Who is this Plan for?

If you have finished the marathon and you’re looking for a new challenge, chances are you are thinking of an Ultramarathon. Ultrarunning event duration in many cases exceeds Ironman® events, so they are challenging and require dedication and time to prepare.

This plan aims to help you to get your body ready for a challenging event - a 50-mile Ultramarathon in 24 weeks. It is recommended that you were exercising regularly before starting this plan, even if the plan includes 1 week intro period and starts with almost 4 hours of training the first week.

Plan Highlights

The plan includes a variety of workouts (ladders, tempo, steady-state, endurance, to name a few) arranged in four-week cycles, which will allow your body to adapt and prepare for a challenging race.

The plan is based on a percentage of your calculated Threshold Pace, however, workout descriptions also refer to RPE 1-10 (Rating of Perceived Exertion) scale. RPE will help you evaluate your 'pace by feel', so the actual distance covered may be different from one set in the workout. Target distances in some workouts are just for reference and only race day will show how your training was.

The plan does have Strength & Conditioning workouts, however for the best results they should be followed with the supervision of the gym coach.

The plan is compatible with Garmin devices so you will have structured workouts delivered straight to your watch when using the AutoSync feature after connecting your TrainingPeaks and Garmin Connect accounts. However, please check your device compatibility in the Garmin/TrainingPeaks website.

Sample Day 4


For this time trial test, be rested and perform it on a running track, or on any other flat, smooth course. Warm up for 5 minutes by gradually accelerating to a tempo which you believe you can sustain for 30 continuous minutes, but not longer. Do not start too fast, stay consistent and have in mind that test is divided into 10-minute and 20-minute parts. They are for calculation purposes only, so do not drop your pace after 10-minute lap is complete; you have to run for continuous 30 minutes at the fastest pace you can sustain for that amount of time. After completing the test, cool down for 5 minutes.

Your average 30 min. pace will be your Lactate Threshold Pace (LTP). Your average HR for the last 20 min. of the test will be your Lactate Threshold Heart Rate (LTHR).
