Does this window fit your starting point?

Use this window when your recent training is steady and the opening week will not be a mileage jump. If you are returning after a long break, twelve weeks is too little room to rebuild and peak at the same time.

  • Your weekly mileage has been consistent for the last six to eight weeks.
  • You have completed recent long runs and do not need to rebuild from three easy miles.
  • You can protect the same number of run days from week one through race week.
  • You are prepared to begin race-specific work early instead of using a long base phase.

The 12-week REVEL Big Cottonwood Marathon calendar

These dates define the job of each phase. Your current mileage, recent longest run, experience, goal, and available days still decide the actual workouts inside them.

Settle

Weeks 1–2

Jun 20, 2027–Jul 3, 2027

Hold close to your current volume, establish the weekly rhythm, and make sure the opening load is honest.

Build

Weeks 3–7

Jul 4, 2027–Aug 7, 2027

Grow the long run and weekly work with step-back weeks intact. There is no room to repay missed mileage.

Peak

Weeks 8–10

Aug 8, 2027–Aug 28, 2027

Complete the most race-specific long runs, rehearse fueling, and practice the terrain that will decide the final 10K.

Taper

Weeks 11–12

Aug 29, 2027–Sep 11, 2027

Reduce volume, keep the routine familiar, and arrive on race day without trying to squeeze in one more big week.

Make the window specific to REVEL Big Cottonwood Marathon.

Course-specific work starts early in a 12-week build. Put the race's terrain and expected conditions into long runs once the opening weeks feel controlled, without adding extra hard days.

How to train for REVEL Big Cottonwood

Train for REVEL Big Cottonwood by building eccentric quad durability, a separate project from marathon fitness that takes roughly eight weeks. The race's own guidance is downhill work about once every 10 to 14 days, using repeats between a quarter mile and a mile, at lower total volume than a normal session.

Technique matters as much as volume. The mistake is braking: reaching the foot out ahead of the body to slow yourself, which multiplies the force through the knees and quads on every single step. Pitch forward slightly from the hips, shorten your stride, lift your cadence, and let the hill carry you. Done properly it feels like gliding, and it runs 15 to 20 seconds per mile quicker than normal for the same effort.

Then plan the second half, because only about 11 miles are run outside the canyon and those are the ones that hurt. Do at least two long runs that finish with 8 to 10 miles at goal pace immediately after a sustained descent. That exact sequence, downhill and then flat at pace, is what race day asks for, and almost nobody rehearses it.

Ramp downhill volume gradually. One overambitious session can leave you sore enough to lose a week of quality work, and quad damage doesn't respond to willpower.

Boston qualifying note. The Boston Marathon adds 10 minutes to qualifying times run on courses that drop this much, starting with 2027 registration, so a time here counts as 10 minutes slower than the clock.

Start-line temperature is not listed for this race. The course finishes thousands of feet below where it starts, so the weather recorded in the finish city does not describe the start line.

12-week REVEL Big Cottonwood Marathon plan questions, answered.

When should I start a 12-week REVEL Big Cottonwood Marathon plan?

The 2027 REVEL Big Cottonwood Marathon is scheduled for September 11, 2027, so the 12-week window opens around June 19, 2027. Treat that as the outside edge of the window, then line week one up with the plan's normal weekly rhythm.

Is a 12-week plan long enough for the REVEL Big Cottonwood Marathon?

Use this window when your recent training is steady and the opening week will not be a mileage jump. If you are returning after a long break, twelve weeks is too little room to rebuild and peak at the same time. The course does not change the opening load you can handle, so choose from your current mileage and recent longest run before adding race-specific terrain.

How should I prepare for the REVEL Big Cottonwood Marathon course in 12 weeks?

Course-specific work starts early in a 12-week build. Put the race's terrain and expected conditions into long runs once the opening weeks feel controlled, without adding extra hard days. Train for REVEL Big Cottonwood by building eccentric quad durability, a separate project from marathon fitness that takes roughly eight weeks. The race's own guidance is downhill work about once every 10 to 14 days, using repeats between a quarter mile and a mile, at lower total volume than a normal session.

What if the 12-week REVEL Big Cottonwood Marathon window has already started?

Do not double weeks or cram missed mileage into the remaining calendar. Use your current mileage, recent longest run, experience, goal, and available days to choose a plan that can enter at an appropriate point while preserving the taper.

How much elevation does REVEL Big Cottonwood drop?

About 5,244 feet net. REVEL Big Cottonwood starts near 9,625 feet on Guardsman Pass and finishes around 4,377 feet in the Salt Lake valley, with roughly 5,465 feet of total descent against only about 221 feet of climbing. Nearly 15 miles of that comes in the canyon at an average 5% grade.

Is REVEL Big Cottonwood a good Boston qualifier?

It's fast, but the rules changed. The course produced high qualifying rates historically, 21.3% of finishers in 2023 and 27.4% in 2022. From the 2027 Boston registration cycle the BAA applies a net downhill index, and this course carries a 10 minute adjustment, so a time here counts as 10 minutes slower for registration.
