This plan is built from the SUC (Sacramento Ultra Crew) training system — a gritty, no-fluff philosophy focused on building durable, race-ready ultrarunners. Every workout reflects the SUC pillars: back-to-back long runs, terrain-specific stress, fueling simulation, and fatigue-layered progression. If you’re training with SUC, this plan aligns with our weekly runs. If you’re running it solo, you’re still getting the same blueprint we use to build endurance monsters.

OVERVIEW

This 20-week training plan is built to turn you into an endurance machine. You're not just stacking miles — you're building a resilience-first racing system that thrives when everything else is falling apart. This plan focuses on Back-to-back long runs, vert and fueling specific long runs, mid-week threshold / tempo workouts and an all systems approach to 100 mile performance. Every workout has purpose. Every phase builds toward execution under stress.

PLAN EXPECTATIONS & ATHLETE FIT

This plan is built for intermediate or experienced trail ultrarunners training for a 100-mile race who already understand the basics of long-run fueling, have experience with 4–5 run days per week, and are comfortable navigating fatigue.

It is not for beginners looking to “just finish” — this plan is designed to build systems, not just check boxes. You'll train in the heat, climb and descend on tired legs, run at night, and practice every single element you’ll need on race day. We train for the worst so you can race at your best.

BEST FOR ATHLETES WHO:

Have completed at least one 50K or 50M

Can comfortably run 40 miles/week without injury

Are willing to train on trails, in vert, and during high-fatigue blocks

Want to do more than finish — want to feel trained, tested, and ready

Thrive with structure, but don’t need daily check-ins or hand-holding

COACHING & COMMUNICATION:

This plan is self-guided. There is no direct coach access unless you're working with SUC 1:1.

If you're an independent athlete who trains with intent and doesn’t need motivational fluff or sterile explanations, you’ll thrive here. Every workout has a purpose and description — you’ll know exactly what to do and why it matters.

GEAR + EQUIPMENT NEEDED:

Trail shoes with grip (multiple pairs suggested)

Running vest, handhelds, or bottles (race-day gear encouraged for long runs)

Headlamp for night simulation workouts

Trail access with climbing/descending terrain

Watch with HR or GPS (threshold HR zones used in key workouts)

Nutrition setup for long runs: carbs, electrolytes, hydration

Foam roller or mobility tools for support work
