is unmatched. Resources range from specific programming for tactical special forces selections, to specific plans for climbing Rainier and Denali, to general fitness solutions such as running improvement, to post-rehab from injury.

Over the past decade, MTI has partnered with hundreds of athletes throughout their individual mountain and tactical careers, and provided fitness solutions as they face new mountain objectives, tactical schools, selections, PFTs and deployments, and came back from injury.


7) Worldwide Influence

Our work is not limited to US Athletes.

We’ve developed selection-specific training plans for Canadian, UK, Australian and German Special Forces Selections and worked with individual military personnel from Scandinavia, South, and Central America.

Canadian, Australian, UK and western European law enforcement and fire/rescue athletes have used MTI programming for mission-direct fitness.

On the mountain side, Alpinists from Japan to Slovakia have consulted with MTI and used MTI’s programming to prepare for mountain objectives.


8) Mission Performance beyond Fitness

MTI’s exists is to improve Mission Performance for mountain and tactical athletes and keep them safe. 

This focus on “mission direct” solutions, enhancements and improvements drives our work and research and extends beyond fitness solutions to include training, leadership, gear, team culture, and safety. 

Fitness is just one area of our work.

Our non-fitness research has included tactical cultures, combat uniforms, and gore-tex performance, and effect of stress on marksmanship.

Our work on defining what it means to be a Quiet Professional has had penetrating influence and driven healthy conversations with both mountain and tactical professionals.


9) Direct, Honest, Clear Answers

Since 2007 we’ve taken and answered dozens of questions weekly from mountain and tactical athletes. We’ve saved these individual Q&A’s and now thousands are archived on our site.

We’re not salesmen, and our answers are noted for their directness, honesty, and clarity. Our stuff isn’t for everyone. If we can help, we’ll let you know. If we can’t, we’ll let you know that, too.

All of the Above is Backed Up By Our Promise: Our Stuff Works. Guaranteed.

Our Stuff Works. Guaranteed.

By Rob Shaul

I received notes frequently from athletes hesitant to purchase a subscription or training plans asking me to sell them on why they should make the purchase.

While I understand the question, I’m not a salesman – so I can’t put a hard sale on anyone for our programming.

I can tell them the process we go through to design our programming.

We begin with extensive research on the fitness demands of the event, identify the exercises and progressions which sport specifically meet those demands, chose end-of-cycle goals, and program backward to design the plan.

Then we test the cycle on ourselves and our lab rats here in Wyoming. We document, note what works and doesn’t work, re-assess, and make changes and modifications.

Then we publish the programming in the form of one of our plans or as part of our subscription daily training sessions for tactical and mountain athletes.
We don’t stop there – our daily programming is the “tip of the spear” for our programming evolution. We use these sessions to learn and make continuous improvement.

As we learn more and improve, we go back, and update the sport-specific training plans on the website. For example, we’re currently on Version 5 of our Ruck Based Selection Training Plan and Version 3 of our Dryland Ski Training Plan and Version 4 of our Big Game Back Country Hunting Training Plan.

We understand our programing isn’t cheap, but we believe it’s a great value. The $79 for the Ruck Based Selection Training Plan, and $39 for the Dryland Ski Training Plan reflect the, research, work, innovative theory, iteration, testing and feedback we’ve put in and received to make these plans effective.

All that matters for us is outside performance, and we feel strongly that Our Stuff Works in the real world.

Here’s our guarantee:

1) Individual Training Plan Purchase:
If you purchase an individual training plan, follow it as prescribed before your season/event/pft/selection, and if you don’t feel you were physically ready for your season/event/pft/selection, and/or didn’t see dramatic improvements in your early season performance, we’ll refund your money, no questions asked.

2) Athlete’s Subscription

Just wanted to give out a huge kudos to you and your 100 Mile Training Plan.  I just completed the Bryce Canyon 100 in 33:45 with the use of your training plan.  This is the fourth 100 I've completed and I've used various other plans and expensive coaches, your plan crushes them all in my opinion.

For the first time in all my training I enjoyed all the workout sessions, I could see week to week improvement in my speed, strength, and endurance.

One of the most impressive things I saw from the training plan during my race was my consistent speed across the course and the distance. This was most impressive to me because I live in Chesapeake, VA where the highest hill is an over pass and 99% of my training is done on flats, while the Bryce 100 has 18,800 vertical gain.

I also credit my quick recovery to your plan. While I had a few aches and pains following the run, with in a few days I was back to a relatively normal range of motion. I also never really felt "beat up" like I have during past 100's and I credit that to the strength and chassis work programmed in.

Huge thanks to you and your training plan for helping make my run a success. This will be my go to plan for all my ultras.

Thanks again"
