Fitness level

Anyone can take on ultra marathons. Especially you.

Let's bust the myth that ultra marathons are for elite athletes only. Naturally, some people think they are are only for maniacs, experienced in sprinting up snow-topped mountains and crossing vast, barren deserts. But try telling that to the participants! They are mums and dads, nurses and teachers, grandparents and students. They are weekend hikers, post-work yoga masters and two-wheeled commuters. One thing they all share is the belief that more is in them, and with the support of each other, they will make it to the finish!

This challenge will not be easy and it will require a commitment from you to train and prepare for the event, but with enough focus and support, anything is possible.

Are ultra marathons only for elite athletes?

This event has been designed to be a challenge, whatever your fitness level. More serious runners aim for a specific time while for others completing the distance is the goal. Whichever you are, with the right preparation, you can do it!

The aim is for all walkers and runners to cross the finish line with an unimaginable sense of achievement and a lifetime of amazing memories.

I don’t have enough time to train!

Training isn’t easy! Juggling family and social life and work is no walk in the park, however, this event is planned to make your journey as smooth as possible. Above all, you will have an incredible crew and the most incredible community to share the experience and keep you motivated from sign-up to start line.

Training. Where do I start?

Taking on your first ultra uarathon can be daunting to say the least. However, from sign up to start line you will be supported every step of the way, with training plans for walkers and runners, tips, and great offers from partners. You also get access to an incredible Facebook support forum where you can find nearby walkers and runners to help you train, share advice or just share your blister photos!

Absolutely fantastic weekend, friend and I ran this as our first and definitely not our only Ultra. Loved the friendliness of other runners, the pit stops were amazing - well stocked with a great selection of food and drinks. We particularly appreciated the clean portaloos!! Aileen

The beautiful landscape of the South Downs Way was a revelation. The pit stops were well stocked and the crew friendly and helpful across the entire course. I’d recommend this event. Paul

So well organised! Given everything going on it was absolutely brilliant. The aid stations were so well supported and the volunteers were so supportive and attentive. The views were spectacular and well worth the difficult hills. Charly

Amazing race. So well run, the volunteers are fabulous and the pit stops extremely well stocked. Highly recommended. Sarah H

My first ultra, the whole thing from start to finish was phenomenal, what really stodd out was how lovely the support staff were, cheering us on and their words of encouragement were so lovely! Kylie B

Brilliant event! A great intro into ultra, as so well supported and signed. Stunning route. Felt like I had all the information I needed in the lead up and the pit stops and organisation on the day were seamless. Amie F
