Free 16-Week Training Plan for Javelina Jundred 100M
Fast desert loops, all-day heat management, and a race village every lap.
At 160.9 km with 1,919 m of elevation gain, this is an ultra-distance effort that demands careful fueling, pacing, and mental resilience. At 12 m of vertical per kilometer, much of the course is runnable — the plan focuses on building your aerobic cruising speed while preparing you for the steeper sections. The official cutoff is 30 hours, so pace management starts from week one.

Terrain autopilot
Find a matching route near you
We'll look for a loop near you that matches your next run (40 min · ~6.3 km)
and rehearses the 12 m/km demand of 100M.
Terrain intel
Mostly runnable Sonoran Desert single-track with hard-packed granite, rock, sand, and repeated rolling climbs on the Pemberton, Shallmo, Cinch, and Escondido trails.
Weather & kit
Late October can still be hot and exposed by day, then cool rapidly after sunset. Shade is limited and most 100-mile runners continue well into the night.
What this plan focuses on
Heat acclimation and disciplined hydration for exposed desert running.
Runnable ultra endurance without overpacing the early loops.
Foot care for repeated hard-packed, rocky, and sandy terrain.
Night running while maintaining a steady run-walk rhythm.
Efficient crew stops at the start-finish race village each loop.
Unified race plan · beta
Uses the same load, recovery and taper rules as race discovery, with course-specific climbing only because this course has verified elevation.
Use it for race-effort sessions and race day. Easy runs stay easy whatever the goal; the plan's efforts come from how you run now.
Your starting point
Not stated. The plan assumes a typical starting week for this race and opens at 7h 50m of running.
Fit the plan to your recent training
This schedule opens at 7h 50m of running in week one and peaks at 8h 05m in a week; the longest planned outing is 3h 15m. These are prescriptions, not proof of readiness.

Effort: Moderate: controlled reps, stop 1–2 short of failure
No-gym Session A: Bulgarian split squat, single-leg RDL, step-ups (bench/stairs), calf raises, side plank. Quality reps; stop well before failure. If 10 reps feels easy, add weight (backpack/water) so the last 2 reps feel challenging. In peak weeks, keep it short and easy.

Build relaxed time on feet at conversational effort. Practise eating and drinking on longer easy runs; easy pace is not a reason to skip fueling. For runs lasting 1 to 2.5 hours, 30 to 60 g of carbohydrate per hour is a useful starting range; beyond 2.5 hours, build toward 60 to 90 g per hour if you have practised it and tolerate it.

Practise your race-day carbohydrate plan on this long run: 30 to 90 g per hour according to expected marathon duration, pace and stomach tolerance. Build toward the higher end only if you have practised it. Count the carbohydrate grams in your gels, drinks and other food rather than following a fixed gel interval.

About the Javelina Jundred 100M course
At 160.9 km with 1,919 m of elevation gain, this is an ultra-distance effort that demands careful fueling, pacing, and mental resilience. At 12 m of vertical per kilometer, much of the course is runnable — the plan focuses on building your aerobic cruising speed while preparing you for the steeper sections. The official cutoff is 30 hours, so pace management starts from week one.
This training plan adapts the 16-week structure specifically for 160.9 km with 1,919 m of elevation gain,
scaling weekly volume and vert targets so your body is ready for race-day demands.
Ultra-distance trail races require a different approach to training than road marathons. Time on feet matters more than pace, and vertical accumulation is as important as distance.
This schedule keeps the longer outings on single days at the selected running frequency and starting load. It also includes regular easier weeks.
Training phases for 100M
The current 16-week schedule has these phases for 160.9 km and 1,919 m of climbing:
Weeks 1–6 — Base Building: Establish consistent aerobic training and introduce course-like terrain gradually.
Weeks 7–10 — Build: Reduce training load while retaining a small amount of familiar intensity.
Weeks 11–13 — Peak Volume: Practise the longest planned outings and race equipment without adding extra sessions.
Weeks 14–15 — Taper: Reduce training load while retaining a small amount of familiar intensity.
Week 16 — Race week: Reduce training and follow the race-day plan.
Pacing a runnable course
At 12 m of vertical per kilometer, much of the Javelina Jundred 100M course is runnable.
Training should emphasise aerobic cruising speed — tempo runs on rolling terrain, sustained effort on moderate climbs, and efficient flat-to-uphill transitions.
The biggest risk on a runnable course is starting too fast; practice negative-split long runs to build discipline.
