Ultra-Trail Mogan by UTMB® Race Day Tips

  1. 1Start conservatively: the first 20km sets the tone for the entire race; many runners go out too fast and pay dearly in the final 40km when elevation compounds fatigue
  2. 2Master your fueling rhythm: practice your exact nutrition strategy during training long runs; the Ultra-Trail Mogan demands consistent calorie intake every 45-60 minutes to prevent the energy crash that ends many ultramarathoners
  3. 3Conquer the climbs strategically: power-hike steep sections to conserve energy while making steady progress; running every climb is often slower than strategic hiking that preserves glycogen
  4. 4Manage mental highs and lows: expect multiple emotional cycles; use pre-planned mantras and focus points to push through the hardest miles, particularly between aid stations
  5. 5Dress for conditions not comfort: bring a lightweight jacket and extra layers despite warm early miles; mountain weather changes rapidly and hypothermia is a real race-day threat
  6. 6Run negative splits: aim to run the second half of the race faster than the first half by banking time early and running conservatively through the middle; this is harder mentally but separates finishers from DNFs
  7. 7Use aid stations as mini-checkpoints: sit briefly, change socks, refuel completely, and reset mentally every aid station rather than rushing through; these 5-10 minute pauses prevent small problems from becoming race-ending issues
  8. 8Practice your headlamp skills: if running into night, test your headlamp on technical terrain during training; poor visibility amplifies fatigue and increases injury risk dramatically on technical descents

Essential Gear for Ultra-Trail Mogan by UTMB®

Trail running shoes with aggressive lugs and rock plate: mandatory for technical mountain terrain; test extensively before race day as blisters on 105km are devastating
Hydration pack (10-15L capacity): carry enough water between aid stations; consider a pack with good ventilation to manage sweat and heat
Lightweight insulating layer: bring a thin down jacket or synthetic layer that packs small; mountain weather shifts unpredictably and hypothermia risk is real
Headlamp with spare batteries: essential for night running potential; test brightness on steep, technical descents during training
Race nutrition: gels, energy bars, electrolyte powder tested during long training runs; ultra-specific fuels like rice cakes or nut butter work better than sweet gels for many runners
Trekking poles: lightweight poles reduce knee strain on descents and assist on steep climbs, often gaining 10+ minutes over 105km
Merino wool or synthetic base layers: moisture-wicking and antimicrobial properties prevent chafing and odor on multi-hour efforts in warm conditions
Emergency first aid kit: blister treatment, athletic tape, pain relief, electrolyte capsules; prepare for worst-case scenarios that arise during extended efforts
Hat or visor: protects from sun and helps with heat regulation; many runners forget this basic element until suffering UV damage mid-race

Frequently Asked Questions

How many weeks should I train for Ultra-Trail Mogan by UTMB® 105km?
A solid training block is 16-20 weeks of dedicated preparation. This allows 6 weeks of base building, 5 weeks of elevation-specific work, 6 weeks of race-specific intensity, and 3 weeks of taper. If you have prior ultramarathon experience, 16 weeks may suffice; if this is your first 100km+ effort, allocate 20 weeks to build the aerobic engine and elevation-specific fitness required. Quality matters more than quantity—consistent week-to-week progression beats random high-volume spikes.
What elevation gain should I be comfortable with before attempting Ultra-Trail Mogan by UTMB®?
You should be able to comfortably complete 30-35km training runs with 1500-2000m elevation gain before race day. During training, you'll build to long runs featuring significant cumulative elevation; these teach your body and mind how to sustain effort when fatigued. For Ultra-Trail Mogan by UTMB®, the specific elevation is listed as unknown on official sources, so check https://mogan.utmb.world for the actual elevation profile. Regardless of the exact figures, your longest training run should simulate at least 70-80% of the race's elevation profile.
How should I fuel during Ultra-Trail Mogan by UTMB® 105km race?
Consume 200-300 calories per hour through a mix of gels, sports drinks, solid foods, and real food from aid stations. The key is practicing your exact fueling plan during 5-6 long training runs before race day. Most ultrarunners find that mixing fuel types—gels early on, then transitioning to more solid foods mid-race—works best. Aim to take calories every 45-60 minutes rather than waiting until you're hungry. Dehydration and electrolyte depletion compound fatigue, so maintain consistent hydration and salt intake. If you've never tested a nutrition plan for 12+ hours, this is your biggest race-day risk.
Should I use trekking poles for Ultra-Trail Mogan by UTMB® 105km?
Yes, trekking poles are highly recommended for a 105km mountain ultramarathon. They reduce impact on knees during descents, assist on steep climbs, and many experienced runners save 15-30 minutes over 100km by using poles efficiently. Practice with them during training—many runners make the mistake of carrying poles without mastering the technique. Start using poles by mile 20-30 when fatigue makes every advantage valuable. Lightweight carbon poles (under 400g per pair) distribute muscle recruitment and preserve the quads and knees for the critical final miles.
How do I train for night running on the Ultra-Trail Mogan by UTMB® course?
Incorporate at least 4-6 night running sessions during your training block, preferably on technical terrain similar to the actual course. Start with 10-15km night runs and progress to 20-25km efforts. Test your headlamp in darkness on varying terrain—steep climbs, technical rock gardens, and smooth single-track all feel different in darkness. Practice changing batteries and understanding how beam angle affects depth perception. Mental confidence matters tremendously; many DNFs occur because runners panic when darkness compounds fatigue. Night running is a learnable skill; the more you practice before race day, the more confident and efficient you'll be if it's needed.
What's the typical race time for Ultra-Trail Mogan by UTMB® 105km?
This depends entirely on your fitness level and the actual course elevation. Check the official website at https://mogan.utmb.world for recent race results and official cutoff times. Elite runners typically complete 100km+ ultras in 12-16 hours depending on terrain; recreational competitors often need 16-24 hours. Your training long runs reveal your realistic pace—if you complete 30km with 1500m elevation in 4 hours, you can extrapolate your expected finish time. Remember that pace naturally slows in the final 30-40km due to cumulative fatigue, so don't assume you'll maintain training pace.
How do I prevent blisters during Ultra-Trail Mogan by UTMB® 105km?
Blister prevention begins with properly fitting trail shoes tested on at least 100km of training. Most runners get blisters because they change shoes too late or use untested socks on race day. Wear socks specifically designed for ultrarunning and bring extra pairs to change at aid stations—swapping to fresh, dry socks prevents blisters better than any blister tape. Consider using Leukotape or similar preventative taping on high-friction areas before the race. Keep feet dry by managing sweat; some runners apply anti-chafing balm to their feet. If a blister develops mid-race, treat it immediately at an aid station—waiting makes it exponentially worse.
Is my aerobic fitness from road marathons enough for Ultra-Trail Mogan by UTMB® 105km?
Road marathon fitness is a foundation but insufficient alone. A 3:30 marathon runner is aerobically strong but lacks the terrain-specific adaptations required for 105km of mountain running. Trail running demands different muscle activation patterns, eccentric strength for descending, and mental resilience for sustained effort. You'll need 12-16 weeks of dedicated trail and elevation training even with strong road base fitness. Don't underestimate the mental component—ultramarathons test your mind harder than your body. A one-month transition from road marathons to ultra training is risky; allocate proper time to build trail-specific fitness.
