How do I train for my first ultra?▾
Most runners build up to their first 50K after completing a marathon. Training typically spans 16-24 weeks with weekly mileage of 40-60 miles, including back-to-back long runs on weekends to simulate race-day fatigue.
Do I need trail experience for an ultramarathon?▾
While many ultras are on trails, some are on roads or mixed terrain. For trail ultras, practice running on uneven surfaces and hills. A 50K on a relatively flat trail is a great first ultra for road runners making the transition.
