50 Mile Ultramarathon Training Plan
Written by Andrew Taylor. USATF Level 1 Coach. Coaching runners since 2010.
50 miles becomes a distance you have finished.
You are already crushing marathons or other ultramarathon distances, backing up heavy back-to-back weekend runs, and keeping the rest of your week intact. You intimately know what 6 or 7 hours of relentless movement demands from your body and mind. Now, it is time to extend that power across the entire day.
Stepping up to the 50 mile mark does not require you to become a completely different runner, it just requires a deeper reserve. The secret lies in holding your form, nailing your fueling, and maintaining sharp judgment when you are deep into the pain cave.
This 24-week blueprint stacks your highest-value work across the weekend to simulate that late-race fatigue, while keeping your weekday runs tightly controlled so you can recover and repeat. You have the foundation, now let’s build the endurance to back it up.
- 24 week plan
- 5 runs per week
- 30 to 72 miles a week
- Longest run 31 miles
- 120 coached runs

Is This You?
If your next race is 50K or shorter, choose the 50K plan. If you are moving beyond 50 miles, use the 100K plan.

The Weekend Works As One Long Session
This 50 mile plan treats Saturday and Sunday as one session split across 2 mornings. The pair is there in Week 1 and never leaves. You get the whole build to learn what the second morning is supposed to feel like, and how to start it well.
Fifty miles is not a long marathon. Most of the race happens after your legs stopped feeling fresh hours earlier. Even a 31-mile Saturday covers only 62% of the distance, and it cannot show you what the last 19 miles feel like. Starting again Sunday morning before recovery gives you direct practice moving in that state.
Saturday grows from 14 miles to 31, while Sunday grows from 6 to 12. By the dress rehearsal, you cover 43 miles across 2 days. Sunday becomes optional during recovery weeks and throughout the taper, giving the pattern enough room to remain repeatable across all 24 weeks. You arrive with months of practice making Sunday part of one continuous weekend effort.
Or skip the fixed plan entirely
Every plan here is written the day you buy it and does not change after that. Coaching does. Andrew writes your next 4 weeks against the training you actually did, then rewrites it 4 weeks later, and again after that. Across a 24-week build, the plan keeps adapting to your training and your schedule.

What Makes A Sunrise Running Plan Different
Most plans tell you how far to run. This one tells you how it should feel, and what to do when it doesn’t.
More on why this Sunrise Running plan runs on effort instead of pace.
A Real Week From The Plan
Week 19 puts 43 miles across two mornings and rehearses the race before the taper.
| Day | Session | Time | What It Asks For |
|---|---|---|---|
| Monday | Rest or Light Movement | Rest | Take the day off or keep any movement gentle. |
| Tuesday | Easy Run Plus Strides, Strength and Mobility for Runners | 8 miles + 20 minutes | Run easy, add relaxed strides and complete the first strength session. |
| Wednesday | Steady Effort Run, Strength and Mobility for Runners | 15 miles + 20 minutes | Hold a controlled effort, then complete strength work without loading your legs. |
| Thursday | Recovery Run | 6 miles | Keep the effort low after the longest midweek run. |
| Friday | Rest With Optional Mobility and Recovery | Rest or 20 minutes | Take the day off or complete gentle recovery work. |
| Saturday | Long Run or 50K Effort | 31 miles | Run a full rehearsal of your effort, fueling, terrain and kit. |
| Sunday | Back-to-Back Run | 12 miles | Start slowly and let your legs come around as you move. |
| Week total | 72 miles | The dress rehearsal and the largest week of the plan. |
Two days a week carry no running at all. They are there so Tuesday and Thursday are still worth doing in Week 10.
Every Week Opens With A Note Like This One
Week 15 tests your biggest ordinary weekend before the dress rehearsal arrives.
The largest ordinary week of your plan. Get everything from it that you can.
Only your dress rehearsal week carries more than this. So treat the weekend as the last big open-ended block of training. Race terrain if you can. Full kit. Real fueling. Climbs hiked properly and descents run under control.
Then run Sunday’s 12 with the single goal of holding good form throughout. Forty miles across two days is a serious ask on its own, and nothing needs adding to it.
Focus this week on:
- Race terrain, race kit and race nutrition across both days
- Efficient power hiking even when tired
- Controlled descending, because quads decide the back half of a 50
- Stopping short if anything sharp appears, with the peak block still ahead
A recovery week comes next, and Sunday becomes optional.
You receive 24 weekly notes like this, plus a separate coaching note on every run.
The 24 Weeks, Phase By Phase
| Weeks | Phase | Mileage | What It Does |
|---|---|---|---|
| 1 to 4 | Foundation | 36 to 46 miles | The back-to-back weekend is in place from week 1, with a Saturday long run and a shorter Sunday run, and mileage climbs from 38 to 46 before week 4 steps back to 36. |
| 5 to 12 | Build 1 | 42 to 65 miles | Mileage builds through 2 blocks with recovery in weeks 8 and 12, the long run reaches 25 miles, and the Sunday back-to-back run grows from 9 to 12 miles. |
| 13 to 16 | Build 2 | 54 to 69 miles | The biggest sustained block of the plan, with the long run reaching 28 miles and the medium long run 15, before week 16 reduces the workload to 54 miles for recovery. |
| 17 to 19 | Peak | 63 to 72 miles | 2 peak weeks lead into the dress rehearsal in week 19, where a 31-mile Saturday run at 50K effort is followed by 12 more miles on Sunday. It is the largest week at 72 miles. |
| 20 to 23 | Taper | 30 to 55 miles | Week 20 transitions out of the peak at 55 miles, then mileage decreases to 30 while the Sunday back-to-back run becomes optional and the long run shortens from 21 miles to 11. |
| 24 | Race Week | 14 miles + race | 3 scheduled runs lead into the race, with an optional 2-mile shakeout Friday if it helps you feel ready. Everything is easy and nothing is longer than 5 miles. |

Frequently Asked Questions
You are ready if you have finished a 50K or trained through a 50K build, you run 5 days a week, and a 14-mile long run followed by 6 miles the next morning is already something you handle. Those should already be true, not goals for later. Week 1 asks for 38 miles across 5 runs.
This plan is not the right fit if you can only run long on one weekend morning. The Sunday run carries the work the plan is built around, and skipping it repeatedly removes that structure. The 50K plan is the better alternative because its weekend pair appears only twice rather than every week.
The 50K plan teaches the fueling, hiking and terrain skills surrounding ultra running, with a genuine weekend pair appearing twice. This plan assumes those skills are familiar and puts the Saturday-Sunday pair in every week from Week 1 onward. What is new is not Saturday’s distance. It is being asked to run well again on Sunday.
The 31-mile run is a rehearsal, not a preview of the full race. The 12 miles the next morning complete the work by asking you to start moving before recovery. Adding more to Saturday would take too much from the second day and from the training week that follows.
Skip the missed run and continue with the next scheduled session. Do not stack runs, squeeze a long run into the wrong place, or turn a recovery week into a make-up week. Consistency across the 24 weeks of the plan beats being perfect for 2.
No. Every session is written on an RPE 1 to 10 effort scale. That means the plan works on hills, in heat, on tired legs and at any fitness level, and it keeps working as you get faster.
Pick your race, set your start date, and the plan builds backward from it. If the race moves, the plan moves. You keep it for life, which means the next build starts from something you already know works.
The 100K comes next once your race distance passes 50 miles. Running this plan a second time is also worth considering, because you would start the build from fitness you have already proven rather than from the bottom, and the weekend pair would already be familiar.
