Best ultramarathons for beginners in 2023


An ultramarathon of any distance is a fantastic achievement. However, it can understandably be daunting for a beginner to find their first ultra running race/event that seems both exciting and manageable.

There’s a huge variety of ultramarathon events out there, not only in terms of distance but also elevation, terrain, and temperature.

Ultra X have events ranging from 25km to 220km and all of these have their quirks which make them so special. Understandably a 220km event can seem unachievable but rest assured, many of our competitors have never done anything like it before but soon realise we are capable of so much more than we initially think!

International Events (Beginner Level)

International events can be very motivating to work towards because the idea of travelling to an event in awe-inspiring parts of the world, in a location you may never have experienced before really adds to the experience and can inspire you to prepare as well as you can for what’s ahead and make the absolute most of a first ultra marathon.

Ultra X Azores 110/50

A 2-day multistage Ultramarathon taking place on the Island of São Miguel, nicknamed “the Green Island”. This is a wild and remote archipelago, with mountain trails, green pastures, and breathtaking lagoons. This is the ultimate weekend ultra and a great opportunity to see a part of the world you may never travel to otherwise, and, what’s more, the value for money is second to none.

With a difficulty of 4/6 and Technicality of 4/5 and with the 110km having an elevation of 4,069m of elevation it is no easy feat. However, it is around 20ºC which is a comfortable temperature.

For a beginner, the 50km iteration which takes place on Sunday, provides a gentler introduction whilst still experiencing the beauty of the Azores. The 2-stage 110km is a great starting point for those looking to get into the multi-stage scene!

Ultra X - Azores

Ultravasan 45

Taking place in Mora, Sweden this 45km trail races through a beautiful forest and is perfect for those who want to experience Vasaloppet at their own pace. Walk, jog or run, you have eleven hours to finish!

A fast, majority-flat forest road is an excellent option for a beginner looking to conquer the ultramarathon distance without much elevation and on soft ground which isn’t technical.

Blueberry soup and cinnamon buns at checkpoints are a bonus alongside the possibility of prize money with a nice average temperature of 15-22ºC surely make this one appealing!
