Understanding the Speedgoat 105km Challenge
The Speedgoat 105km represents one of the most demanding ultramarathons in the world, testing every aspect of your fitness and mental fortitude. As a 105-kilometer mountain trail race with significant elevation changes, this ultra demands specialized preparation that goes far beyond standard marathon training. The technical terrain, sustained climbing, and extended time on your feet require a multifaceted approach to training that builds not just aerobic capacity, but mountain-specific strength, technical footwork, and the psychological resilience to push through fatigue when the finish line is still hours away.
This race attracts elite ultrarunners and serious amateur competitors seeking to prove themselves on one of the sport's most prestigious stages. The combination of distance, elevation gain, and technical terrain means that success depends on deliberate preparation across multiple training domains: long-distance aerobic capacity, specific elevation adaptation, technical trail skills, and comprehensive race-day nutrition planning. The Speedgoat demands respect—underprepared runners face not just a difficult day but genuine risk of DNF or serious physical breakdown on the course.

105km distance requires 12-16 weeks of structured training with progressive volume
Mountain terrain demands technical footwork practice and strength-specific sessions
Elevation gain creates substantial energy demands requiring careful pacing and fueling
Elite field necessitates strong baseline fitness before beginning specific training
Mental preparation for 10+ hours of mountain running is as critical as physical training

Speedgoat Race Day Tips
1Start conservatively on the opening sections regardless of how you feel—the race is decided in the later stages
2Practice your fueling strategy extensively in training; the race is not the time to experiment with nutrition
3Use aid stations for more than refueling: ice, mental reset, crew contact, and body checks are critical
4Manage pacing by effort rather than pace—expect significant pace variation due to elevation and terrain
5Prepare for multiple weather scenarios and terrain challenges; flexibility and adaptability often determine success
6Sleep strategy and pre-race rest matter as much as training; arrive well-rested and confident
7Break the race into manageable segments rather than thinking about the full 105km distance
8Practice descending technique extensively; many runners lose significant time and energy on downhills
9Crew communication and logistics must be pre-planned and practiced to ensure consistent support at aid stations
10Mental preparation for the dark, difficult middle miles (hours 5-8) is essential—build positive self-talk strategies

Frequently Asked Questions
How many weeks should I train for the Speedgoat 105km ultra?
A comprehensive 16-week training block provides adequate time to build the specific fitness needed for a 105km mountain ultra. This breaks into four 4-week phases: base building, strength and technical development, race-specific preparation, and peak/taper. Runners with strong trail ultramarathon backgrounds might compress to 12 weeks, while those new to ultras should extend to 18-20 weeks. The critical factor is the total volume accumulated—aim for 3000-4000 kilometers of running in the 6 months preceding your Speedgoat training block.
What elevation training is necessary for a race with this much climbing?
Specific elevation adaptation separates successful Speedgoat runners from those who struggle. Incorporate sustained vertical gain work 2-3 times weekly, including both long elevation-gain runs (1500m+ of climbing) and shorter high-intensity vertical repeats. If living at or near elevation (1500m+), you gain natural adaptation. Runners at sea level should plan 2-3 weeks of altitude training or frequent trips to mountain terrain. Simulate race-day elevation challenges during back-to-back long run weekends where Saturday involves 1000+ meters of climbing and Sunday's 20-25km continues similar terrain.
How should nutrition strategy differ for a 105km mountain ultra versus road marathons?
Speedgoat's duration (10-15+ hours) and elevation demand a completely different fueling approach than marathons. You must plan for 250-300 calories per hour of sustained effort, with emphasis on easily-digestible sources: gels, sports drinks, and real food (pretzels, sandwiches, fruit) become viable as intensity drops. Test multiple nutrition products extensively in training to identify what your gut tolerates during prolonged effort and fatigue. Account for altitude affecting digestion and appetite suppression. Practice eating and drinking immediately when fresh at the start; appetite decreases significantly during the race, so establish consumption habits early.
Should I train at altitude for Speedgoat preparation?
Altitude training provides significant advantages if the race course includes high elevation sections. If you live at sea level, aim for 2-3 weeks at 1500-2500m elevation 6-8 weeks before the race for maximum acclimatization benefit. Alternatively, conduct multiple weekend trips to mountain terrain at altitude during your training block. If altitude training is unavailable, focus on accumulated vertical gain in your local terrain and extended time at race pace in challenging conditions. For precise information about Speedgoat's elevation profile and maximum altitude, check https://speedgoat.utmb.world to determine if altitude training is essential for your specific race year.
How do I prevent bonking during a 105km ultra on the mountain?
Bonking—severe energy depletion—is real risk in extended ultras. Prevent it through three strategies: consistent training of fat adaptation via easy long runs and some fasted sessions; meticulous fueling every 45-60 minutes starting early; and practiced pacing discipline that doesn't deplete glycogen reserves before halfway. During the race, never skip aid station nutrition even if not hungry. Carry backup energy (gels, bars) for worst-case scenarios where aid stations provide limited options. Most importantly, consume electrolytes with calories; sodium helps with both hydration and maintaining blood glucose homeostasis during prolonged effort.
What's the best way to train descending for a technical mountain ultra?
Descending skill dramatically impacts both speed and safety on technical terrain. Incorporate dedicated descent training 1-2 times weekly during your peak training block: practice controlled landing technique on steep slopes, develop confidence with shorter strides and bent knees absorbing impact, and build eccentric leg strength through resistance work. Run descents on varied terrain—loose gravel, rocky technical sections, steep grass slopes—to adapt your movement patterns. Practice downhill movement during the latter stages of long runs when fatigued, as that mimics race conditions. Many runners improve fastest by running with faster trail partners who model good technique, then building speed gradually through repeated practice.
How important is crew support for Speedgoat preparation and race day?
Crew support becomes increasingly valuable as race duration extends. For a 105km ultra lasting 10+ hours, experienced crew providing logistics, pacing support, emotional encouragement, and nutrition management substantially improves your performance. If crewing available, plan detailed handoff logistics with specific aid stations and communications protocols. Train with your crew during preparation, establishing systems for gear changes, nutrition management, and pacing feedback. If running without crew, pre-place drop bags at known aid stations and study the course to identify self-sufficient resupply points. Regardless of crew availability, mental preparation for solitude and self-reliance during the race is critical.
When should I do my last long run before Speedgoat race day?
Complete your longest training run 3 weeks before race day, with the simulation including significant elevation gain and back-to-back running if possible. Two weeks out, run a moderate-length mountain run (15-20km with 1000m+ elevation) at goal race pace to reinforce your fitness. During final week, keep running easy and short (5-10km daily runs) to arrive fresh. The 3-day taper period before race should include one short activation run (30 minutes easy with 4-6 x 30sec accelerations) but primarily focus on sleep, nutrition, logistics, and mental preparation. Avoid major changes to diet or trying new products in final days—maintain practiced routines that your gut and mind are accustomed to from training.
