50 MILE ULTRA FAQs

Is a 50 mile ultra a good first ultramarathon?

A 50 mile race is a significant but achievable step up from a marathon or a 50k ultra. Many runners successfully complete a 50 miler as their first ultra. The key is consistent training and choosing the right event. Look for races on GB Ultra Runner calendar with generous cut-off times and relatively flat terrain to make your first experience a positive one.

How long does it take to train for a 50 mile ultra marathon?

This depends on your current fitness, but a runner with a solid marathon base should plan for a dedicated training block of at least 4-6 months. A good training plan will focus on gradually increasing your long-run distance, incorporating back-to-back long runs and practising your nutrition strategy.

What is a typical finishing time for a 50 mile ultramarathon?

Finishing times vary hugely depending on the runners ability and the course terrain and elevation. For a relatively flat 50 mile ultra, finishing times can range from 8 hours for faster runners to 16 hours or more. Always check the race cut-off time, which is the maximum time allowed to complete the course.

What is the difference between a 50k and a 50 mile ultra?

The main difference is the distance. A 50k is approximately 31 miles, whereas a 50 mile ultra is, of course, 50 miles (around 80.5 kilometres). This extra 19 miles presents a much greater challenge in terms of endurance, nutrition and mental resilience. Pacing becomes even more critical in a 50 miler.

What mandatory kit do I need for a 50 mile race?

Mandatory kit lists exist for your safety. While each race has its own specific requirements, common items include: a waterproof jacket, a fully charged mobile phone, a head torch (for early starts or late finishes), a survival blanket, and the capacity to carry at least 1 litre of water. Always check the official race website for the precise kit list before race day.

How should I train for a 50 mile ultramarathon?

Training for 50 mile Ultramarathons UK typically takes 16 to 24 weeks if you already have a solid running base. The focus should be on time on your feet rather than pure speed. Back-to-back long runs on weekends (for example, running 20 miles on Saturday and 15 miles on Sunday) are a staple of 50 mile training to teach your body to run on tired legs.

What should I eat during a 50 miler?

In a 50-mile race, fuelling is just as important as running. You will need to consume between 200 and 300 calories per hour. Relying solely on energy gels can cause stomach issues over 10+ hours, so most runners mix gels with real food offered at checkpoints, such as sandwiches, boiled potatoes, salted nuts and fruit.
